The Big Stuff Sack is large enough to hold my overnight camping clothes down to freezing temperatures and fits perfectly sideways in my Arc Haul Zip. While it doesn’t have a dry bag closure, I think it would provide protection from bladder or other leaks inside the pack.

– Doug L., ★★★★★

This big sack will fit multiple clothing items, larger tents, bigger sleeping bags, or other soft bulky items. This stuff sack is spacious but still lightweight thanks to the Dyneema® Composite Fabric construction. It will fit well horizontally in larger backpacks.

  • Constructed from Dyneema® Composite Fabric in several choices of fabric weight.

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

  • Stuff sacks can easily be patched with Dyneema® Composite Fabric Repair Tape.

  • 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

.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.

Stuff sacks

Bought a few stiff sacks to shed unnecessary weight. Super light dyneema and quick ship. Thanks z-packs!

Awesome stuff sack!

I love the Dyneema stuff sacks. They weigh next to nothing, fit in the palm of your hand. The pull cord slides so smoothly, unlike some nylon stuff sacks I own. I really like the roll top sacks Z Packs sells . I will not buy a nylon stuff sack ever again. Z Packs has never disappointed me they make awesome gear, and knowing my money is going to a small company is a huge plus for me. F big corporations!!
