Rental Sizing and Shipping Information Below

Climbing Equipment

Click to Buy/ View Item
Ice Axe w/Leash
  General mountaineering tool. Sizing is important: under 5'7" use a 60cm tool; 5'7"- 6'1" use a 65cm tool; over 6'1" use a 70cm tool. (Too short is preferable to too long). No rubberized grips-they are heavy and do not plunge well into the snow. Make sure that you have a leash that is designed for use on a glacier axe or a leash that you make from 9/16 webbing.
Ice Axe

With flat rather than 'cookie cutter' frame rails. Your crampons should be steel, not aluminum for strength and durability. A combination heel bail/toe strap is a more universal system than a heel and toe bail system. We strongly recommend crampons with anti-balling plates

Adjustable 3 section Ski/Trekking Poles w/ Snow Baskets
  Shock absorbers are not recommended.
Trekking Poles

Climbing helmet. Must be adjustable to fit, with or without hat or balaclava on.


  High Altitude Double Boot

A double-boot with high-altitude liners is required for this climb. Plastic shells with a high-altitude liner will suffice. Non-plastic high-altitude double-boots, while more expensive, can be warmer and more comfortable than plastic boots. Note: for climbers seeking summits like Denali, Vinson, or peaks in the Himalaya, an all-in-one triple boot can be used instead of a double-boot for maximum future versatility.

High Altitude Climbing Boot

  Sport Sandals/Water Shoes. For river crossings.
Sports Sandals

Gaiters. Required. Not needed with the Single Boot System

  Wool or Synthetic Socks
  3 pair heavyweight socks to be worn over the liner socks. When layering socks, check fit over feet and inside boots.
Warm Socks

  Liner Socks
  3 pair of smooth thin wool, nylon or Capilene to be worn next to the skin. This reduces the incidence of blisters and hot-spots and makes the outer sock last longer before needing to be changed. They should fit well with your heavyweight socks.
Liner Socks

  Light hiking boots or trekking shoes
  For day hikes and trek to Base Camp. The trail to Base Camp is rocky and rough. Consider a higher-cut boot if you are prone to ankle sprains. Light weight, high comfort, plenty of room in the toe box, and good support should be stressed here.
Trekking Shoes

  Booties. Optional. Synthetic booties.

Technical Clothing

  Synthetic Short Underwear.
  2-3 Pairs of NON-Cotton short style underwear. (boxers, briefs, panties, bras etc.) Amount based on personal preference.

  Lightweight Long Underwear ( M | W )
  2 pair tops & bottoms, Capilene, other synthetic or wool. No Cotton. Lightweight is preferable as it is more versatile (worn single in warmer conditions and double layer for colder). Zip-T-neck tops allow more ventilation options. One set of white for intense sunny days on the glacier and one pair of dark for faster drying gives the most versatility. We recommend purchasing the white or light colored layer with a hood for sun protection.
Lightweight Long Underwear

  Heavyweight Long Underwear Top ( M | W ). For added comfort and warmth.
Heavyweight Long Underwear

Soft Shell Jacket ( M | W )
  Mid-heavyweight. A full-zip version is easier to put on and has better ventilation than a pullover.
Soft Shell Jacket
M | W

Soft Shell Pants ( M | W ). These non-insulated pants can be worn everyday during the climb as they are more versatile than fleece.
Soft Shell Pants
M | W

Hard Shell Jacket w/ hood ( M | W )
  We recommend a waterproof breathable shell material with full front zipper, underarm zips, and no insulation. This outer layer protects against wind and rain.
Hard Shell Jacket
M | W

Hard Shell Pants ( M | W )
  Waterproof, breatheable. Full length side zippers preferred because it allows easy removal of pants, 7/8th zippers allowed but is more difficult to remove pants. No short 1/2 length, or short lower leg zippers allowed as it is difficult to put pants on when crampons are already on.
Hard Shell Pants
M | W

Expedition Down Parka. Must be fully baffled, have an attached, insulated hood, and go below the waist.
Down Parka

Down Pants or Insulated Synthetic Pant ( M | W )
  To fit over insulation layers. Outer shell must be windproof/water resistant.
Down Pants

  Wool/Synthetic Ski Hat. Make sure ears are covered.

  Balaclava. (1) Lightweight model.

  Baseball Cap or other Sun Hat. One with a good visor to shade the nose and eyes. Synthetic (quick dry)
Baseball Cap

  Bandana or Buff. Versatile head and neck wear for coverage from sun and wind. Can protect respiratory system when traveling in dusty conditions.

  Dust Mask. (optional) For those that are sensitive to dust. Can be left at Base Camp.
Dust Mask

Neck Gaiter

Glacier glasses (w/ side covers or wrap around).
  Regular sunglasses are usually not sufficient. 100% UV, IR, high quality optical lenses designed for mountain use, must have side covers and leashes. No more than 10% light transmission. If you wear contact lenses we recommend packing a spare pair of glasses - it is a good idea to have these with "photo-gray" or equivalent light-sensitive material so they can double as emergency sunglasses. If you wear glasses we recommend prescription glacier glasses (gray or amber).
Glacier Glasses

Ski Goggles, 1 pair. Dark 100% UV & IR.
Ski Goggles


  Lightweight Synthetic Liner Gloves
  1 Pair. To wear alone on very sunny days for hand protection or as a layering piece with your Shell mitts.
Liner Gloves

Soft Shell Gloves
  1 Pair. This glove is usually worn alone and during times when the shell mitts would be too warm.
Soft Shell Gloves

Expedition Mitts
  1 pair. Should be large enough to fit lightweight Synthetic Liner Glove.

Heavy Shell Gloves w/ insulated removable liners (Optional)
  1 pair. Though not required, many climbers also prefer to carry a heavy shell glove with a removable insulated liner. Warmer than a light softshell glove but not as warm as the Expedition Mitt, this glove can be a nice addition for use on the upper mountain. Please note that this item does not replace the Expedition Mitten.
Shell Gloves

Personal Equipment

Expedition Backpack
  Internal frame pack expandable to a minimum of 100L (6,000 Keep simple and light, avoid unnecessary zippers.
Expedition Backpack

    Trekking Pack (Optional but recommended).  
      Small pack approx. 2,500cu. in for trek in.
Trekking Backpack

Sleeping Bag
  (Expedition quality rated to at least -20°F). Goose down preferred over synthetic for bulk & weight. If well-cared-for a down bag will last much longer than a synthetic bag. Your bag needs to be long enough that your feet are not pressing out the foot box which will make you colder. It should be roomy enough for comfortable sleeping but snug enough for efficient heat retention.
-40 Degree Sleeping Bag

  Compression Stuff Sacks for reducing volume. For sleeping bags and down clothing.
Compression Stuff Sacks

Self-Inflating pad
  One 3/4 or full length pad. Make sure to include a valve stem and patch repair kit.

Closed Cell Foam Pad

Headlamp (Batteries not Included in Rental)  
      Bring spare bulb & batteries. No Halogen bulbs: they take more power and have a shorter life.

  Cup: 16oz. plastic mug with lid (retains heat well and is spill-resistant in the tent).

  Spoon: Good quality tough plastic (lexan).

  Bowl: 2-cup capacity with lid. We recommend a collapsible or packable bowl to help save space in your backpack.

  SPF 40 or better, 2 small tubes. Note: Sunscreen older than 6 months loses half of its SPF rating, make sure that you have new sunscreen.

  Lipscreen. SPF 30, at least 2 sticks. Make sure your lipscreen is new.

  Water Bottles
  (2 1 litre capacity bottles) Bottles should be wide mouth made of copolyester (BPA free plastic). No water bag or bladder systems, they freeze or are hard to fill and no metal bottles as lips have a tendency to stick.
Water Bottles

    Hydration Reservoir.  
      Optional for use on trek to basecamp. Not a substitute for water bottles above basecamp.
Hydration Reservoir

  Water Bottle parka. (optional)
  Fully insulated with zip opening. Neoprene "cozy" style does not provided enough insulation and is not recommended.
Water Bottle Holder

    Water Purification tablets.  
      1 bottle. Water filters are too heavy and clog quickly with silt. Steri-Pen also acceptable.
Water Purification Tablets

  Pee Bottle (1 Liter).
  Large mouth, clearly marked water bottle. Collapsible 1 liter canteen takes up less volume than a bottle when empty.
Pee Bottle

  Pee Funnel (for women). It is a good idea to practice, practice, practice.

  Hand warmers and Toe Warmers
  Bring 3 sets of each. Toe Warmers are different that hand warmers. They are formulated to work in a lower oxygen environment, like the inside of a boot, they also burn out more quickly.
Hand and Toe Warmers

  To line stuff sacks and pack. Trash Compactor bags are made from a heavier plastic.
Trash Compactor Bags

  Camera gear: We recommend small instant or point and shoot cameras. Disposable cameras work great. For the best pictures bring slow speed film, 50-200. Digital cameras work well but require a greater degree of attention.


  Travel Clothes. In Mendoza: It is hot, so shorts and t-shirts etc. work well. Trek: Very lightweight trekking pants and long sleeve shirts to protect from sun & dust while staying cool.
