In reply to Petarghh:
Just a warning for you. I had a pair of the original Marmot Hueco trousers made of heavy duty cotton and purchased another pair expecting the same fit and fabric, the design has however been changed to a lighter fabric and a much more relaxed fit (massive baggy clown trousers). I personally think the new design is terrible and so sent them back for a refund and ended up having to search out some other trousers for bouldering and cragging.
