Versatility is paramount when mountain biking in cold weather. Have a 1000-foot climb staring at you? It's better to shed a layer before you're overheated half way up. The Gore Bike Wear ALP-X 2.0 Thermo Long Sleeve Jersey uses a unique material that's optimized to push or pull perspiration depending on whether it's worn alone or as a layer with a shell.

A mix of nylon and Elastane give the ALP-X Long-Sleeve Jersey excellent breathability, that's also able to retain heat while pulling moisture to the garments outer layer. From there it's evaporated, or pushed to an outer layer like a windproof shell. That's the beauty of the ALP-X, run it solo when leaves are dropping, and then add another once the frost arrives.

The ALP-X Long-Sleeve jersey features an anatomic, cycling-specific cut with articulated arms and a slightly dropped hem for full coverage in any riding position. It also features anti-slip shoulders to help prevent packs from sliding and bouncing around. If you're into riding sans-pack, you'll appreciate the roomy pockets along the jerseys backside.

Speaking of storage, there's also a zipped Napoleon pocket for valuables. A full-length front zip allows optimization of temperature and keeps sliding into the ALP-X easy. The Gore Bike Wear ALP-X Long-Sleeve jersey comes in Red/Black, Navy Blue/Black, Black, and Castle Grey/Black, with sizes ranging from Small through XX-Large.
