ThermoBall Eco Vest 2.0 – Men's

When the temperature drops but you still need full range of motion, the ThermoBall Eco Vest 2.0 is our pick for trail runners and hikers who want core warmth without a full jacket. ThermoBall Eco insulation holds its loft even when wet, so a damp Southern morning won't kill your warmth. It packs into its own chest pocket when you don't need it.

• ThermoBall Eco insulation retains warmth even when wet — critical for humid Southeast trail conditions
• Built from recycled materials with a 2.5x2.5 square quilt pattern that locks insulation in place and eliminates cold spots
• Slim fit cuts close to the body for clean layering under a shell or over a base layer without added bulk
• Stows into its own chest pocket — toss it in your pack or clip it to your harness when the trail heats up
• Available in TNF Black, Shady Blue, and Meld Grey in sizes S–3XL, with secure-zip hand pockets for valuables on the move
