Crux Flak

Designed as a functional, uncompromising climbing jacket, the Flak is made of 3-layer eVent fabric, so it has top-end levels of waterproofness and breathability. The fabric felt nice and robust too, and ideal for fending off a winter storm. The design is frills-free with just a pair of Napoleon chest pockets that can swallow guidebooks and gloves. The hood is designed to fit over a helmet and benefits from a wired peak plus face and volume adjusters. Movement in the sleeves was excellent and ideal for climbing or mountaineering. The jacket is shorter than some, but you do get a scooped tail to add some protection at the back. So a lot of good features for the more mountaineering-orientated user. But hood movement was not as good as some other jackets here. The main zip does not get a stormflap, so it may not be as waterproof as a zip with a double stormflap. You don’t get pit zips for venting either. It is hard to warm your hands in those Napoleon pockets too. So this might not be ideal for everyone.
