The F1 Midweight baselayer pants will keep you warm and comfortable on brutally cold winter days. This lightweight but ultra warm base layer features raised hexatron fleece throughout that provides warmth but allows moisture to dissipate. A Y-elastic waistband  ensures that the F1 baselayer pants fit snug and stay in place.

Layering is crucial to staying warm and comfortable on brutally cold weather days. We recommend using the F1 baselayer pants as your core heating layer that's next to skin then add additional layers like the F2 midlayer fleece pants, and your final rain shell layer like waterproof fishing bibs to complete your cold weather layering kit.
