Sierra Designs Tensor 10 Rucksack

Jump to: Our Verdict / Features / Specifications

UOG TOP PICK – Tensor 10 Rucksack – Rab’s Tensor range of packs are aimed at day activities be it running, hiking or bike riding, they have a foam padded back panel that is sculpted to allow some airflow. We really like the large mesh pocket on the outside.

Rab says:

Hit the trail with the Tensor 10, a lightweight multi-purpose day pack suitable for hiking, cycling and running.

The Tensor 10 features the AirContour back system, with a pre-curved back panel that promotes a closer fit and more natural movement. A zipped top pocket and key clip keep valuables like wallet and phone safe, and for those quick early morning or evening sessions, a light loop and reflective graphics make sure you’ll be seen in the dark. Hydration compatible, the Tensor 10 fits a 2L hydration sleeve and has stretch water bottle side pockets. A front stash pocket gives easy access so you can grab extra layers or snacks on the move.

With a lightweight breathable back system and removable waist belt, the Tensor 10 is perfect for short hikes in the summer and mountain biking missions.

Our Verdict

Rab’s Tensor 10

Rucksack is one of a series of capacities in the Tensor range aimed at general purpose day use. The packs are very well made with a good feature set, we particularly like the wide opening and external mesh pocket on this model for stuffing the gear you need easy access to during the day although you still need to remove the pack to get at it.

Inside there’s a bladder pocket and a zippered mesh pocket for small stuff, and a similar pocket accessed from the outside. There’s only one bladder outlet and that would bring the tube out over the right shoulder.

The back panel is foam to keep the contents from poking through and is grooved in an attempt to get a bit of venting on the back. It’s not stiffened but you wouldn’t really expect that on a rucksack without a hipbelt – the Tensors have a strap that acts as a stabiliser rather than an out and out hipbelt.

It’s a nicely finished pack but there are a lot to choose from in this category.
