I have never owned such comfortable pants. They move and stretch along no matter what I do.
I now not only wear them to go climbing, but also to festivals, for a day around town... They are amazing and comfy AF!

Strider: The Organic Cargo Trousers of Your Dreams

Back in the early days of 3RD ROCK, one of the first styles we ever created was the Strider, a bold take on the classic cargo trouser. Designed to move with you, endure your wildest adventures, and still look good at the pub afterwards — the Strider quickly became a favourite among climbers, commuters, and outdoor lovers alike.
