Description

Ridiculously light (only 158 grams!) and 5x more abrasion resistant than its predecessor, the new and improved Helium jacket from Outdoor Research is impressively durable without compromising on bulk or weight. This is a high performance rain jacket and very popular with trail runners, thru-hikers and gram counters. OR has used the innovative Pertex® Diamond Fuse technology for the Helium, which is a 2.5 layer fabric composed of diamond-shaped filaments that lock together to create this ultralight and efficient marvel.
