Embrace those early and late season mountain bike rides where there's a good chance of precipitation, chilly dawn patrol missions, or after work night rides with the Ambient Jacket from Giro. With a nod towards fashion as well as function and its relaxed fit, this jacket is just as welcome on the bike as it is off and with its addition of a hood that can fit over a helmet, it extends its warmth and it'll be your go-to jacket quite often. The star of the show is its 4-way stretch, 3-layer windproof material that has a cozy thermal fleece back for insulation. Giro claims a 10,000mm waterproof rating which will help to keep you dry on damp trails while its inner sleeve cuffs further thwart water intrusion, keep body heat in, and plays well with winter gloves. On the sides of the jacket, you get zippered hand pockets for storing ride essentials or parking your hands while waiting at the trailhead or during your buddy's mid-ride repair. Rounding out the features is its 3M reflective details, enhancing your visibility to motorists as you head back to your car or home from the food truck lot.
