Summit Thermal Jersey - Men's

What Our Gearhead® Experts Are Saying:

"I reach for the Summit Thermal Jersey when I need something warmer than a jersey but more breathable than a shell. The grid fleece is great at keeping heat in and sweat out, and I love how the hood fits under a helmet on cold starts."

The PEARL iZUMi Summit Thermal Jersey is our go-to for variable temps and big-mile days in the dirt. Built with a lightweight, grid-fleece interior, it traps warmth while breathing efficiently—keeping us dry and focused no matter how cold the morning starts. The articulated fit and extended rear hem are made for bike movement, and the slim-fit hood slips neatly under a helmet when we need that extra layer of insulation on brisk climbs or windy descents.

Whether we’re riding it solo in the fall or layering it under a shell for deep winter missions, the Summit Jersey brings trail-focused versatility to every ride. With three zippered pockets and a two-way front zipper for easy venting or rear-access reach, it balances thoughtful storage and performance-driven design to match every season’s pace.
