Winter Clothing
Winter School 2001
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
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
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

Wicking Layer
Moves moisture away from skin
• Silk
• Polypropylene (Cool-Max,
Capilene)
• Polyester
• Spandex, Lycra
Expensive = Less smelly...
Insulating Layer
Think volume- many thin layers
• Fleece - light, water resistant, medium bulk
• Wool - bulky, scratchy, water resistant,
heavy
• Down - light, compressible, NOT waterresistant
Shell Layer
Wind and/or Water Barrier
• Nylon
• Coated nylon
• Gore-Tex (or other spinoff DWR
products)
Accessories
Little Stuff That Matters

Mittens & Gloves (layering)

Socks (single vs. two layer)
Gaiters

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.
$$$$$
• 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.
