tmthwrote a review of Arc'teryx Stingray Pant - Women's on February 21, 2014
Familiarity: I've used it several times
Fit: Runs small
These pants do run small and that's my experience with the other Arcteryx pants. I bought these to have for a few weeks while my last pair of Arcteryx ski pants (the Volta) was sent in to the warranty center. I skiied in them in the Alps for 6 days in a row, and a few days here in Utah.
First, the sizing. I typically wear a size 8 pant, 150 lbs and 5'7" with a 30" waist and 39" hip... I tried on the medium and it fit, barely, but there was no way I would be able to wear any layers underneath or have full range of movement while skiing/touring. I wish Arcteryx would use pant sizes instead to get a better fit. The non-existent size in between M and L would have been perfect. I got the large. They were a bit more baggy than I'd like but I could wear a layer (or 3) and move around fully. A little on the long side but when you're wearing ski boots its not too noticeable. The pants legs were a good width at the base for my ski boots and boot heaters to go underneath, which was not the case with the Volta. Once I was wearing them for skiing the sizing really didn't bother me whereas in the store I was skeptical.
Pockets are okay. They're not huge. The Sentinel has much better pockets.
The size vents are great although there is no mesh or anything beyond the zipper so if you're wearing shorts, your bare skin will be exposed-- nice for warm touring days but not so much if you fall.
Very high quality which is to be expected for Arcteryx and the price you're paying. The waterproof Gore-tex is awesome. No wet pants, ever. I washed them once with Granger's Performance wash and dried on med/high heat once and the DWR was like new.
I would have kept these pants, except Arcteryx replaced my previous pair and I chose the Sentinel instead.
