Wow. This is the most amazing daypack out there. It has so many features, is built really solid, and flat out looks sick. I use it for school, travel, and skiing. The black chop shop graphic is really loud and sticks out. This pack has a small profile, so you can wear it on the lift, but is deceivingly roomy inside. The reason I chose the Pro II over the Heli Pro is the better, more stable ski carry system and more overall compression for smaller loads. It looks like it can hold skis up to around a 120-130mm waist, so if you're rockin the K2 Pontoons or other fatties, this should work better than the Heli Pro. The snowboard carry system works great for boarders, and carries a skateboard as well. It takes awhile to get acquainted with this packs features since theres so many. The main compartment is accessed through the backpanel, which is nice, and a smaller zipper on the top. For an inbounds day, you can throw your lunch inside and cinch down the straps knowing your load will not move around, or load it up with avalanche gear, skins, a puffy, helmet, food, water, camera, spare gloves and goggles, and an ice axe. This pack will carry anything you might need for a full day of big mountain riding. I highly recomend this product, it will last a very long time.
