What Our Gearhead® Experts Are Saying:"This mountain bike jersey has become my go-to for technical downhill and freeride trails. It’s lightweight and breathable, but thanks to the Power Knit construction, it’s also super durable. I don’t worry about snagging it on branches or taking a spill. The relaxed fit is perfect for layering over pads, and the laser-cut venting keeps me cool even when I’m working hard. The zippered ticket pocket is a nice touch for bike park days, and the built-in lens wipe is a small but super handy feature."When we're charging down technical descents or sessioning jump lines, we need gear that can keep up. That’s why we reach for the Scrub Amp BAT Short-Sleeve Jersey from ION. Built with Power Knit Technology, this jersey combines lightweight comfort with serious durability, resisting snags and abrasions from trail obstacles or unexpected spills. Designed for aggressive riding, the relaxed fit allows us to layer over pads without feeling restricted, while laser-cut venting holes help us stay cool during intense rides. Thoughtful details like a zippered ticket pocket and a built-in lens wipe make it even more trail-ready, whether we’re ripping laps at the bike park or exploring backcountry singletrack.
