i am a whore for Arc'teryx shells - i have tried most of the rest at some point or another and for me the bird is it. i feel as lightweight as a ninja but as armored as something out of Halo or some shit. i've had a pair of their pants last me over 300 days in the mountains, probably about the same for the jackets.
I'm looking at getting either the Stingray or the Sabre SV. Have you tried either of these? Are the pants that unbelievable that would warrant shelling out over $300 a pair?
