Absolutely shocked that so many people can climb in jeans. I'd rather go out in shorts in winter than jeans, so restricting!
Agreed. I own Simond and 3rd Rock jeans. But I gave up climbing in them because they restrict my mobility too much in any position with wide feet or high feet. They restrict me in almost every leg based yoga pose as well.
This might be down to the shape of my legs? I've got a very narrow waist and quite thin legs, but nothing out of the ordinary for a climber. Whenever I do any vaguely flexi move/pose, the jeans tend to get constricted/bunched around my thighs, with the bunching then causing restriction around the crotch. If I wanted a pair that were loose enough to not constrict around the thighs, they would be enormous around my waist.
My climbing style does rely a lot on flexibility, but I would have to be super inflexible to be able to climb in jeans without them restricting my movement.
In winter, I often wear a pair of 3rd Rock trousers that only restrict my movement very occasionally. Shorts or leggings are the only leg wear I've found that don't restrict me at all.
