Lightweight fleece jacket with revolutionary air flow system.

Professional skiers, climbers and sailors challenged us to offer them the most versatile jacket imaginable. Because they encounter every type of weather imaginable. We created a jacket with the H²Flow unique air pocket body temperature regulation system that retains body heat when you need it and let you ventilate it out when you want to. The ultimate middle layer or stand alone jacket for outdoor athletes who never want to come inside.

H2 FLOW JACKET is rated 4.5833 out of 5 by 12.
Rated 5 out of 5 by from Best jacket I've owned I use it for day hikes in temperatures ranging from cool to a little below zero. It keeps you warm during casual walking and once your body temperature rises with activities the two front zip vents actually do work to cool you down. It is light as a feather and can also be used as a base layer under a bigger outer jacket. Great in the wind, haven't worn it in steady rain. I love its versatility and performance.

Rated 4 out of 5 by from Lightweight, but well-insulated As part of Abilyn Racing (, a sailing team based in New York, my co-skipper and I first began wearing the H2 Flow jacket in mid-April, when the weather in the northeast U.S. was still fairly cold. The jacket has served us well as both a mid-layer and outer-layer sailing jacket. The material of the jacket is not only very lightweight, but very well-insulated given the unique design. We tested the jacket in a wide-range of conditions including temperatures down to about 35 degrees F. The H2 Flow coupled with HH Warm baselayer gear is our go-to combination of initial layers for cold-weather sailing, and can be utilized equally to other outdoor sports. As temperatures warm up and base layers are shed, the H2 Flow allows you to expel heat through two vents located on the torso. These do a good job, but we'd much prefer those vents to be located under the arm pits to maximize heat dissipation. Overall, we're quite satisfied with both the look and feel of the H2 Flow jacket. Keep an eye out on the outer material. Because the material is thin, it tends to get snagged in luggage zippers. See you out on the water (or wherever else your adventures take you).

Rated 5 out of 5 by from Great all around piece This jacket is great for being used as a base layer when you're out in the mountains or as an around town jacket. It is incredibly light for the amount of warmth it provides.

Rated 5 out of 5 by from H2 Flow Jacket Volvo Ocean Race This Jacket is fantastically effective for its Bulk. Traditionally mid payer jackets can be very bulky. And are difficult to use in terms of regulating heat. This jacket is very thin, for the warmth it retains, but also seems to allow easy heat regulation, and dries very quickly. One of the best items of clothing to come out if the Volvo Ocean Race development done by HH.
