Born from brisk Colorado mornings and the long, dry climbs of the Front Range, the Alpine Thermal LS Jersey is built for high-output rides in cool to cold conditions. Whether you’re pushing tempo through golden fall canyons or logging base miles in early spring, this jersey balances warmth, breathability, and stretch to keep you performing in temperatures from the low 30s to mid-60s °F—depending on layering.
Crafted from a premium Italian recycled nylon fleece, it offers impressive warmth-to-weight, excellent mobility, and next-to-skin comfort. The refined fit is designed to move with your body during hard efforts, while strategic reflective hits on the forearms and rear pocket panel light up with over 350 lumens of visibility when the sun starts to dip.
We’ve dialed in the pocket configuration for cold-weather practicality: three rear pockets with a slightly wider center “dump” pocket make it easier to access gear with gloved hands, while a zippered valuables pocket secures essentials like keys, cash, or a card.
When the road stays dry but the temps drop, this is the jersey you’ll reach for—season after season, ride after ride.
