Favourite pair of jeans!
Initially bought one pair because I'd heard that they were super stretchy and not restrictive when climbing. They fit amazingly well on me (30W, RL), would describe them as a fairly slim/bordering on skinny fit around the calves, roomier around the thighs - which I think is an accurate carrot fit. Despite the tighter fit around the calves, there is ZERO restriction, and very very easy to move and stretch in! Loved them so much, I ordered a second pair just to have a non chalky backup pair I can wear generally when not climbing! 10/10 would recommend - but be warned that the fit is skinnier around the calves!

Excellent flex
I love these jeans so much. The fit is perfect, especially if you like a skinnier pair of jeans. And the length is exactly the right length of leg. The Diamond crotch flex allows for all the range of motion you could ever need when bouldering or route climbing. If you like quality and fit, I strongly recommend this product to you.
