Osprey Syncro 15
In hot temps, this pack kept us coolest, thanks to max airflow across the back.

V-shaped “baffles” inside the 2.5-liter reservoir minimize slosh. A hose quick-release at shoulder level allows for easier refilling and keeps working parts outside the bag; if there’s a leak, you’ll catch it fast. A shoulder strap magnet keeps the hose in place, but the bladder constantly slipped off the rudimentary hook meant to hold it.
A trampoline-style, mesh backpanel supports loads up to 15 pounds with minimal sway. The yoke-like shoulder straps distribute weight evenly across the back.
Two front pockets keep gear well organized. A bungee on the front accommodates a helmet and a polyester-lined pocket holds glasses without scratching. Bonus: an integrated rain cover.
The trampoline-style suspension provides excellent air circulation, and plentiful slots in the foam and mesh shoulder straps enhance airflow.
