Looking for a superlight waterproof breathable shell? Don't let the anonymous name prevent you from looking at REI's Summit Lake jacket. It's got the goods you normally have to pay more for, all wrapped up in a svelte 11oz package.
The Summit Lake starts with REI's proven Elements ripstop nylon laminate shell and adds sealed seams to ensure waterproof performance. We really like the full-length rubberish zipper flap: it won't get caught in the zipper and it makes using the full-size zipper very smooth. The pit zips are also smooth, unusual for a lightweight shell.
All the other good stuff is here too: velcro rip-and-stick cuffs, chamois zipper garage, hem drawcord and roll-away hood. The hood is a nice design, roomy enough for a helmet and with a stiff brim that provides good peripheral vision. Be warned: there's just a single external chest pocket with a smaller nested velcro MP3 pocket and cord port inside. No hand pockets, which may or may not be a big deal to you. Overall the fit and finish are superb. While some superlight shells make you look like one of those hairless cats with all the wrinkles, the Summit Lake hangs nicely enough that you won't think twice about wearing it about town.
