What Our Gearhead(R) Experts Are Saying:"I break this jacket out when the forecast calls for steady rain or wet snow because the waterproof shell, taped seams, and synthetic insulation keep me dry and comfortable, and the underarm vents make it easy to dump heat once I start working hard."We zip into the Columbia Trailborne Insulated Jacket when the clouds stack up, and the radar shows nothing but blue and green for the rest of the day. Columbia's Omni-TECH waterproof, breathable membrane and fully seam-sealed construction keep us dry as we hike through steady rain or wait out wet snow at a viewpoint, while Omni-HEAT Infinity reflective lining and synthetic insulation work together to trap warmth without feeling bulky. The attached hood with peripheral adjustment and integrated hidden cord-lock adjustment system lets us fine-tune coverage when crosswinds pick up on exposed ridgelines. As we move, underarm venting lets excess heat escape so we can stay comfortable on long climbs or fast-paced walks through town. Adjustable cuffs and a drawcord hem seal out drafts, and the drop-tail design adds extra coverage when we're sitting on damp benches or scrambling over slick rock. Zippered hand pockets safeguard small essentials and warm our hands, while reflective details add a bit of visibility when the storm lingers into the evening.
