The Osprey Kestrel 28 daypack is ideally sized for multi-sport activities including day hiking, mountain biking, and rock climbing. It has ample internal and external storage providing great flexibility and an adjustable frame, making it ideal for newer hikers who don’t have the experience required to properly size a backpack with a fixed-length torso.

Frame and Suspension
The Kestrel uses Osprey’s adjustable Airscape frame and suspension system. This includes a ridge molded foam backpanel covered in mesh, providing good ventilation and a-close-to-your-back fit and superior lateral control.
An adjustable torso yoke system is connected to the shoulder straps and slides up and down in the space behind the back pad. The yoke is a tongue-shaped piece of nylon with strips of velcro along its sides that attach to velcro located on the rear of the back pad. This allows the height of the shoulder straps to be raised or lowered depending on your torso length. See the winged symbols (above) which are used to measure additional torso length.
Once set, the adjustable torso does not budge – amazing the holding power of velcro! However, when adjusting the torso length, care should be taken to make sure that the shoulders are set at a level height for maximum comfort.
In terms of capacity, the Kestrel 28 is a good size for carrying the 10 Essentials with plenty of room for food, water, and the comfort extras you like to bring along on a hike. Most daypacks are sized in the 20-liter to 30-liter range for this purpose.
The Kestrel 28 has 3 external mesh pockets for stowing all the gear you need fast access to during a hike or drying out wet gear separately from dry stuff. Personally, I always pack snacks, water bottles, my rain gear, and map in such external pockets so I don’t have to dig around for them in the main body of the pack when I stop for a quick break. All the other stuff I bring along that I’m likely to not need, goes into the main compartment, out of the way.
In addition to the mesh pockets, the Kestrel 28 also has a top lid with a zippered pocket, that covers the drawstring closure of the main compartment. It’s not huge, but large enough to carry your keys, wallet, and items that you want to know are secure. There’s also a mesh pocket under the lid for additional storage.
If you prefer to carry a hydration bladder instead of water bottles, it can be inserted in a space between the main body of the pack and the back of the shoulder harness (as shown above). This makes it easy to pull out when it’s empty, but is still a challenge to reinsert if your pack is full. Storing a full hydration bladder in this location also has a tendency to create a bulge behind your shoulders, which I find uncomfortable -another reason why I prefer to carry water bottles on the sides of a pack in mesh pockets.
The Kestrel 28 comes with a number of additional features that provide excellent value for a pack in its price range. These include:
- Dual ice axe loops with elastic keeper straps for ice climbing
- Two tiers of side compression straps for securing additional gear to the sides of the pack.
- Integrated rain cover, hidden away in a rain cover pocket.
- Extra tie out points on the rear of the mesh pocket to strap more gear to the back of your pack
- Ergo Pull hip belt system providing excellent hip support when properly fitted over your hip bones.
The Osprey Kestrel 28 is an excellent daypack that has the capacity and flexibility to support many different kinds of all-season backcountry adventures. Though small in size, this pack is loaded with the same features that you find on larger overnight and expedition backpacks, like the venerable Kestrel 48 and Kestrel 38 from the same Osprey pack family. The only issue I have with the Kestrel 28 is the size of the hip belt which is too short (even in a size M/L) for anyone with a waist-size over 38″. Otherwise, the adjustability of the torso length on this pack is a huge value-add at such a low price point, making this a great pack for the money.
