MIER Waterproof Duffel Bag

MIER waterproof duffel bag features high-quality construction without any compromises. Having one of these, you’ll have no reason to look for another bag for your boating, kayaking, or other outdoor adventures. It’s made of high-density ripstop nylon fabric with thick TPU lamination that provides resistance against punctures and abrasions. You’ll be hard pressed to destroy this bag even with years of the roughest use. Plus, fully taped seams and the waterproof zippers will even keep your gear dry when fully submerged. One interior zippered pocket lets, like your phone, keys or wallet. The double padded strap makes this bag incredibly comfortable to tote around, even when it’s packed full. The four D rings attached can be used for outdoor activities, like attaching this bag to your boat or bike for secure travel. Also, you can fold it when not in use. No matter how you use it, it won’t take much space.

Zipper maintenance: To ensure this duffel is 100% waterproof, we use the airtight zipper which may be a little tight when you first use. You can use the MIER lubricant which is provided to make the zipper slide more easily. See the instruction manual for more detailed usage. Note: please dock the waterproof zipper to create a 100 percent airtight seal when you needed.
