I heart my Altura Attacks. They do let water up the legs though as they’re open and baggy at the bottom, unless you get the 3/4s or wear them with kneepads which restricts that a lot.
Altura QC seems to be a wee bit erratic sometimes going by other people’s comments on these. I’ve had 3 pairs and they’ve been bulletproof.
One pair I finally wore out after 2 years constant use, the bum’s worn a little thin and isn’t waterproof any more but to put that into perspective- the ride that finally did that to them, also wore completely through the skin in about 20 places over my body too. Very abrasive day out!
I’ve tested them pretty thoroughly in big crashes and they’re probably the most durable shorts I’ve owned.
