Cold-season hiking, layer by layer
Dress for the climb. Carry the stop.
Put in the forecast for the trailhead, the climb and the clothes you own. The page works out each part of the day - leaving the car, the climb, the stop at the top, the way down - and stacks your layers for each one, free in your browser. Ask for a plan when you want swaps, gaps and a line for when to turn around.
1 The day
2 Your closet
The clothes you could bring, one per line, the way you would say them. Add a weight (280g, 9 oz) if you know it.
3 The stack
base mid puffy shell cotton - drawn skin-out from the bottom. Warmth points and unlisted weights are the page's estimates.

Metered. The plan reads the four phases, your closet and the page's flags, and returns what to wear in each phase, what to swap out, what is missing, a verdict (ready, adjust or rethink) and the sign that should turn you around. It speaks only to clothing and the forecast - not avalanche, ice or trail conditions.
