I bought these for my Dad and he’s absolutely thrilled with them. He says they’re extremely comfortable and look smart too. He’s quite tall and they fit nicely as well.

I ordered a pair of the Mercury jeans for my partner and he really loves them. The quality and the fit are amazing and the color lasts if you wash the pants with cold water. Those jeans can also be worn as regular jeans to go out and not just climbing.

Love 3rd rock, high quality and generally a good fit. The men’s pants are a little tight on muscular thighs! The women’s pants are amazing and I have several pairs in different colours!
