Cuben Fiber Roll Top Dry Bags


These stuff sacks are sewn "envelope" style with a taped seam down the side and across the bottom. The top of the bags roll down and clip together to keep out water. The roll top can also be used to compress the contents.
  • Constructed from black 1.0 oz/sqyd Cuben Fiber material. By comparison our regular stuff sacks are made from thinner .51 oz/sqyd material.
  • Fully taped seams. Our dry bags will keep water out in typical backpacking conditions where the bag is not submerged.
  • The top of the bags seal with stiff velcro to make closing and rolling the top easy!
  • Also check out our Zip Pouches for waterproof protection for your smaller items like your wallet, camera, phone, passport, glasses, etc.
  • 1 year warranty against defects in materials or workmanship on all ZPacks gear.

Small Dry Bag
This small dry bag is a good size for a small clothing item, or a handful of miscellaneous loose items.

Flat Dimensions: 8.25" wide x 11" tall  (21 cm x 28 cm)

Full Dimensions: roughly 5" diameter by 7" tall (13 cm x 18 cm)

135 cubic inches / 2.2 Liters
Small Dry Bag
weight: .6 oz. / 17 grams
price: $19
Slim Dry Bag
This narrow size might squeeze into your backpack's side pocket. The volume is about right for some clothing items, a small tent, or a small summer down quilt.

Flat Dimensions: 8.25" wide x 18" tall  (21 cm x 46 cm)

Full Dimensions: roughly 5" diameter by 12" tall (13 cm x 31 cm)

245 cubic inches / 4 Liters
Slim Dry Bag
weight: .7 oz. / 20 grams
price: $22
Tall Dry Bag
This bag is the same girth as our Slim dry bag, but 18 inches tall. It is a good size to store a tent or sleeping bag standing in a pack's side pockets. It will also fit well lashed with a backpack's base straps.

This size will fit our 20F (-7C) sleeping bag, or our Duplex or smaller tents. It is a tight squeeze in our backpack's side pockets but it does fit as shown.

Note that keeping a sleeping bag on the outside of your pack may not be the best idea since you want to make sure it stays dry no matter what. A tent on the other hand is no problem.

Flat Dimensions: 8.25" wide x 22.5" tall  (21 cm x 57 cm)

Full Dimensions: roughly 5" diameter by 18" tall (13 cm x 46 cm)

350 cubic inches / 5.7 Liters
Tall Dry Bag
weight: .8 oz. / 23 grams

Medium Dry Bag
This is a good size for multiple clothing items, a tent, or a down quilt. This size fits well horizontally in most smaller backpacks such as our Arc packs.

Flat Dimensions: 10.5" wide x 19" tall (26.5 cm x 48 cm)

Full Dimensions: roughly 6" diameter by 12" tall (15 cm x 30.5 cm)

Medium Dry Bag
weight: .85 oz. / 24 grams
price: $28
Medium-Plus Dry Bag
Another good size for clothing, sleeping bags, etc if the dimensions of your pack are a little larger. This fits well in our 60L and larger packs.

Flat Dimensions: 11.25" wide x 21" tall (28.5 cm x 53.5 cm)

Full Dimensions: roughly 7" diameter by 15" tall (18 cm x 38 cm)

580 cubic inches / 9.5 Liters
Medium-Plus Dry Bag
weight: .95 oz. / 27 grams
price: $30

Pillow Dry Bag
This dry bag is identical to the size Medium or Medium-Plus dry bags shown above, except it has soft micro fleece sewn to one half on the inside. Flip the dry bag inside out as shown and fill it with your spare clothes and gear to use as a pillow! The fleece is more comfortable on your face than the plastic feel of a normal stuff sack. It has the same normal roll top and the seams are all taped, as usual.

Tip: Use some self-adhesive Clips to attach your pillow to your sleeping pad.

Here is a Review.

Large Cylinder Dry Bag
This large stuff sack will fit horizontally in deeper, wider packs. Try the rectangular size below for smaller packs (all ZPacks packs fit the large rectangle size below better).

Flat Dimensions: 13" wide x 23.5" tall (33 cm x 60 cm)

Full Dimensions: roughly 8" diameter by 15" tall (20.3 cm x 38 cm)

This will fit a sleeping bag, a bunch of clothes, or use it as a food bag for about 5 or 6 days supply. The rectangle shape fits well in all of our backpacks, either standing vertically or sideways depending on the pack volume.

Flat Dimensions: 15.75" wide x 19.25" tall (40 cm x 49 cm)

Full Dimensions: 11" wide by 5.5" deep by 12.5" tall (28 cm x 14 cm x 32 cm).

weight: 1.2 oz. / 34 grams
price: $35
Roll Top Blast Food Bag
This stuff sack is the same size as the large rectangle above, but made with thicker 1.43 oz/sqyd Cuben Fiber fabric. The thicker material can stand up to the abuse of bear bagging heavy, pointy food items. A Free Carabiner is included for hanging the bag from the roll top!

These may be Blue, or Olive drab, instead of black like the other roll tops. There are two shapes to choose from.

"Rectangle": (Fits in all ZPacks size backpacks)
Flat Dimensions: 15.75" wide x 19.25" tall (40 cm x 49 cm)
Full Dimensions: 11" wide by 5.5" deep by 12.5" tall (28 cm x 14 cm x 32 cm)

"Cylinder": (Fits larger / wider packs horizontally. This doesn't fit well in our packs.)
Flat Dimensions: 13" wide x 22.5" tall (33 cm x 57 cm)
Full Dimensions: roughly 8" diameter by 15" tall (20.3 cm x 38 cm)

Pack Liner Dry Bag:
This extra large roll top bag works great as a pack liner that fills your entire pack. It will fit all of our backpacks, including the 52L and 60L Blast and Arc Blast sizes. It is also a good fit on a ULA Circuit, a ULA Catalyst and many other similarly sized or smaller packs. Custom sized liners are available below for larger backpacks.

This is also available below with a handle for dual-use as a protective bag for checking your backpack on an airplane.

Chad "Stick" Poindexter has done a nice video Review of a prototype.

Flat Dimensions: 19.5" wide x 37.5" tall (49.5 cm x 96  cm)

Full Dimensions: roughly 6.5" deep x 13" wide x 31" tall (16.5 cm x 33 cm x 79 cm).

Custom Size Pack Liner Dry Bag:
Our liners are flat like an envelope. To measure for a custom sized liner, lay your backpack flat on the floor, completely empty.

Measure the maximum width of the body of the pack from one side to the other.

Measure the maximum height of the pack from the bottom center to the top, with the pack open.

In the attached pictures of an Arc Blast, the dimensions are about 19.5" wide by 38" tall which is our standard size liner above. As long as your pack is smaller than that the standard liner will completely fill the pack.

Enter the dimensions (width x height) in the box below. Or email us the details.

Custom sized liners are non-returnable unless there is a non-trivial defect in the construction. Finished dimensions may be up to 1/2" off spec.
