## Our verdict

### Reasons to buy

-   The harness system which also features lift-loaders is truly comfortable to use as it distributes the loads evenly without ventilation to your back.
-   Offers great organization throughout the entire bag.
-   The stowable helmet holder where you can dock your helmet or some other things during your activities.
-   SAS-TEC back protector decreases the chance of injuries that you may acquire in accidents or falls.

### Things to consider

-   Can be quite heavy for its size.
-   The back protector can be uncomfortable for some people.

## Reviews from around the web

**KIT REVIEW: DEUTER BACKPACK ATTACK 20**
[www.skedaddle.com](https://www.skedaddle.com/blog/kit-review-deuter-backpack-attack-20/)

> This is a great pack for carrying big loads in the mountain on demanding trails, allowing you to carry lots of gear in well-organised comfort. It is not however the pack I would reach for when heading out for a quick local spin due to its weight and bulk.’

**Deuter Attack 20**
[backcountry-expeditions.com](https://backcountry-expeditions.com/tests-and-reviews/deuter-attack-20-2/)

> There really isn't much to complain about with the Deuter Attack 20; Despite the back protector, it is pleasantly comfortable to wear and offers many functions.
