The Stratoburst Stretch is a great, lightweight 2.5 layer shell suitable for a variety of activities. I would reccomend this jacket to someone looking for a light shell for day hikes, or multi-day hikes in fine weather, or as an urban/travel jacket. A number of customers have also picked this up for mountain biking as the longer fit of the jacket and 4-way stretch through the shoulders makes it suitable for the cycling position. While a tempting option due it's light weight, it's important to understand the limitation of 2.5L jackets and their ability to withstand a prolonged period of heavy rain and would not reccomend this for use in more inclement weather.

Fit tip:

Slim and longer
