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.

I think I'm going to love this pack

Haven't used this pack yet as my Zion trip isn't due for another 2 weeks. Heading to REI today for a 3L or so water bladder.
Got this pack a few days ago and I'm immediately impressed, obviously can't do a reliability review till the trip is done and a few hikes are under its belt.
I like the size, striking a balance between size, weight and durability is paramount in the pack world for the intended scenario.
I'll write another review in the future after I have some use out of it.

My first pack and just like everything else from PWD it’s rock solid. I don’t think there’s better out but as I said my first pack but I can tell it’ll stand the tests of time.

WUULF Pack Experience

I train dogs and hunt. I was looking for something in 25L neighborhood that could be a do-all bag, and this is as feature packed as is possible for the price point. My only big requests would be a non vertical zipper version, and metal buckles for the waist and chest strap. I don’t think there is a better bag at this capacity!

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.
