I've had the Cobras for about 50 days riding or so since early last season. They are holding out extremely well and are still waterproof and warm. I just blew a small seam of my right glove from touching the ground while carving/ crummy landings, but they are holding strong. I always had mittens and was always complaining about sweaty hands, but the Cobras are perfect. I don't really notice not having a strap to secure them. I either sit on them or throw them in my jacket and haven't had any problems. No damage from holding my board or grabs.
I was just talking to a friend who has the Cobras and really likes them as well. Durability is not top notch like some brands (Hestra), but worth the $100 or so.
