Osprey Helios 20

I have tried many different brands and models of daypack and this one is #1 . The Helios 20 is a very form fitting and compressible pack with many of the extras that most smaller packs leave to their big brothers.

The Helios 20 has a hydration sleeve and port along with a large main zippered compartment. A smaller zippered compartment is located on the top of the pack with plenty of room for your wallet, keys, flashlight, and a few energy bars. There's also a pocket on the side of the pack big enough for a small water bottle etc.

The harness is fully adjustable and the front of the pack has a large mesh pocket and lashing bungee. With six compression straps and two accessory loops it's hard to believe this pack only measures 18"L X 12"w. To say this pack is packed with features is an understatement.

If you're looking for a daypack, trail running pack, or mountain biking pack. Give the Helios 20 a try.
