These pants are amazing. I hike, backpack, ride motorcycles, camp, rock climb ect. and these pants can do it all with me. They are very versatile. They have two zippers on each leg to ventilate. They can be tightened at the bottom (3 different snap positions). They have a hook for gaiters. They are stretchy in the crotch and behind the knees. The material is DURABLE. It will outlast all my other gear. I am 5'2", 110 lbs and I ordered a size 36. They fit well but note that I did size up to leave extra room for layering underneath.
I love these pants, they're really comfortable with lots of great utility pockets. The two different types of fabric allow them to fit well, but beware they run small! I'd say order up a size to get a comfortable fit. I also am not crazy about how they taper in at the ankle but for hiking pants they'll be great. I ordered the dark gray/black combo and am very happy.
