PINNACLE OF ULTRALIGHT PACK DESIGN:
The updated Ultra 200X & UltraGrid Kakwa 40 boasts a larger front pocket (nearly 2x volume), drain holes, custom Durston Gear logo buckles, additional lash points, and a variety of small refinements to further improve durability. The Kakwa 40 design is informed by Dan’s thousands of miles of backpacking experience, resulting in best-in-class load carrying, usability, quality, and durability – all while weighing a mere 28 oz / 795 g (ULTRA™ 200X) to 29.6 oz / 841 g (UltraGrid) for a medium pack.
LOAD CARRYING AND COMFORT:
The Kakwa 40 uses an inverted U-shaped frame built of hollow aluminum that is a more efficient use of structural weight and provides a rigid core with both vertical and horizontal structure. This frame connects directly to the hipbelt for optimal load transfer and directly to the load lifters, which are rare on packs this light yet essential for shifting more of the weight off your shoulders. Carefully developed S-shaped shoulder straps contour around your upper body, while the hipbelt uses a dual strap design to cup your hips and has reverse pull leverage for easy tightening.
The result is a pack that comfortably and effectively manages loads up to 45 lbs, all while weighing just 28 oz / 795g (Medium / Ultra 200X) to 29.6 oz / 841g (Medium / UltraGrid).

CHALLENGE ULTRA™ 200X – THE ULTIMATE TEXTILE:
UltraGrid is a nylon-based pack fabric that features a ripstop grid of UHMWPE fibers for added durability and a waterproof PU coating. This fabric offers a smoother feel, a tighter weave, and a more affordable price point.
In a class of its own, ULTRA™ 200X represents a new paradigm in durability and weight. ULTRA™ 200X weave is constructed with an optimal blend of UHMWPE & high-tenacity polyester. The tight weave is laminated with an eco-friendly adhesive to their revolutionary Challenge RUV™ film. The result is a textile that is incredibly strong, lightweight, and waterproof to 200 psi. The updated "X" version incorporates a tougher inner film for added durability.
Simply using a tough fabric is not enough if the pack has weak points in the stitching or supporting materials. That's why the Kakwa 40 is fully double stitched with heavyweight thread, and features the same ULTRA™ material for heavy wear points like shoulder straps, hipbelt pockets, and sided pockets. The front pocket is composed of durable knit mesh that won’t stretch out.

EFFICIENT POCKETS:
Efficient access to your gear while on the move is a hallmark of good pack design – and the Kakwa 40 delivers. Collectively, the Kakwa’s suite of pockets is carefully thought out and refined to enable rapid and efficient access to everything you need on the move. Four types of pockets optimize on-the-go access to most essential items:
- Hipbelt pockets with a generous shape easily accommodating snacks, sunscreen, or headlamps.
- Dual top opening shoulder strap pockets provide an ideal spot for your phone, sunglasses, or bear spray.
- QuickPocket provides an easily reached, concealed compartment in the side pocket for large items like hats, mitts, or large sized phones.
- Mesh front pocket for largest items like jackets and even cookwear – Hike all day without opening your pack.
HIGH STANDARDS, WITHOUT EXCEPTION:
The Kakwa 40 is made in the epicenter of high-quality outdoor product manufacturing, home to factories that produce tents and packs for the top brands in the world. The factory that produces the Kakwa also produces some of its top competitors from well-known companies such as Arcteryx, maintaining the highest level of materials sourcing, construction techniques, and testing with all the packs it produces.

Would recommend
Size: 10 sqft
I used this sound deadening material in my car during an audio and interior upgrade, and the difference was noticeable immediately. Road noise, vibrations, and rattling were reduced a lot, especially on the doors and floor panels. The car feels much quieter and more solid while driving now.
The material was easy to cut and apply, and the adhesive stuck very well without peeling up. It has a quality feel to it and conforms nicely around curves and tight areas. I also noticed my speakers sound cleaner and have better bass response after installing it.
For the price, this sound deadening material is a great value and definitely worth it if you want a quieter ride and better overall sound quality in your vehicle.

Worth it!
Size: 50 sqft
I was worried it wouldn't work as well since it's 50 mil and I thought I got the wrong thing. Nope! Works great. Did all four doors on my 93 civic and I have enough for the floor I think. Solid price. Noise reduced by about 5 decibels hive difference. Very sticky and easy to apply I'm so happy I was able to cover most all of my car. If I need more, definitely buying this since I got so much extra and I thought I would.
PS: that five decibel thing is only with the four doors. My firewall is next and then my floor, but it's such a huge difference

Quiet your vehicle noises
Size: 50 sqft
Put this in our high roof van and couldn’t believe how much quieter it was at once. Really cut down on the vibration noise Nice and easy to install just peel n stick. Was also easy to cut with scissors for smaller areas. Seemed to be really nice quality. Didn’t notice any odor.
