Zip™ Duffle


Combining the convenience of a duffle bag with our highest level of protection, the Zip duffle is a premium, submersible all-purpose gear hauler. It uses the same YKK® zippers used on the finest dry suits, delivering waterproof defense for any adventure or trek—from soggy expeditions to motorcycle touring to rooftop luggage racks.
  • Submersible protection: Rated to withstand full submersion in 1 meter of water for 30 minutes.
  • Easy Access: Diagonal opening with easy-gliding, submersible YKK zipper makes it easy to pack and access contents.
  • Carry comfortably: Webbing handles stay together with a Velcro® grip; 75 L size also has end haul handles.

Documents and Instructions

Yes. Our Zip Duffle is made with a YKK zipper with injection-molded teeth, which is the same kind used in dry suits. It is indeed submersible (meets IP-67: 1 meter submersion for 30 minutes), and the zipper is protected from abrasion by a vinyl over-flap. This helps make the Zip Duffle our most protective product.

We recommend a minimum of 3 folds (aka “rolls”) to properly seal a roll-top dry pack or duffle. For an optimal seal:

  1. Make sure the stiff sealing strips are wrinkle-free. Close the pack/duffle so that the sealing strips are pressed together
  2. While holding strips together, push down to “burp” out trapped air. Once trapped air has been “burped” out, tightly fold the top over several times so that the roll-top closure has been folded at least 3 times
  3. Connect the buckle in the direction opposite to the direction the material was folded, or along the sides when side buckles are present (e.g., WideMouth™ duffle; some dry packs)

All of the dimensions we list for our roll-top dry packs and duffles are the dimensions of the product when it has been properly sealed (tops rolled down three times and secured).

Our dry packs, dry daypacks, and duffles are sized volumetrically in liters. To help illustrate how those volumes translate to real world use, here are some general ideas of what fits in various sizes of our packs and duffles:

  • 20L = a common day size; fits most items one would carry on a day trip
  • 30-40L = a small weekend size; fits most things you’d carry for an overnight trip
  • 70L = a long weekend size; fits a couple days’ worth of gear and food
  • 115L+ = this is the largest size we make; think of this as the “everything and the kitchen sink” size—it holds a lot of stuff

Here's an infographic to help you choose the right gear.

Our Pro Dry Pack has a height-adjustable suspension system that allows you to fine-tune adjustment to fit your torso length. Small = 17in, Medium = 19in, Large = 21in


To adjust the torso length of the Pro Dry Pack:

  1. Lay the (empty) pack on the ground with the shoulder straps up. Loosen the load lifter straps atop the shoulder straps to allow for easy access to the back panel.
  2. Lift upper back panel and shoulder harness to expose the red tab. Unthread the red tab from the plastic loop at the base of the yellow cord.
  3. Unthread the yellow cord and plastic loop through the orange strip (angle the tip for easier clearance).
  4. Slide the long black tongue from its current size setting (S, M, L) and select the proper size.
  5. Do the inverse of steps 1-4 and make sure to re-tighten your load lifter straps atop the shoulder straps.

All of our Boundary and Black Canyon dry packs have removable shoulder straps. If you would like to remove the shoulder straps for transport (e.g., securing pack to the roof of a vehicle or in the bed of a truck, or to streamline the pack for airline travel), follow these steps:

  1. Lay the pack down with the back panel facing up. Unthread the webbing from the load lifter straps atop the shoulder straps.
  2. Unthread the red tab from the plastic loop at the base of the yellow cord.
  3. Pass yellow cord and plastic loop through orange strip (angling tip for more clearance).
  4. Unthread long black tongue until the harness is completely detached. Your shoulder straps are now totally removed.
  5. To re-attach your shoulder straps, simple reverse this process.

In simplest terms, folding the top corners of the pack inward before closing it will help improve your visibility when looking over your shoulder. There’s one technique in particular that we’re fond of—we call it the “Burrito roll”:


  1. Grab the top corners of the pack and fold them inward a couple inches (like the sides of a tortilla for a burrito)
  2. The stiff plastic strip has strategically-placed notches to make this easier, helping create a hinge
  3. Roll the top down and secure it with the easy QuickClip™ per usual
  4. This will cause the top of the pack to have a more narrow profile, improving your over-shoulder visibility

SealLine products use three ratings to describe water resistance:

  • Splashproof: Withstands light rain and splashes. Only some of our products fall into this category. Suitable for use where light water resistance is sufficient, such as summer backpacking.
  • Waterproof: Withstands quick submersions and will float if dropped in the water. Most of our bags fall into this category and are suitable for canoe, kayak and rafting use where boats may tip, flip or be swamped.
  • Submersible: Withstands 1 meter of submersion for 30 minutes (IP-67 standard). Suitable for use in extreme and prolonged wet situations.

With such ratings, water resistance depends on the user carefully and properly sealing the closure. For roll-top closures, this means a minimum of three tight, wrinkle-free rolls. For zipper closures, the zipper must be completely and properly closed.

Polyurethane-coated (aka, PVC-free) dry packs and dry daypacks offer greater puncture and abrasion resistance than vinyl-coated packs, while also being lightweight. Also, PVC-free polyurethane coatings are less harmful to the environment than vinyl coatings.


Vinyl-coated dry packs and duffles are more economical and are resistant to punctures, tears, and mildew. They remain pliable at low temperatures and resist cracking.

Our exclusive DrySeal roll-top closure is easily identified by its two separate stiffening strips below the opening of a roll-top product. This makes it easier and more intuitive to achieve an optimal seal—for the first “roll” in closing the top, simply fold the top over between the two strips of material, then roll closed at least two more times.

This design also amplifies protection from the elements by adding an additional “virtual” roll.

Welded seams use radio frequencies (RF) to join two pieces of coated fabric together at the molecular level, effectively bonding them together as one. This strong, reliably waterproof construction method is far superior to sewn-and-taped seams.

With sewn-and-taped seams, two pieces of coated fabric are held together with thread and a piece of protective tape is placed over the threads and seam to provide water protection. A RF welded seam can withstand up to 2x more stress than a sewn-and-taped seam, resulting in a more protective and longer-lasting seam. This is why we use welded seams with all of our dry bags.

Regularly cleaning and maintaining your dry pack, dry daypack, or duffle will substantially increase its life.


After each use, clean and air-dry your dry pack, dry daypack, or duffle. Dirty packs or duffles should be washed with a soapy sponge and rinsed, allowing them to air dry. Store clean packs or duffles completely dry, inside out. Avoid any direct contact with insect repellents or solvents—if contact occurs, wash the pack or duffle thoroughly with a soapy sponge.


For vinyl-coated dry packs or duffles, such as our Boundary™ Dry Packs, Zip™ Duffle, or WideMouth™ Duffle, an occasional wipe down with a vinyl preservative, such as Armor All®, will help maintain the vinyl-coated pack or duffle’s suppleness. (Armor All® is an Armor All Products registered trademark.) Do not use a vinyl preservative for polyurethane-coated (aka, PVC-free) dry packs, dry daypacks, or duffles.
