The Revlo Hybrid Jacket skips the hood for a clean collar that layers easily under a shell or a helmet without extra bulk at the neck. PrimaLoft insulation through the body pairs with zoned polyester-spandex fleece panels at the sides and sleeves, holding warmth while still moving with us. The face fabric runs on 100% pre-consumer recycled 20D nylon, cutting down on new material without giving up warmth. What Our Gearhead(R) Experts Are Saying:"I've worn this under a hardshell on a cold, wet day and never felt the collar bunch up or crowd my neck. It layers like it was built to disappear under another jacket."
