WEIGHT: 4.2 oz
MSRP: $325
TECH: GORE-TEX with SHAKEDRY™ product technology: 100% nylon

VENTILATION: None

FEATURES: REI claims this is one of the “lightest and most breathable jackets you’ll ever wear.” For just 4.2 ounces, you get an extremely ultralight rain jacket with Gore-Tex technology. The waterproof Gore-Tex laminate defends against wet weather, while the SHAKEDRY permanent technology whisks away the water, without deteriorating the material. The construction of the jacket is breathable enough to mitigate the unpleasant clammy experience of a “wetted out” jacket. The hood has a drawcord to ensure a snug fit, and the arm cuffs and bottom have elastic hems. This jacket is slim fit, so if you’re planning on using a bulkier layer (like a down jacket) underneath, we recommend sizing up. The Norvan SL Hoody does not have pockets or pit zips.

BEST FOR: An ultralight yet extremely breathable shell. If you’re planning on putting up big miles on foot in wet weather, this jacket will keep you from creating your own internal sauna. This jacket is great for trail running or high mileage backpacking trips where speed is the goal. It is also one of the most expensive options.

WHAT WE LIKE: This jacket will keep you dry without overheating during extremely intense exercise. It can be hard to find a proper rain jacket for wet but warm weather, where building up sweat is the last thing you want to do.

CONS: For such a high price tag, this jacket lacks the versatility to keep you warm in dry in the most extreme conditions. Also, there’s no pockets and the thin material is not suitable for bushwacking.

NOTE: This is the lightest jacket using Gore-tex technology. The only one that comes close is the Patagonia Houdini Air, which has DWR treatment and is only usable for light rain and wind. At REI, all sizes are available in the Black/Photon color. Only L/XL are available in the Black/Robotica combo.
