I’ve never had water soak through it even in torrential downpours, and it still looks exactly as the day I got it. Material feels flimsy but has held up so far without a single tear despite being snagged a few times. The C5 resists water well but does not create the immediate beads that roll off so readily on the R7s. My perception is that it breathes slightly less well than the R7s, and is comparatively warmer. In contrast to the Shakedry pieces, the C5 has a dry, non-waxy hand feel.

Selected for the Outdoor 100 2019/20 – Here’s our full Gore R7 ShakeDry review. BUY NOW: GOREWEAR.COM Based on my experience, Gore Wear is being too conservative with its sizing recommendation, especially for the US market. Mine is simpler: Buy one size up. I think you may misunderstand all the confusing array of Gore marketing jargon, as you stated, “Gore has terrible naming conventions.” Gore calls SHAKEDRY a “technology” not a 2 layer ePTFE material. The ePTFE is the Gore-Tex membrane itself and Gore has imbued magic sauce for persistant beading (essentially PU, but shhh) and calls it SHAKEDRY technology. Infinium and Windstopper are just labeling names, with Infinium being TM and Windstopper being R (e.g. unregistered trademark and Registered trademark respectively). Think of it as Infinium line of clothing and Windstopper being what it does, stops the wind. Gore is simply trying to merge all of its non-guaranteed waterproof under the Infinium hang tag. Gore also markets Infinium with persistent beading (sound familiary? Like Gore-Tex Shakedry?), but doesn’t call it SHAKEDRY even though it’s still the gore-tex membrane on the outside with persistent beading technology (e.g. SHAKEDRY), but again since white hang tag, not calling it SHAKEDRY. The cuffs are elasticated and don’t have any adjustment. The hem does have adjustment though and this is via a toggled drawcord at the hem.Sizes S-XXL (men’s), 8-16 (women’s) / Proflex waterproof fabric / taped seams / stretch hood with stiffened peak / YKK AquaGuard water-resistant front zip / Velcro adjustment on hood and cuffs. Normally I’m a slim fit Medium. Small tops fit me in the chest and shoulders, but the sleeves are too short. Standard size Mediums are oversized in the body. If you don’t read this section, you’ll get the wrong size, guaranteed. The H5 Shakedry has a “Form Fit,” which Gore Wear describes as: A performance item for serious runners who need to get on with their training in all weather. Also ideal for mountain biking, hill walking and commuting in the rain. As things currently stand, for such a level of breathability, protection and low weight, there’s inevitably going to be a trade-off in one area unfortunately. That being said, developments are certainly being made – The North Face’s Futurelight is certainly one to watch here. Tester’s Verdict

Complete protection from the rain while maintaining breath-ability is a lofty goal: GORE-TEX SHAKEDRY™ achieves it.With Shakedry, Gore turned the structure of membrane-based waterproofs inside out. Instead of sandwiching the membrane in the middle of a laminate, the membrane in Shakedry fabrics forms the outermost layer of the garment, supported by a single fabric layer.
