Thermal Buddy: What to Wear?
Made for hikers, by a hiker.
Thermal Buddy helps you remember what gear actually kept you comfortable in real conditions. Stop guessing your layering.
How it works
- Record: After each outing, log the temperature, weather, wind, and the exact gear you wore.
- Build: Create your personal database of what worked and what didn’t in real conditions.
- Plan: The night before any trip, surface every past outing ranked by comfort — so you know exactly which base layer and shell combination worked last time conditions looked like this.
