Why We Like The Tempest 20L Backpack

For a day tearing up trail, we strap on our Tempest 20L Backpack. The adjustable harness system and hipbelt keeps our load stable without losing flexibility, so we can move freely while rock scrambling and weaving around switchbacks. The breathable backpanel and spacer-mesh material helps keep us cool while we test our grit.

Nearly Perfect - lots to like

I've used it several times
Size Bought:
5' 3"

The Osprey Tempest 20L pack replaces a 25L pack from another manufacturer. I really like the 2 hip-belt zipper pockets, the ability to quickly stow my hiking poles while on the go, and this pack seems lighter than my previous one. I'm short but have a long torso so I purchased the M/L. It fits well, and I really like the ventilation provided by the AirScape back panel. However, there are 2 things that are just "meh". As others have noted, it's difficult to get a filled 3L water bladder into the space in the back. If I only fill my bladder to 1.5 L, I can wiggle it in, but a full 3L is more problematic. For shorter hikes, I put 2 water bottles into the side stretch-mesh pockets. But these pockets seem to be further back than my previous pack, and it take a little arm twisting (or twisting the pack around) to successfully retrieve the water bottles. Otherwise, I really like the pack and have enjoyed using it.

Perfect daypack!

I've put it through the wringer
Size Bought:
5' 4"

After several months of use, I finally wanted to leave a review. I love this pack! It's perfect for a day hike and I love the positioning of the cross body buckles tailored for women (no straps across the boobs). It's super comfortable and holds a good amount of stuff on a hike. Very durable - I've brought it hiking, airplanes, cities, raft trips and more and it's held up perfectly. Lots of pocket space for stuff as well along with the large main pocket. I really like that you can put a water pack in too, although not included. I've recommended this pack to several friends because of how much I love it!

Tempest 20 is perfect daypack

I've used it several times
Size Bought:
5' 5"

This is my second Tempest 20. It is a great daypack--extremely lightweight and comfortable, with an adjustable panel on the back for various torso sizes. I have noticed that the water bottle holders on the sides are "taller" than the previous version, which is an improvement. (I lost a few water bottles when they were too tall and fell out.) This will accompany me for several years! I am 5'5", and the M/L fits great.
