The Trew Gear Women’s Trillium Jacket is built for frigid forecasts, with zoned insulation that delivers targeted warmth without sacrificing mobility. Breathable venting keeps you cool when the laps get heated, then zips back up to lock in comfort for the ride back down. With durable weatherproofing and a flattering women’s-specific fit, this jacket is ready for everything from storm-day pow laps to crisp bluebird mornings.
