P. McBride wrote a review of Arc'teryx Stingray Pant - Men's on February 10, 2012
Yes, 5 stars, this are very, very good pants. I'm a fan of the attention to detail of Arc'teryx and these are no exception. A technically outstanding pant with side vents being particularly useful to open up at base camp without letting too much cold air in.
The temperature regulation is excellent, particularly if you like to wear base and/or mid layers, which I do.
The snow and condensation just falls off these pants as expected, and more importantly, doesn't get into them with internal calf cuffs inside the pant sitting above the re-enforced sidewalls doing a great job, you just wouldn't know they're there. The Recco reflector adds peace of mind and is not conspicuous at all.
They look great, too. Medium at 168lb and 5'9" made for a perfect fit.
