Just an FYI, the outermost pouch does not have any pockets inside for storage of things unlike it's counterpart the Heli 18L. It's just a smaller compartment. You pay more for this one basically just to have an extra padding against your back that lets you carry your board horizontally and to insulate your hydration line, and a pocket at the waist strap. The Dakine website gives detailed pictures of the Pro II pack which is another upgrade to this pack. I'm taking this pack next weekend to the slopes, and I'll update if there's anything else to add to the review.
