Ultra PE Dry Bag – Double Opening

(2 customer reviews)


A dual entry waterproof dry bag made from Ultra PE fabrics (Ultra high molecular weight PE, branded as Dyneema® and EPL from EcoPak™). Add our Armadillo protector to improve your dry bag’s abrasion resistance.

Size Small is best for riders looking for more tire clearance (e.g., bikes with front suspension) and low volume sleep kits (e.g., summer sleep systems).

Our Ultra PE Dry Bag offers a lightweight dry bag solution with a double roll, giving access at both ends. We like to use the double roll for storing our sleeping kit in the middle with clothes at one end and our puffy coat at the other end (for easy access during the day).

The profile is also what we consider a “slim-fit”. This allows the dry bag to tuck more easily under cables and nestle under your handlebars. When used on a handlebar roll the slim size provides more clearance for bikes with front suspension. Check our Bikepacking.com's first look along with our Armadillo dry bag protectorThis dry bag has a single seam down the center that is sewn, then taped twice with Dyneema® tape to ensure a waterproof seal.

25" Voile straps are the ideal length to wrap around the Ultra PE Drybag.

    I recently picked up the Ultra PE Dry Bag to use on a few bikepacking trips this past summer in the PNW. Like others, I have different mounting options across my bikes, so the Ultra PE Dry Bag works well with my front rack (a Tumbleweed T-Rack). I purchased the Armadillo Dry Bag Protector as well, for the added protection against the off-road riding.

    This drybag combined with the Armadillo protector on top of my back rack is the “closet” of my set up. I got a whole sleeping bag (The low end, non tecnical kind) and the majority of my clothes into it. I recommend this product. It is also built tough, looks like these guys @ Rockgeist are in NASA lol.
