Wearables - be W.I.S.E
You’ve heard that there is no such thing as bad weather, just inappropriate clothing. Here’s some “appropriate” clothing for adverse weather and water.
The Appalachian Mountain Club recommends an easy mnemonic for preparing for adverse weather and water - Be W.I.S.E. - here’s a link to an article by Matt Held with details. Briefly:
W is for Wicking - the innermost layer that moves moisture away from your skin
I is for Insulation - the middle layer(s) that provide warmth - can be multiple layers to allow for adjusting to conditions and levels of exertion. Should be material that stays warm when wet.
S is for Shelter - the outermost layer that protects the insulation from the weather - rain, snow, etc. Rain jackets, dry suits, windproof shell. Similar to Insulation, how much and how little depends on conditions and activity.
E is for Extra - carry spare stuff in case. We think it also includes hands, feet and head - which need equal protection and care. There is a separate page for shoes and gloves.
