Replaced my beat-up SOUTHWEST with Waypoint 35 for this season. Among other thing, I use this pack to hike AZT this year. The pack was great overall and internal frame helped me carrying heavy water during the dry sections of the trail. One note for people planning to use this pack to hike AZT is that, like any Dyneema-base pack, the material does not handle abrasive desert terrain really well and easy to poke hole on the pack. So be gentle when putting the pack down. And ensure to carry repair kit to fill scratch and holes as they are inevitable.
Only negative point I experienced for this pack was the chest straps or rather how easy they detach from the pack. Unlike SOUTHWEST, the chest strap is just hooked to shoulder straps and easy to fall for some reason. I lost mine about halfway through AZT and I can tell you it was not fun to carry pack without chest strap to stabilize. So hope Hyperlite improve the design of chest strap so that it does not fall easily when not under the tension.
