Siouxon A.M. 15L Backpack

Strap on the Platypus Siouxon A.M. 15L Backpack and head out for a ride, because it's got everything you need to enjoy a day on your bike. This low-profile pack is the larger option for the Siouxon, and features plenty of bells and whistles, including a 3L hydration bladder, gear-specific pockets, and an incorporated rainfly in case you encounter stormy weather. The FloatAir back panel is made from a highly breathable mesh that's tensioned over a wire frame, keeping support up and weight down, all while optimizing cooling airflow as you ride. Platypus being Platypus, they naturally want to keep you hydrated—they equipped the Siouxon with easy hose routing and magnetic hydration retention, so a refreshing sip is never far away.

Almost perfect!

True to size
5` 8"
140 lbs

This fits the best out of any pack I've ridden with and doesn't bounce around on descents! There's plenty of room inside to pack for long rides but it also compresses to be fairly small (the top still poofs out) if you're not bringing much. The only thing I could see being an issue is the hip strap with pockets (yay) is rather large and at 140lbs I almost tighten it all the way (there's maybe an inch on either side) so if you're smaller you may not be able to tighten it as much as you'd like.
