  • The side seam is taped for strength but these should only be considered water resistant due to the draw cord opening.

  • Also check out our Dry Bags for a slightly heavier, but more abrasion and water resistant way to protect your critical items from the elements.

.55 oz/sqyd Standard Dyneema® Composite Fabric

Dyneema® Composite Fabric is composed of high strength Dyneema® fiber laminated inside a polyester membrane. It is inherently waterproof and does not require any coatings or DWR treatment. Dyneema® Composite Fabric has very high tensile strength for its weight and does not stretch.

.55 oz/sqyd Dyneema® Composite Fabric is our lightest weight version. It has high tensile strength, but only moderate abrasion and puncture resistance due to the thin membrane material. All colors are light and semi see-through.

Available in Blue, Olive Drab, and White.

Tensile Strength:
 63 lb/in (552 N/5cm)

Puncture Strength: 
1.8 lb (8 N)

Water Resistance:
 15,000 mmH₂O

Made in the USA.

.66 oz/sqyd Dyneema® Composite Fabric

This material choice has the same Dyneema® thread count as standard .55 oz/sqyd, but with a slightly thicker laminate that allows for a darker color or pattern to be printed on the material. The thicker laminate brings the fabric weight to .66 oz/sqyd.

Available in Camo Print.

Tensile Strength: 63 lb/in (552 N/5cm)

Puncture Strength: 1.9 lb (8.5 N)

Water Resistance: 15,000 mmH₂O

Made in the USA.

.75 oz/sqyd Dyneema® Composite Fabric

This version of Dyneema® Composite Fabric has a higher Dyneema® thread count which gives it an additional tear strength and abrasion resistance.

 104 lb/in (911 N/5cm)

Puncture Strength:
 3.1 lb (14 N)

Great light bags

Great, use all the time for everything. Little expensive, but even ultra sil bags are close in price and these are way tougher while being way lighter

Awesome stuff sack for revelation quilt

This is q great stuff sack for the enlightened equipment revelation 30 degree quilt. I though it would be too small for it, but once I tried it was relieved that it fit perfectly.

Torn stuff sack

I loved my first experience with the duplex, but when I was putting it in the stuff sack the next morning the bottom of it split apart. I emailed zpacks when I got home from my trip and they got right back to me to let me know they were dropping a replacement in the mail. It took a few weeks to get here, but they warned me that would be the case so it wasn't a problem. Overall, I was very pleased with the product and the service. Thanks!

Whoa, light as a feather!

Actually haven’t used it yet. But it looks sexy and is incredibly light.
