Prometheus Design Werx

Purpose-Driven & Multi-Use Design

The W.ilderness U.tility U.rban L.ay design is a modern interpretation of the classic, alpine style, top-loading summit assault pack.

Built for Multiple Environments

Designed and built for use in the wilderness and backcountry, with features for urban use as well. This pack’s numerous considerations make it a versatile, modern-day tripper for today's backcountry, trails, a bike run to the grocery store, or a day at the office.

Premium Materials

The W.U.U.L.F. Pack is built with 500D Cordura, a material that has proven to be a great balance of life-long durability and lesser weight. The W.U.U.L.F. pack was constructed to handle the rigor of the day in and day out use in multiple environments.

Versatile Performance

The W.U.U.L.F. Pack 24L, like our S.H.A.D.O. Pack 24L, represents a lifelong, yet constantly evolving core design ethos and aesthetic seen throughout all of our PDW products. The DNA of the W.U.U.L.F. Pack 24L can be traced to the classic design and engineering lineage of the core outdoor and alpine sports tradition. Versatile and modular pack accessories are available for you to customize your pack to suit your needs, for your one day 12 miler, a trip to the local crags, snowshoeing, to an evening of food truck crawling, or a day's worth of work stuff.

Designed to Last

To address the less durable stretch fabrics used for most packs' water bottle pockets, we introduced a new double-gusseted design using the 500D and adjustable shock cord. And should the cord elastic ever blow out, it is user replaceable.

We chose to use alloy tension hooks for the top lid closure and compression straps at the request of several climbers we know. The rationale was that the main point buckles wouldn't be vulnerable to cracking, like the nylon or acetal type, if stepped on with rock underfoot when the pack was on the ground.

Wilderness Utility Urban Lay Flat

The W.U.U.L.F. Pack 24L gets its name from it’s unique feature of a center front 2-way zipper. This style zipper opening allows a secondary B.E. access/entry point into the main compartment with the top lid closed, and when the top lid is opened and laid flat on any suitable surface, can be fully zipped opened to allow access to nearly 90% of the main compartment.

Characterized by classic looks and possesses numerous modern considerations inside and out.

Seems solid

It appears to be built with quality materials. I'm using it for an overnight bag soon with a complete change of clothes, large toiletries bag and hiking boots currently. A few more small pockets would be nice, and asbI read about another similar pack, it seems a bit more intuitive (to me) if it was wider towards the bottom, not the other way around

Fantastic all around pack

I’m loving the WUULF
I’ve used it on hikes, as a gym bag, and on a small vacation. Being able to remove the waist belt and the top cover makes it very versatile. It’s a home run for me.

Wuulf 24

I like this pack quite a bit. It's got a couple of long day hikes on it already. Carries and balances really well. Top pouch inside pouch is great for the small essentials, and the outside top pouch is great for the quick grab stuff. Really well thought out. Swapped the laptop pouch to a shado pack, and the molle organization panel went in this one.

Great bag but not perfect.

Absolute love this bag and highly recommend it! However, there are areas that could be improved upon to make it a PERFECT bag.
1. Side pockets for water bottles are way too shallow. My bottle keeps falling out even with the bungee cord straps.
2. The velcro straps for trekking poles in the front of the bag are way too short to attach anything there.
3. The belt strap is weakly attached to the bag by a thin strip of velcro to keep it in place.
4. Adjustment straps by the top of the shoulders are weirdly made because cinching the straps create huge strap loops that appear to be strangely out of place and in your face.
5. I have difficult time adjusting any straps that are attached to plastic buckles. Straps that attached to aluminum buckles are easily adjustable.
6. This is my personal preference, I would love to see the hood to be detachable and made slightly bigger than the current state to match the size of the bag.

Good solid pack!

This is a good,, well-designed pack with many thoughtful features! Used it recently on hikes in the Pacific Northwest at Olympic NP and Mt. Rainier. The zipper and top opening are great for accessing gear, the waist belt and straps are very comfortable, and the pack held up well. Carried a 2-L hydration bladder, rain gear, cameras, etc. totaling about 15-20 pounds.
