  1. Winter Clothing Winter School 2002

  2. Why Is Clothing an Issue? • Humans can’t normally survive in low temperatures • Weather in the mountains is particularly fickle • Temperature • Precipitation • Wind • Your activity level varies throughout the day • Active • Resting • Sleeping

  3. Your Clothing Must… • Keep trapped warm air next to you • Protect you from wind and precipitation • Keep you as dry as possible (wicking) • Be a flexible layering system • Keep you warm even when wet

  4. Cotton Kills • Absorbs water like a sponge • Water is slow to evaporate • Fibers shrink when wet; ability to trap air and thus insulate is lost • Poor wind protection

  5. Cotton Kills (Part II) Steve Howard, LANL

  6. Clothing must be Versatile! • Dress like an onion YOU Wicking Layer Warm Insulating Layer Shell Layer Cold

  7. Wicking Layer Moves moisture away from skin • Silk • Polypropylene (Cool-Max, Capilene) • Polyester • Spandex, Lycra Expensive = Less smelly...

  8. Insulating Layer Think volume- many thin layers • Fleece - light, water resistant, medium bulk • Wool - bulky, scratchy, water resistant, heavy • Down - light, compressible, NOT water-resistant

  9. Shell Layer Wind and/or Water Barrier • Nylon • Coated nylon • Gore-Tex (or other spinoff DWR products)

  10. Accessories Little Stuff That Matters • Mittens & Gloves (layering) • Hats, balaclavas, neck gaiters • Socks (single vs. two layer) • Gaiters • Goggles

  11. Footwear • Mouse boots • Sorels or Kamiks • Leather mountaineering boots • Plastic boots You will encounter ankle deep mud, slush, and water. Sneakers and Gore-Tex hiking boots don’t cut it.

  12. $$$$$ • Clothing is not something MITOC rents, so you’ll have to get it on your own. • Get items that fit and will last. They can be found cheaply, if you look. • Check out the MITOC Links page for info on web sites and local stores.
