Arc'teryx - Men's Gamma Rock Pant

Lightweight, breathable, technical alpine pant constructed with two weights of stretchy yet durable textile that provide enhanced abrasion resistance and mobility.

Owl Rock and Rock Guide pants

Arcteryx Rock Guide pants. I am very happy with them, after some OW, and desert climbing. Very stretchy, close technical fit ( more than Gamma LT), and the burly fabric areas are actually VERY durable, and still have a lot of stretch. GREAT belt system that stays put and is super easy to adjust. Not cheap, but worth the $$ if looking for a lightweight technical fit.

When the extended model (tall) will be available?



You need to either use the live chat function or call directly to backcountry. That way they can see if any new shipments are available. There is a possibility they may not even be getting any new stock in until the F13 season starts shipping (aug/sep)

Are you gonna get these Gamma Rock color Heron pants back in stock in a medium to medium/long?

An update: Bought these, and they fit like flood pants, it's ridiculous. I'm guessing these are strictly for guys who climb mountains and need there ankles exposed for whatever reason.. I have no idea why there's a boot hook, these wouldn't even come close to being able to hook onto a boot, unless it's a commando boot. Also bought the Gamma SL Hybrid, and had a similar problem, but the SLhybrid pants were at least two inches longer in the leg, so it's not my long legs, these pants really are just short. Oh and they sag a lot under the ass, on the upper thigh.. I love a lot of arcteryx gear, really dislike all their pants.

There's some great sizing information available on as well as the Arc'teryx website. Arc'teryx does offer Tall sizing in many of their pant styles, which might work better for you.

I think they've updated the pant (bought mine spring 2015) and the length might be a bit longer now. I'm 6'1'' and I got the regular length (medium waist) and they fit perfectly.
