Men's Trailborne 2.5L Waterproof Shell Jacket

The Columbia Men's Trailborne 2.5L Waterproof Shell Jacket is a lightweight, packable hiking shell built for days when the weather turns. Omni-Tech™ waterproof-breathable technology with fully sealed seams keeps you dry in persistent rain, while underarm venting ensures you don't overheat on the climb. A reliable choice for trails and mountain days where conditions change fast.

• Omni-Tech™ waterproof-breathable fabric — fully seam-sealed construction blocks rain and wind while allowing sweat vapour to escape, keeping you dry from both inside and out.
• Fully sealed seams — every seam is taped and sealed to prevent moisture ingress, including at the bonded sleeve cuffs, hood brim, and hand pocket openings.
• Attached adjustable hood — peripheral vision adjustability lets you fine-tune coverage without removing your pack or breaking stride.
• Underarm venting — zip vents under each arm dump heat during high-output activity, reducing the need to stop and layer down.
• 2-way PU-coated zip — the centre front zip opens from top or bottom for flexible ventilation and ease of movement; PU coating seals out moisture when closed.
• Packable design — compresses into its own hand pocket for easy stashing in a daysack when conditions improve; light enough to carry without noticing it.
• Droptail hem — extra rear coverage protects against rain running off your pack and down your back on longer days out.
• Reflective details — low-light visibility on early starts or late finishes.
• 100% recycled polyester shell — more sustainable construction without compromising performance.
