I ordered the impossibly rare Axiom Jeans, but then was quickly notified that there were in fact out of stock in my size. Not really feeling like waiting a month for more stock to arrive I decided to just go ahead and give the Zion's a try.
Well, let me tell you I couldn't be happier with my decision. These pants fit PERFECTLY in Medium for me (I'm 6'0" 174ish lbs, 31-32" waist, 32-ish inseam), I just had to cinch up the belt slightly and it's perfect. The inseam is perfect for casual wear and with the provided snaps its super easy to securely roll up the pants for some serious heel hooking. At first I was worried that the pants would be inflexible and restrictive, but I swear they are shaped perfectly for climbing/yoga/whatever...I can honestly say that I have never owned a more comfortable pair of pants, including sweatpants - the fit, cut and material is just that good.
As far as climbing is concerned, I almost always climb in jeans...its just my style and while they were super flexible, there were still certain moves that made me a little nervous that I'd hear a loud rip and then give the whole gym a show. With the Stretch Zion pants I can do any move with total confidence and without any feelings of restriction whatsoever.
As far as the durability is concerned, all i can say is that upon inspecting them they appear to be very durable. I am a little iffy on how the material would handle technical mantels, or the occasional knee-bar. But when it comes time to test the durability, I'm sure I will be surprised and incredibly impressed with these pants yet again.
Oh, and I got the Cypress pants...they ARE green, but it's a dark olive color with sort of a light grey overtone. I was afraid they'd be more like forest green, but that's not at all the case.
Bottom line get these pants...actually get two pairs because you'll probably never want to take them off.
