LAYER UP WITH THE LUPINE

There’s nothing worse than calling it early because you’re cold. Underlayers are key to your riding experience. The Lupine Lightweight bottom moisture-wicking fabric ensures that it dries rapidly and the elastic waistband ensures a perfect fit that’s not too snug and not too loose. Layering is key, so unlock your potential on-hill with the Lupine LW bottoms.
