Outdoor Research Foray 3L vs Stratoburst Stretch
Choose the Foray 3L for three-layer construction and TorsoFlo vents that open from hem to bicep. Choose the Stratoburst Stretch for a lighter 2.5-layer shell that packs into a hand pocket. Outdoor Research lists the men’s jackets at 435 g and 240 g.
Based on 194 included owner reviews.
The differences that matter
Both jackets use mechanical stretch, but the constructions differ. The Foray pairs a 40-denier nylon face with AscentShell Dry. The Stratoburst uses 50-denier polyester with Ventia. A thicker yarn number on the lighter jacket does not by itself establish longer service life.
The ventilation layout is the more tangible difference on a warm climb. The Foray’s long side openings extend beyond ordinary pit zips. The Stratoburst has large pit zips and a pocket that doubles as storage, making it a simpler option when the shell often stays in your pack.

Which should you choose?
Choose the Foray if you will use its long vents and chest storage. Choose the Stratoburst if reducing carried weight by the listed 195 g matters more. Check the owner feedback on fit and moisture separately; ventilation openings and fabric breathability answer different questions.
