The HAJKER ULTRA is the perfect pack if you’re looking for a high-end, low weight adventure pack for high-speed action. The backpack is designed for running with a load of up to 8kg and with the needs of on-the-go access to your essentials. The pack is developed in close cooperation with our adventure racing team and the prototypes are proven in the most grueling endurance races in the world. The features are made with extreme requirements to be perfect for any adventure.
Designed for extreme multi day adventure racing this fastpacking pack knocks out the competition in any light weight adventure. The Hajker Ultra is a 30L roll top with main fabrics made from recycled materials. The pack is equipped with our bounce free No Dancing Monkey™ 3.0 harness system which provides the best fit and comfort of any pack. The waist support belt provides 2 generous pockets with a construction where ventilation is prioritized as well as provided. Behind the pockets there are 2 other mesh pockets intended for easy access of 2x750 ml bottles. The sides and back of the pack provides mesh pockets for pretty much any need for a trail runner, fast packer or a mountain biker. With its ventilated and fixed back panel, this pack is easy to match for an individual fit and performance.
In 2019 the USWE Adventure Team claimed 1st position in the World Series Race in Croatia using two different prototype backpacks that where eventually released in 2020 as the Hajker 30L and the Hajker PR0 30L.
For the 2022 race the team were testing two new packs, one of them being the Hajker ULTRA 30L. Designed for the most extreme adventures with features that are specific for the long race needs.
“When we design our packs the most important feature is to make the packs suitable for actual running. Not just hiking… If the packs perform with 8kg of weight while running, the pack will work for any activity. The stress and the bouncing when running in the mountains is the best test for any pack”
- Jacob Westerberg CEO of USWE and team captain of USWE Adventure Team.

The back zippered pocket can be opened and closed while still wearing the pack, providing access to your head torch or your sun screen. Easy and fast. The side pockets on the waist belt is intended to store snacks and food and is also easily accessible as well as the water bottle mesh pockets on the sides. The later can be maneuvered with loading and unloading while on the go. With one hand. The back side mesh pockets can preferably be used for trekking poles that can be secured by using the compression straps on the sides. The mesh back pocket is generous enough for storing your freeze dried food or for just storing your jacket.
The side zippered pocket is a secure pocket intended for access of your first aid kit. Behind the back panel you will find a zippered pocket with a tube port, especially designed for a water bladder. The harness is equipped with the No Dancing Monkey technology including the USWE center buckle as well as side stretch. Wear the buckle closed when in action and open when relaxed. The harness also comes with attachment points for all of our NDM 2.0 accessories like phone pockets and action camera harness.

Thermo Cell is equipped with a multilayer insulation cover that reflects the heat on the inside and shields from the cold and wind from the outside. By its design, the Thermo Cell closes tightly to the body and a thin mesh membrane permits maximum body heat to pass through. Used in this way the body heat feeds the Thermo Cell with thermal energy. Smart!
Thermo Cell encapsulates heat from physical activity in an insulating air pocket that protects the tube and bite valve from freezing even in the most extreme winter conditions. Therefore, we have chosen to provide both shoulder straps on the NORDIC, HAJKER, POW and BRANT backpacks with Thermo Cell so that you get the option of choosing which side you want to have the tube in tube, or having tubes on both sides (double hydration bladders). Or optional, why not store gels and bars that you easily reach on-the-go in the pocket you don't use.
Its the unique shape and suspension of our No Dancing Monkey™ (NDM) harness systems that make our packs 100% bounce free. The construction allows you to snug the packs really tight to the body, without affecting your breathing capacity or body movement. Its almost like wearing no pack at all!
