micwebwrote a review of Marmot Stride Vest - Men's on October 9, 2015
Familiarity: I've put it through the wringer
Fit: True to size
Marmot has two "classics" that have been around well-over a decade: the Windshirt, and the Windvest. Both are thin - maybe ultrathin - tight-weave shells with underwear-weight "base layer" material as a lining. I've been collecting/hoarding/using these things for years - they don't wear out, unless you are REALLY rough on them, and they are so darn good that when they go on sale once a year or so, I usually grab another one.
There are some minor differences over the years: the original vest was, indeed, called the Windvest or Wind Vest, and now it's the Strider; the original had no handwarmer pockets, then open, unzippered pockets, and now the Strider has twin, full, open-from-the bottom handwarmer zipper pockets; the original had a shallow zippered vest pocket that was horizontal, then a side-entry vertical vest pocket along the main-zipper seam (still zippered) that was bigger, now an angular vest pocket, still zippered. And oh yeah, for a few seasons, Marmot left the mid-back unlined - just the front, sides, and shoulder yoke were lined.
Most significantly, the weight fattened up to 8-10 ounces for Medium at one point, but now it's back down to 6 ounces plus change - much more packable.
THIS EXCELS for fast and light hiking and travel. Basically, IT IS AS WARM AS 200 POLARTEC, but lighter, packs down smaller, and is wind and rain (mostly) proof.
The toughest choice you need to make is: are you a vest person? or a jacket person? For travel on a cold plane, the vest is probably enough. For cold mornings or evenings in camp, go with the jacket. I've hikes in autumn rains with nothing more than the jacket and a hat to keep the rain off my face - body heat from hiking keeps the jacket lining dry, the nylon surface wets out eventually but keeps most of the rain out and hence the lining dry, and me dry too.
NEITHER or enough if there's snow on the ground. You need down for that. BUT if you aren't expecting rain, one size up on a jacket and it will fit over a thin down jacket underneath.
Ray Jardine and other ultra light hikers swear by "wind shirts" as one of the fundamentals in a layering system. This adds a very thin insulating layer to an unlined windshirt, and has the greatest longevity in the marketplace of any I know.
