Never have had any stone glacier gear but that is likely to change. Given the opportunity to run this hoody during shed season and I like itYou never have enough hoodies.....right! Was thinking I would need a medium but glad I got a large at 5’7” 160 fits perfect....after a 6 hr play day in the snow in high 20s high exertion day wearing only the hoody first takes are wicks extremely well, using the zipper to dump quick heat and then as I slowed and cooled back on the zipper...gonna keep wearing many days before washing...excuse the hair did not have time to comb it
