    The  Mountain Series  is a hand selected collection of the  highest performance fabrics/materials on earth  - each one optimized for applications ranging from tarp/shelters, to quilts, hammocks, packs, and other high-end outdoor gear. 

    Custom woven from the ground up with high-tenacity nylon 6.6 yarn and an  oversized ripstop grid1.3 oz MTN XL Hybrid sets the new standard for ultralight fabric in strength and durability. 

    Compared to our previous generation 1.2 oz variant, 1.3 oz MTN XL is:

    • Roughly 30% stronger (*based on tear strength ASTM D1434)


    • Higher abrasion and UV resistance (*via upgrade to HT nylon 6.6)

    As the name implies, 1.3 oz MTN XL Hybrid uses our unique Hybrid weave ripstop construction. Compared to most standard ripstop fabrics, we use a much  thicker, stronger yarn (80D) for the ripstop grid vs the base fabric (20D).

    The result is a noticeably stronger and more rugged material with minimal increase in overall finished weight... 

    MTN series Hybrid ripstop weave

    Lastly, we utilize a diamond hybrid ripstop grid pattern. This makes the fabric easier to sew, increases comfort for load bearing applications (e.g. hammocks), and tends to  extend the overall life of the fabric

    Like the other fabrics in our XL line, we've custom woven 1.3 oz MTN XL Hybrid to be WIDER than standard fabrics at 68" versus the more common 60" width.

    Typical uses include widebody hammocks, synthetic quilt shells, chairs, light duty bags, or any application where breathable and lightweight yet strong/durable fabric is needed.

    NOTE - This fabric was transitioned to 1.3 oz nylon 6.6 from the previous 1.2 oz nylon 6 variant on 7/30/19. The 1.2 oz nylon 6 variant will not be restocked. Thanks!

1.3oz MTN XL hybrid ripstop nylon 6.6

Nice product to work with. I used this for a hammock project it is very light but yet seems very durable. Will be using again in the future on other projects.

RSBTR for another great product.

1.3 oz MTN XL Hybric

Purchased on the first day of release! Made a hammock for my brother as I wanted to make him something unique. The new material was very easy to sew (very stable in all directions/planes). Not too stiff, but not as "buttery" as HyperD. I do appreciate the weight savings and the large format (my 6' 3" brother will too).
Thanks RBTR!

Great stuff delivered fast!

Exactly what I ordered delivered quickly.

1.2 MTN XL Hybrid

I have tried a number of fabrics from RSBTR and others. I find that I like a fabric with less stretch i.e. 1.7 Robic. However the 1.2 MTN has a nice amount of stretch but still feels solid. After several years working with RSBTR, I feel I don't have to talk about their service, quick delivery times or variety of products. You can find glowing reviews everywhere for this company. Because they are great.... at everything. Back to the fabric, it holds a crease well, feels tough for a UL fabric and moves nicely under the ol' feed dogs.

Lighter chair

Used this to replace the material on my Helinox ground chair, worked great, easy to sew and appears very strong! My chair is now 173 grams or 6 oz lighter! Love it!

Hi Rick, The 1.2 MTN series is a great material, and we're glad we were able to help bring the weight of the chair down. Thanks for the review!
