This is a set of four pairs of pants suitable for mountain climbing. The one on the far right is a lightweight and breathable GERRY outdoor pants. The size is L. It's made of a very soft material and is easy to move in. The middle one is Marmot pants. The size is M, but it's a large M. It's made of stretchy material. It's in excellent condition as it has hardly been used. The upper left is HELLY HANSEN shorts. The size is L. It has only been used once and is in excellent condition. It's made of stretchy material and is easy to move in. The lower left is HELLY HANSEN shorts. The size is M. The inside is mesh, and it seems like it could also be used as swim trunks. This is only sold as a set of four, and individual sales are not available. I also have other items suitable for mountain climbing for sale, so please take a look.
