The DAKINE Heli 2. 0 Pro 26L Backpack adds load lifters to the shoulder straps, so a genuinely loaded pack rides closer to the back instead of pulling at the shoulders over a long day. Back panel and side panel zippered access reach the main compartment without unpacking from the top, and a removable helmet carry tucks away when it's not needed. RECCO Technology makes the wearer searchable to professional rescuers in an avalanche or lost-in-the-outdoors scenario. What Our Gearhead(R) Experts Are Saying:"I've loaded this pack heavy for a full day out and the load lifters kept it snug against my back the whole way, instead of sagging and tugging at my shoulders by the afternoon."
