Baselayers are the foundation of our layering system. An L1 keeps you cool during periods of high output, and they’re the starting point for your system’s moisture transport and heat retention.

Our Midweight Baselayers are warmer, slightly heavier alternatives to standard Baselayers, and can be layered over an L1 for extra heat retention without sacrificing breathability.

The workhorse layer when it comes to insulation. A midweight performance L3 provides exceptional heat retention while on the move and can also be used as a wind-resistant outer layer depending on the environment.

The lowest layer in the system designed first and foremost as outerwear. An L4's lightweight packability combines with wind- and water-resistant protection to make it an ideal choice for rapidly changing climates.

The working layer of your system, an L5 is responsible for the final step of kicking your moisture to the outside. Protection from the elements is balanced against breathability and mobility, making this the go-to protective layer when on the move.

L6 Rain layers offer complete wind and water protection in active and static environments. These garments have fully taped waterproof seams. Our L6 layers are also extremely packable and abrasion resistant.

An L7 is a fortress against extreme-cold environments. Durable construction fight off rain and wind, and excellent, fast-drying insulation retains heat even while wet.

Our absolute toughest protection against the cold, an L8 is designed to retain warmth in climates as low as -70°F. Temperature-regulating insulation and windproof but still breathable micro ripstop make this an ideal layer in both active and static circumstances.
