Men's Alpine Thermal Bibs

Built for Colorado’s unpredictable shoulder seasons, the Alpine Thermal Bib Short delivers targeted warmth and unmatched versatility for transitional weather. Made with our new recycled Italian fleece-backed fabric, it insulates the thighs and rise without sacrificing breathability or stretch—ideal for pairing with knee or leg warmers on high-effort rides in cool conditions.

The updated fit includes refined uppers for improved support and all-day comfort, while a new zippered pocket offers secure storage for small valuables. Two lightweight mesh leg pockets provide quick access to glove liners or snacks, and stretch-reflective logos and thigh strips deliver over 350 lumens of visibility in low light.

Whether you’re facing brisk fall mornings or the first frost of winter, this bib short is your go-to for adaptable cold-weather riding.

• Italian-milled, recycled nylon fleece fabric is luxuriously soft and strikes the perfect balance of warmth, weight and breathability.
• 4-way stretch, raw-edge uppers provide a seamless feeling fit that accommodates a greater range of rider body types.
• On-bike patterning and updated seam lines for unrivaled comfort.
• Reflective zipper pocket on left leg provides valuables storage as well as additional visibility.
• Elastic Interface® Paris chamois is a time-tested favorite for 6+ hour rides.
• Reflective details throughout for enhanced low-light visibility.

The Alpine Thermal Bib has been engineered with a mid-weight, breathable, stretchy, brushed-back Italian fabric to provide full-upper thermal coverage for cool days. Uppers have been constructed to be minimal, stretchy and also breathable, with lightweight straps and a comfortable mesh-back to hold them in place. The minimalistic design of the uppers and straps reduces bulk under winter layers, promoting quick drying from the inside to minimize sweaty (and inevitably cold) spots that can quickly lead to discomfort in frigid conditions. Additionally, the lighter-weight construction allows for more stretch and better comfort across a wider range of rider body types.

We have also reduced the number of fabric panels and seams, when compared to previous iterations of the thermal bib tights, for increased comfort and a more clean, elegant appearance.
