About the ThermoBall Trekker Vest
The vest version of the ThermoBall Trekker Jacket: the same 11.5 g/ft2 recycled-polyester ThermoBall insulation, contoured into streamlined baffles that fit the body and hold core warmth in cold, wet conditions.
Packable, insulated, and sleeveless
Two colorways (Mid Grey, TNF Black) at $192.51, sized S–3XL. Like the jacket, it stows into its own hand pocket for travel — genuine packable insulation for a team that wants ThermoBall's warmth without the sleeves.
