Let's just get this out the way first: The 7Mesh Oro is the lightest, most packable, fully waterproof cycling jacket on the market - period. Setting out with just that goal, 7mesh used a Gore-Tex fabric called Shakedry. There’s loads of tech behind this, but what you get is a superbly waterproof, breathable and light product. How light? Let's talk 93g all-in for the medium size...
Most waterproof jackets consist of a three-layer hardshell - essentially three fabrics glued together that all bring different characteristics and form a compromise between waterproofing, breathability and comfort; change the make up, thickness or type of fabric and you get different types of jacket. With the Oro, 7mesh, by using Shakedry don’t need to use the outer layer (usually the most waterproof part), or the glue beneath it. Instead, they simply laminate Shakedry fabric to a lightweight inner fabric to add comfort.
The outer surface on the Shakedry fabric repels water, never saturates and never wears off, needing only a quick shake to leave the surface dry. It’s breathable too, allowing moisture to penetrate it from the inside, effectively working like a one way gateway. This practicality, alongside obvious packability means the Oro is a great option across all four seasons.
7mesh are renowned for their keen attention to detail. They are an incredibly rider-centric brand and round after round of prototyping and pattern altering was undertaken before even final samples were shown to anyone outside of the small cutting room in Squamish BC. YKK retrofitted a custom lightweight slider on the zips, and developed a unique zip installation that removed a layer of tape from the process. Hems were laminated instead of sewn to reduce grams even further, leaving the Oro at 93 grams for a medium.
Weight wasn’t everything of course, the Oro still had to function. 360 degree reflectivity and vents that also act as passthroughs to jersey pockets add further practicality and waterproof, elasticated cuffs add additional comfort.
