GORUCK X CARRYOLOGY ULTRA GR1
Kaidan 1.0 and 2.0 were and are still amazing collections. For v3.0 ULTRA, our aim was to improve upon both collections. “Ultra” comes from the Latin word “beyond”, and essentially translates to “greater than”. Executing this literally would be the goal.
We worked with the experts over at Challenge Sailcloth’s R&D department who took the UHMWPE (Dyneema) fibers, bundled them up into strands, then actually wove them together. Weaving the UHMWPE allows it to look and feel and perform similar to your common nylon fabrics we’re all used to... but outperforms nylon in almost every possible technical measure. We opted for the ULTRA 400X variant. “At just 3.5oz/yd2, it far exceeds the technical properties of any similar weight fabric available on Planet Earth”. ULTRA is the strongest material on earth. Backed by science and proven out in the field.
Kaidan v3.0 ULTRA is a selection of Carryology reader and team favorites, GORUCK best sellers, and Carry Award winners. While the GR1 is a fantastic everyday carry pack, it also makes for a fantastic minimal travel pack. Carryologists have been using the GR1 to travel the world for over a decade now, so this was an easy addition to the Kaidan family. Bonus, you can use it for EDC too.
