BIGGER DITTY

Not sure which fabric to choose from the available options? Here's a quick guide on the differences.

If weight of the bag is your biggest concern, then Ultra TX70 and UltraGrid will be your best option. If a bag with more structure and "body" is what you're wanting, then X-Pac RX15 and RX30 would be a better choice.

Challenge Outdoor UltraGrid, UltraWeave & Ultra TX70:

A solid, lightweight and super strong fabric. UltraGrid is a 100% recycled nylon that's 210D and features a double Ultra fiber ripstop that makes it incredibly strong, and nearly impossible to rip. At 146 gsm, it's a touch heavier than Ultra TX, but offers more color options. UltraGrid is a single layer, woven fabric. It's a Backcountry Exposure favorite.

The ultralight hiker go to. Ultra TX70 is a 3 layer laminate with a 70D polyester ripstop face fabric, crossply ultra fiber and PET film that can be seam taped. It's lighter weight at 99 gsm and is ideal for when grams count.

For maximum durability the UltraWeave 400X fabric is excellent. UltraWeave is also laminated and features the strong Ultra fiber that's highly abrasion resistant while also being lightweight.

X-Pac RX Fabrics:

X-Pac RX15 is a 3 layer laminate fabric that's 100% recycled polyester with a 150 denier face fabric. It has a nice, soft hand feel on the face fabric. It's a touch heavier at 196gsm but is incredibly durable, has great structure and very durable for the weight.

X-Pac RX30 has the same 3 layer construction as RX15 but features a 300 denier face fabric and more color options. For maximum durability and structure on the bag, go with RX30.

Other Fabrics:

X-Pac VX07 features a 70 denier face fabric that's laminated to a 70 denier taffeta liner. It's lightweight, strong and built to last.

Challenge 450RS is a 450 denier, single layer ripstop recycled polyester bag cloth. It's PU coated inside and has a C0 DWR on the outside. A bit heavier weight, but strong and durable.

Backcountry Exposure bags are highly water resistant. All of the fabrics used on our bags are waterproof through environmentally friendly PU and DWR coatings, or lamination.

Bags that use a zipper for the opening are not seam taped or sealed.
Roll Top bags without a zipper ARE seam taped, like the Aven Roll Top Food Bag.

Why do you not seam tape/seal all of your bags?
Seam sealing adds significant time and cost to production and in many cases, sealing isn't necessary for the function of the bag. Our bags will resist water from a light rain and keep contents dry. Any gear items of concern in getting wet should be placed into a dry bag that's designed to be 100% waterproof.

Bags can be seam sealed or taped by you should you decide to do that yourself.
