These were a Christmas gift for my son. He absolutely loves them and wishes all men’s trousers were this comfortable. Due to current restrictions, he hasn’t been able to wear them to his bouldering club but has managed to scale the house walls and says they allow him a full range of movement. He loves the colour and they are very well made. Well done 3RD Rock Team a 10/10 from him.

Bought for my son (completed this form from his perspective) who is a university student and climbs regularly. I was looking for a pair of good quality trousers that would last a long time and were also ethically sourced. He likes the feel of the material and enjoys the flexibility for climbing.

Absolutely love them! Super comfortable and versatile! I'm a paragliding pilot and wanted something with a lot of stretch but that can take the wear-and-tear of use, particularly in the crotch area (from harness use). Really love the fit and can't wait to get lots of use out of them! Thanks guys!
