    A light next-to-skin moisture wicking breathable base.


    Micro-fleece channels moisture to absorb quickly, then transfers to outer fabric to evaporate.

  • Technical Warmth

    Grid construction creates dead air space that insulates your body.

  • Comfort Fit

    Minimizing bulk and chaffing with flat seam construction that follows human form.

Experience breathable warmth from the Bask L1 Long John, the evolution of thermal base layer bottoms. Designed with Polartec® Power GridTM, a technical fleece that harnesses excellent moisture wicking properties while providing increased warmth and breathability. Improved fit and comfort is realized with an internal fleece lined waistband and flat seam contoured construction throughout, to minimize bulk. This lightweight long john base layer provides a minimal design that maximizes human performance.

Polartec® Power Grid™ Fabric

The geometric construction generates targeted touch points for the patented design to manage moisture. The next-to-skin surface absorbs sweat vapor and transfers it outside. Then the outer surface disperses moisture for more efficient evaporation. The grid design also creates open air channels that improve breathability, and reduce fabric mass.

Enhanced Comfort

Flat seam construction minimizes bulk & chafing, while a fleece lined waistband makes comfort all day long. Low bulk heat transfer internal label eliminates additional tags.

Ballhalla™ Fly

The Ballhalla™ fly keeps you comfortable all day long with anatomical support and minimal bulk, and the unique design ensures easy access even while wearing gloves.

They work

Bought a set of these for the winter months. Absolutely love the waistband on these. No slide and bunching I under gear or layer 2. The gridded insulation holds heat without added bulk. Definitely recommended for active cold weather use

Cameron Plas
Excellent Base Layer

Hits the sweet spot in being warm without being too warm and manages to breathe decent enough when I get moving, super comfortable and isn't too tight fitting.

Great product, especially for cold skiing

I've tried many different Long John base layers from expensive mountain gear companies and these by far provide the best warmth and fit for your dollar.

Light weight and warm

I've used this twice so far it's worked very well both times , feels good too
