Ultralight Wind Shell
Outdoor Research Helium Wind Hoodie

$119, 5 oz. (men’s medium)

Sizes: men’s XS-XXL, women’s XS-XL


If, besides very low weight, versatility counts for everything in an ultralight wind shell, the variety of places, weather, and seasons I’ve worn OR’s wafer-thin Helium Wind Hoodie speaks volumes about its value. From hiking up and sometimes running down crazy-steep trails in fall and the earliest days of spring in Utah’s Wasatch, New Hampshire’s White Mountains, and Idaho’s Boise Foothills, to the breezy heights of Hawaii’s high point, 13,803-foot Mauna Kea, this shell fended off cool wind while taking up no more space in my daypack than my long-sleeve jersey.

A midweight among ultralight wind shells at about five ounces, the highly packable Helium Wind Hoodie also falls in the middle of its field of competitors in terms of striking an appealing balance between weight, breathability, weather resistance, and durability—making it an ideal choice for dayhikers and trail runners who will work up a sweat while possibly encountering a wide range of conditions short of a full-on rainstorm.

The bluesign-approved, wind- and water-resistant, 30-denier ripstop nylon Pertex Diamond Fuse shell fabric blocked wind very effectively. The fabric uses yarns with diamond-shaped filaments woven together in an interlocking pattern, lending it relatively good durability and abrasion and snag-resistance, especially for a fabric this light, while its flat surface helps the fabric shed water. Still, hiking and running are the best uses for this ultralight shell. I haven’t yet worn it rock climbing and I’m concerned that may risk tears.
