Royal Robbins Helium Vest
Product DescriptionThe Helium Vest is a tunic length sweater vest with cap sleeves, a full length hidden snap front opening, and drop-in pockets. It is made of Scotia Knit fabric, a lightweight thermal yarn with a soft hand that compresses down for low-bulk packing. The natural cotton works in tandem with the synthetic fibers to wick moisture and dry quickly. Wool-wrapped nylon and acrylic yarns give this a traditional look with great technology behind it.
