SealLine products use three ratings to describe water resistance:



What is the difference between polyurethane- and vinyl-coated dry packs and duffles?

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.

What is special about the DrySeal™ roll-top closure?



How do I properly seal my roll-top dry pack, dry daypack, or duffle?

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
  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)
Are the listed dimensions for roll-top dry packs and duffles measured rolled or unrolled?
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).
Is the zipper on the Zip™ Duffle really waterproof?
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.
Which size of dry pack, dry daypack, or duffle should I pick?

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.

How do I adjust the suspension on my Pro™ Dry Pack to fit my torso length?

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.
How do I remove the shoulder straps on my Boundary™ or Black Canyon™ dry pack?

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.
  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.
Is there a way to improve over-shoulder visibility with the Urban™ Dry Daypack?

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

How should I clean, maintain, and store my dry pack or duffle?

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.
