    Awesome climbing pants

    • Familiarity: I've used it several times
    • Fit: Runs small
    • Size Bought: Medium Tall
    • Height: 6'2"
    • Weight: 180lbs

    I'll echo what Stan stated in his review about the sizing. A bit trim for an Arc'teryx medium. I found the Medium still fit me like the Gamma LT and Gamma rock but snugger on the waist,
    These pants are perfect for cool weather climbing and being in the mountains. Durable on the knees and seat like the Gamma rock but with a bit thicker fabric elsewhere for cooler weather.
    I love that they added a thigh pocket!
    Can't speak to the long term use yet but they're been awesome for climbing and some cold weather backpacking.
    If you're in the lower end of the size chart, size up. I went with the Tall for extra ankle coverage, I could easily have got the Large and and some room to tighten the belt.

    A Note on Sizing

    • Fit: Runs small
    • Size Bought: large
    • Height: 6'1"
    • Weight: 170lbs

    I struggled getting the fit dialed in with these pants so I thought I'd post here to help others. About me: I'm 6'1", weigh 170-175, 33-34 inch waist and 33-34 inch legs. Pretty typical climber build: tall and lanky. If you're anything like me, forget about the medium, even though it says 33 inch waist. The Arcteryx rep at the Denver store told me that the medium is actually sized from 31-33. For me, I could barely put them on. I got a large, tall and they fit perfectly!
    Regarding the 5 star rating, I haven't even used them yet, but when I tried them on I thought this is the perfect ice/winter climbing pant. The fit, materials, weight all struck me as top notch!

    Super Comfy

    • Familiarity: I've used it once or twice and have initial impressions
    • Fit: Runs small
    • Height: 5'2"
    • Weight: 115lbs

    Love the cinch for the leg opening. Not a hassle to use at all, unlike other pairs I've used in the past. The fit seems to be somewhat small in the waist, but that's about it. Everything else feels great.
