Ice Axe

$44.00

A general mountaineering ice axe. Size according to height; under 5'2'' use a 50 cm axe, 5'3'' to 5'5'' use a 55 cm axe, 5'6'' to 5'9'' use a 60 cm axe, 5'10'' to 6'0'' use a 65 cm axe, above 6'0'' use a 70 cm axe. If you already have and prefer to use a waist leash, you are welcome to bring it to your gear check.

Accessory Cord or Pre-Cut Prussiks

40 feet of 6mm accessory cord to be used for prussiking and other climbing rigging. Bring pre-tied prussiks if you already have them, or bring one continuous length to be cut.

Crampons

$62.00

General mountaineering crampons. We recommend modern steel 12-point crampons with anti-balling plates. We do not recommend 10-point, aluminum, or single-piece rigid crampons. The traction offered by a 12-point crampon is superior to that of a 10-point; steel crampons stand up to the rigors of potential time spent walking on rock in crampons; one-piece crampons often break or do not fit modern boots well.

Carabiner System

You will want exactly the right climbing hardware for your climb. Follow this list carefully: two (2) large oval wiregate carabiners; two (2) smaller wiregate carabiners; one (1) large pear-shaped locking screwgate carabiner; one (1) large locking carabiner (can be auto-locking). If you have any questions about your carabiners, please contact the Gear Department.

Alpine Climbing Harness

$50.00

Your harness must fit over all of your clothing, feature gear loops, adjustable leg loops and waist belt, and must be able to fully separate at the legs and waist. We strongly recommend newer models with a belay loop and which do not require "doubling back" your waist belt- older models can be very cumbersome. Old Black Diamond Alpine Bod type harnesses are not recommended.

Belay Device

Modern tube-style belay device. Avoid super-specialized belay devices which cannot accept a wide variety of rope diameters.

Trekking Poles

$55.00

Collapsible skiing/trekking poles with snow baskets. Three-section varieties are preferred.

Ascender

$40.00

One right or left-handed ascender (pick your dominant hand to choose which style ascender). This item must be in good condition.

Footwear

High-Altitude All-in-One Boot

Used instead of the high-altitude double-boot, this all-in-one integrated boot system is warm enough for use without overboots, and eliminates the need for gaiters.

Camp Boots

Optional. Insulated, non-technical winter boots for time spent around Base Camp.

Insulated Camp Booties

Down or synthetic insulated camp booties for use inside boot shells or when sleeping in your tent.

Light Hiking Boots or Trekking Shoes

For any approaches across dry trail. Light weight, high comfort, plenty of room in the toe box, and good support should be stressed here.

Wool or Synthetic Socks

Four (4) pairs of heavyweight socks. If using liner socks, these must be sized to fit with your liner socks. Check the fit inside your boots, and be sure to bring new socks.

Liner Socks

Four (4) pairs of smooth, thin non-cotton socks to be used as liner socks to be worn underneath your wool or synthetic socks.

Technical Clothing

Baselayers - Top & Bottom

Two to three (2-3) each of lightweight baselayer pants, long-sleeved shirts, and short-sleeved shirts. Non-cotton fabrics only- consider merino wool blends or synthetic fibers such as polyester.

Heavy Baselayer Bottoms

Heavy, expedition-weight baselayer bottoms designed to be used while climbing in very cold conditions. Fabrics such as Polartec Power Stretch, Capilene 4, and Polartec Power Dry will work well.

Midlayer Top

A midweight, form-fitting, lightweight fleece layer for use over baselayers. Hoods are optional but recommended.

Trekking Pants

1-2 pair of lightweight nylon trekking pants. We recommend models that are simple, made with synthetic fabrics, and offer pockets for convenience. Zip-off models are not required, but are preferred by some.

Softshell Pants

$60.00

Stretchy, comfortable, non-insulated softshell pants that should fit comfortably with or without your baselayer bottoms. Please note that "zip-off"-style trekking pants are too light to be considered softshell pants.

Softshell Jacket

$60.00

This breathable but wind-and-weather resistant jacket is a key part of a mountaineering layering system. We recommend a hooded model. This layer must fit well over your midlayer top and baselayer top.

Hardshell Pants

$100.00

Non-insulated, fully waterproof shell pants that must fit comfortably over your baselayer bottoms and softshell pants. Full-length separating size zippers are strongly preferred; shorter side zippers are allowed if you can put on and take off your pants without removing your footwear.

Hardshell Jacket

$100.00

A non-insulated, fully waterproof shell jacket with a hood. We recommend durable three-layer fabric. Goretex Pro Shell or a similar eVent fabric will offer the most durability and long-term weather protection. This layer must fit comfortably over your baselayer, midlayer, softshell, and potentially a lightweight insulated layer. Helmet-compatible hoods are required.

Insulated Synthetic Hooded Jacket

$63.00

A synthetic insulated, hooded jacket sized to fit comfortably over your baselayer and midlayer.

Expedition Down Parka

$250.00

An 8000-meter rated, expedition ready parka. This parka must be in excellent condition, fully baffled, and should be recently cleaned with Nikwax Down Wash to ensure maximum loft. We recommend calling to discuss your parka choice, as this item is key to success on any expedition.

Expedition Down Pants

In complement to the Expedition Down Parka, these heavily insulated down pants must be sized to fit over all other layers, with a weatherproof outer shell fabric.

Down Suit

This item is optional but recommended. If electing to use a down suit, separate down pants and a down parka are not required, as they are replaced by the suit.

Insulated Synthetic Pants

$60.00

A synthetic insulated pant with full-length separating side zips. Ski pants are typically not appropriate for this layer.

Handwear

Lightweight Liner Gloves

Very lightweight wool or synthetic liner gloves that offer a snug, comfortable fit. Lighter colors absorb less sunlight while still offering UV protection. Black or dark-color gloves are also acceptable.

Softshell Gloves

$40.00

Midweight, lightly insulated gloves for use when mittens are too warm and liner gloves are not warm enough. Leather-palm construction is always ideal for the sake of durability.

Insulated Shell Gloves

One pair of warm shell gloves with insulated removable liners. Excellent for use when conditions are too cold for softshell gloves, but too warm for expedition mittens. We recommend models with a durable leather palm.

Expedition Mittens

$63.00

Expedition-rated mittens with an insulated removable liner. Please be sure this mitten is the warmest model available by any manufacturer.

Headwear

Climbing Helmet

$40.00

A lightweight climbing-specific helmet. This must fit comfortably over your bare head, hat, and/or balaclava, and your headlamp must be able to strap securely to the outside of the helmet.

Buff

A must-have for all outdoor activities, the UV Buff is a versatile replacement for the bandana and serves a multitude of purposes.

Sun Hat

Any style of lightweight hat for shading the head will work well. Baseball caps and sombrero-style sun hats are the most common.

Balaclava System

Two full balaclavas, one heavyweight and one lightweight, that will comfortably layer together. These items are not replaced by a Buff.

Facemask

Neoprene models are recommended; be sure your facemask is sized well to your face. Balaclavas with built-in facemasks will also work well.

Glacier Glasses

$45.00

High-quality glacier glasses offering full coverage around both eyes and across the nose. Removable side-shields are not required provided eye coverage is sufficient.

Ski Goggles

$50.00

High-quality goggles for sun and wind protection at altitude. The lens should offer visible light transmission (VLT) of no more than 30%. Those with light-sensitive eyes may wish to use a darker lens. Photochromic models are ideal for use in changing conditions. See here for more.

Nose Guard

Nose guards are optional, but can be useful for those with extra-sensitive noses in lieu of constant sunscreen application.

Headlamp

$33.00

A modern outdoor LED headlamp offering 90-200 lumens of output. Freshly installed batteries plus spare batteries. Weather-resistant models are strongly preferred.

Personal Equipment

45-Liter Climbing Pack

Capacity is approximate. Keep it simple and light. We will use this pack on the trek in to base camp.

Expedition Backpack

$85.00

An expandable expedition climbing backpack with approximately 75-liters of carrying capacity. Keep it simple and lightweight. Climbing-specific designs are recommended.

-40 Down Sleeping Bag

$250.00

This sleeping bag should be appropriately rated to -40 degrees. Down bags are a must- synthetic bags are overly bulky and heavy when rated below 0-degrees.

-20F Down Sleeping Bag

$200.00

This sleeping bag should be rated to -20 degrees Fahrenheit and must be down-filled rather than synthetic filled for the sake of weight and bulk. Be sure to include a correctly sized compression stuff sack. Those who sleep cold should strongly consider a -40 degree sleeping bag.

Inflatable Sleeping Pad

$47.00

A full-length, modern inflatable sleeping pad is recommended. Older-style three-quarter length pads have been superseded by ultralight full-length pads. We recommend bringing a valve repair/body patch kit.

Foam Pad

$30.00

This pad should be either 3/4 or body length. Cut pieces of closed cell foam or industrially-crafted pads are both acceptable.

Water Bottles

Two to three one-litre capacity bottles. Bottles should be wide mouth made of co-polyester (BPA free plastic). No water bag or bladder systems (they freeze or are hard to fill) and no metal bottles (they have a tendency to freeze).

Mug

One insulated outdoor-style mug with a removable lid. Your mug should retain heat well and be spill resistant. Models with 12-20 oz capacity generally work best.

Knife

Medium-sized. Keep it simple and light.

Pee Bottle (1-1.5 Liter)

One wide-mouth, clearly marked collapsible container or wide-mouthed bottle for use overnight.

Spoon

One durable hard plastic or anodized metal spoon. Longer spoon stems can be helpful for eating while wearing gloves.

Water Bottle Parkas

Bring two fully insulated water bottles parkas with zippered openings. Neoprene 'cozy' style constructions do not provide enough insulation and are not recommended.

Pee Funnel (for Women)

Optional. Practice is critical for the use of this item.

Bowl

One two-cup capacity packable bowl. Models with a lid (like a Tupperware) work well, as do lidless bowls and flatter "deep plate" models. Collapsible models can suffice, but must be handled very carefully to avoid unintended collapsing.

Thermos

A fully vacuum-insulated thermos is recommended for hydration, comfort, and safety on cold days on the mountain. One-liter sizes are strongly preferred, and avoid narrow-mouthed thermoses which can be challenging to fill.

Trash Compactor Bags

Three bags for use as waterproof pack/stuff sack liners. Compactor bags are made from a heavy plastic and stand up well to prolonged mountain use.

Camera

Optional. Small point-and-shoot cameras (including compact SLR's) are ideal & work well at altitude. Alternatively, many opt to use a smartphone camera. Due to weight & care in the mountain environment, large dSLR cameras are discouraged.

Large Duffel Bags

Two (2) large duffel bags should be used for transporting all gear to basecamp. Bags with rollers or wheels are not accepted. Soft-sided, water-resistant duffels are required.

Water Purification Tools

We double-treat all drinking water. Bring several bottles of chemical-based water treatment, such as AquaMira, as well as one Steri-Pen device per person. The Adventurer-Opti Steri-Pen is the recommended version due to long battery life and reliability.

Toiletry Bag

Include toilet paper (stored in a plastic bag), hand sanitizer, toothbrush, toothpaste, floss, and wet wipes. Choose a quantity appropriate for the length of your trip, and call the Gear Department with any questions about these items.

Sunscreen

One to two ounces of SPF 30+ sunscreen. Varieties with zinc-oxide are more protective! One ounce is typically sufficient per week, but several small tubes can offer insurance against lost or exploded tubes. Sunscreen loses SPF rating over time; we strongly recommend brand-new sunscreen.

Lipscreen

Several tubes of SPF 30+ lipscreen. As with sunscreen, be sure your lipscreen is new.

Running Shoes

Lightweight, comfortable running or walking shoes are recommended for off-mountain use and pre-and-post trip travel. In some situations, these may also serve as approach shoes.

Small Personal First-Aid Kit

Basic medical supplies in a compact package. We recommend basic painkillers, Moleskin, first-aid tape, Band-Aids, and anti-septic wipes or gel.

Medications & Prescriptions

Bring any personal prescriptions, plus Pepto Bismol, Cipro (500mg tablets), Metronidazole, Z-Paks (250mg tablets), Diamox (125mg tablets, approx. 2 per day at altitude), and a variety of standard painkillers like Excedrin Extra Strength, Ibuprofen, etc.

Hand and Toe Warmers

Bring three sets of each. Please note that toe warmers are different than hand warmers. They are formulated to work in a lower oxygen environment, like the inside of a boot, they also burn out more quickly.

Base Camp Comforts

It is good to bring additional other items which you have previously found useful- playing cards, music players, board games, reading tablets, etc.

Food

Please review the food and water information available in your Climber Information Packet. A close reading of this information is important towards a smooth trip. We recommend taking plenty of time consider this information. Please contact the Gear Department with any food-related questions.

I thoroughly enjoyed the expedition. Everyone was very supportive, considerate, and caring to the climbers on the expedition. Even though this is the first AA expedition where I did not summit, I will say it was one of my favorite in large part due to Ben, Lakpa, and Tshering.
