USWE (pronounced - YOU-SWEEE) makes one thing: phenomenal product. Lately, if you've been paying attention to some of the racing scene, you've seen these on some world-class athletes crushing events like Leadville 100, UNBND Gravel, or SBT GRVL.

USWE makes bounce-free action packs that provide the perfect fit on an individual level – developed and tested together with top athletes, pro mountain bikers, and core weekend warriors since 2007. Their mission from day one is to design packs that you can wear in action with a super-snug race fit.

Why is this pack different?

The Hajker Pro Winter 30 is a step up from the Hajker line of weatherproof daypacks. While this one is still built for high-speed activities and rugged expeditions, it has a major winter upgrade. It features the same rolltop opening and is constructed from the lightweight yet incredibly strong ROBIC + UHMWPE EXTREEMA NYLON fabric, ideal for extreme conditions.

The upgrade? It has the added Thermo Cell technology to keep your fluids from freezing, by recycling your own body heat.

Equipped with the No Dancing Monkey™ 2.1 harness system and Snug Me waist support belt, this pack stays securely on your back without sacrificing comfort. Its ventilated back panel is easily adjustable for a personalized fit, making it perfect for those seeking a high-quality adventure pack for fast-paced action.

Highlights:

30L total storage
3.0L / 100 oz (Bladder not included)
Zero bounce w/ The No Dancing Monkey™ 2.1 + Snug Me Harness
Thermo Cell – anti-freeze insulation technology uses your body heat to protect the drinking tube from freezing.
NDM Buckle – technical buckle for a more secure closure and a better fit.

Waterproof – Rolltop opening and removable waterproof dry bag
Super durable ROBIC + UHMWPE EXTREEMA NYLON fabric

How do I use it?

On bad weather days when you need a daypack that provides protection, storage, and enough stability to get you through the backcountry.

How do I find my measurement?

With the NDM 2.1 harness we measure the size by using the "Torso Size" Measurement. It's actually it’s super easy to make your own size measurement and check if a pack works for you. All you have to do is measure your body height from your hip bone to your shoulders/collarbone (See picture below).

Torso Fit Range
