Lightweight Insulation

Meant to stay on.

These are your go-to layers for high-output days in cold conditions — breathable, lightly insulated, and cut to move with you. Think grid fleece, air-permeable synthetics, and weather-shedding soft shells that shine when you’re grinding uphill but still need some warmth. Whether you're skinning, bootpacking, or just staying ready for that next break in the weather, these layers are designed to work hard and wear all day.
