If you're looking to save a bit more, the Trekology Trek-Z 2.0 is a decent option, although it's not as well-constructed as the Legacy Lite
Osprey packs like the Exos and Eja packs do well in these areas, although the Hyperlite Mountain Gear, and Z-Packs also do well and weigh less
Alternatively, some packs (like the Osprey Aura) feature suspended mesh back panels and hip belts that cradle the body while maintaining ample airflow
