The women’s-specific Osprey Tempest 20 is designed for high-speed action—either on foot or on two wheels. Quick access this pack comes via a zippered front panel that allows you to see all your gear at a glance. And the LidLock™ helmet attachment system gives adventure racers and cyclists an extra edge when every second counts.

This pack has a peripheral framesheet to transfer the load evenly across the Airscape™ mesh backpanel and keep you cool on the trail. The BioStretch™ shoulder harness and hipbelt are easily adjustable for on-the-go comfort. InsideOut™ compression straps add stability when you’re negotiating rough terrain at speed.

Shave a few seconds by using the zippered slash pocket, two mesh side pockets, or the convenient mesh front panel to quickly stash small gear you want to keep handy. The hipbelt has two zippered pockets for fast access to a camera, GPS or trail snacks. And there’s an external hydration sleeve for rapid reservoir refills.

Also on the exterior, you’ll find Osprey’s Stow-On-The-Go™ trekking pole attachment system and an ice tool attachment loop to hold your sticks and pick when you don’t need them in your hands.

    Comments about Osprey TEMPEST 20:

    I went on a day hike with a friend who had this pack and started coveting it pretty much once we got out of the car. 9 miles later I knew I wanted one of my own! I have used it several times and love it! The straps are lightweight and breathable but still soft and comfortable. The waist pockets are stretchy and fit my iPhone 6s easily (even in its LifeProof case). My Osprey 2.5L hydration bladder fits easily in the back and the side mesh pockets fit my 1L Comeback and Nalgene bottles. There are several smaller pockets to hold keys or snacks or sunglasses or whatever small items you might want to keep separate from the main contents of the pack and the trekking pole attachments are very handy especially when the hike requires scrambling over rocks. I got the gray/light blue color combo and think it looks really nice!
    I haven't used the helmet attachment for a helmet yet but its great for attaching a small hand sanitizer bottle to!
