The women’s-specific Osprey Tempest 40 is the perfect choice for an overnight adventure or a long day hike.

This pack has a peripheral aluminum frame that transfers the weight of the load evenly across the Airscape™ mesh backpanel to keep you cool on the trail. The BioStretch™ shoulder harness and hipbelt are easily adjustable for all-day comfort. InsideOut™ compression straps add stability when you’re negotiating rough terrain.

Inside this top-loading pack, you’ll find a sleeping bag compartment to keep your bag safely stowed. The removable lid has two zippered pockets to keep small items organized. You can stash more small gear in the two mesh side pockets and tuck an extra layer in the convenient mesh front panel. The hipbelt has two zippered pockets to secure a camera, phone, or trail snacks. And there’s an external hydration sleeve for easy reservoir refills.

Also on the exterior, you’ll find Osprey’s Stow-On-The-Go™ trekking pole attachment system and a pair of ice tool attachment loops to hold your sticks and picks when you don’t need them.

Comments about Osprey TEMPEST 40:

I love the size and weight of this pack! I have worn the pack nearly everyday for a month doing shorter training hikes and I love it. I am preparing to hike 500 miles on the Camino de Santiago with a 13 pound pack (not including water). This pack is just the perfect size for my minimalist gear. It also adjusts perfectly and is very comfortable and lightweight. Know that the side mesh pockets have openings on the sides so any loose or small items will fall out, but they are great for a water bottle or bulkier items (hat, gloves). The small pockets on the waist belt are really too small to comfortably fit an i-phone 5s with a case or larger phone. I wish there were at least one secured (zippered) pocket on the outside. For a rain cover, the small (35L) Osprey high visibility cover fits perfectly. The 1.5L Osprey water bladder fits just right.
