Fast-moving warmth for alpine starts and exposed terrain in the R1 Thermal Bottoms
What Our Gearhead® Experts Are Saying:
"When it’s cold and I know I won’t stop moving, these are the bottoms I pull on. They breathe better than heavier fleece, block just enough wind, and never feel restrictive when the pace picks up."
Cold starts and long days in the mountains demand layers that don’t slow us down, and the R1 Thermal Bottoms are built for exactly that space. We wear them when the air is sharp and movement is constant, trusting them to hold warmth close without trapping heat when effort ramps up. They feel purpose-built for alpine mornings, frozen approaches, and exposed ridgelines where comfort is earned through motion.
The smooth outer face sheds light wind and flurries, while the microgrid interior manages moisture as we climb higher and push harder. Stretch through the legs keeps movement natural, and the streamlined fit layers easily under shells or softshell pants without bulk. The R1 Thermal Bottoms stay quiet and efficient, letting us focus on the terrain ahead.
