Yes, I use this in my Dakine Pro II (26 L) and everything fits well. The insulated mouthpiece even will fit into the zippered strap pocket. Used it everyday for 2 weeks straight in Wyoming this winter and its worked flawlessly! Not to mention it was the best price on this site and shipped in a couple days right before my trip!
Justin C Dang, that was quick. Thanks for your help bro!
RYAN T Your Welcome! Ironically, I'm packing it right now for my spring break skiing trip to Wyoming again! Picking up a cleaning kit is a good idea too, the one that comes with the yellow hanger is the best.
