Hiking Waterproof Backpack | SEVENTY2 Shell
Comfortable to carry. Rugged as the roughest terrain. Our waterproof backpack shell combines military-grade toughness with a lightweight feel that’s perfect for hiking and traveling. This is the same backpack that’s used in our Seventy2 Survival System, but without the insert and supplies. Use it to build your own survival kit, or enjoy having a waterproof daypack for everyday use.
We built the waterproof backpack to be strong and long-lasting:
- Sturdy, one-piece construction
- Woven from 600D tarpaulin
The backpack is entirely waterproof, due to its:
- 100% polyurethane shell
- Waterproof zipper
- Sealed seams
It’s so airtight, you can even use it as a flotation device.
We didn’t sacrifice comfort for strength. Wear the waterproof backpack shell from our Seventy 2 Survival System for miles on end in total comfort. Both the shoulder straps and hip straps are padded and adjustable.
We incorporated ventilation in the shoulder straps and in the back to improve your airflow and keep you comfortable while you’re traveling.
This is the perfect waterproof hiking backpack. There are hands-free flashlight mounts so you can freely use your arms for gripping and balance. The backpack also features reflective materials to keep you visible in any location, day or night.
Additionally, we designed the waterproof backpack shell with:
- 48 L storage capacity
- 3 pockets
- 6 side loops for attaching additional gear
Protect your gear with the waterproof shell from our Seventy 2 Survival System, and make your journey safe and smooth.
Which fabric is the most durable?
Polyester is considered the most durable fabric. We use 100% polyester to construct our Seventy2 shell.
What does the “D” stand for?
Our shell is made from 600D tarpaulin. The “D” stands for Denier, which is a unit that measures the thickness of a fabric. Our 600D backpack has a high degree of thickness. It’s extremely durable.
Which fabric is the most waterproof?
There’s no natural or synthetic fabric that’s waterproof all on its own. To be made waterproof, a fabric must be coated by an underlying layer of waterproof material. Our tarpaulin shell is coated with 100% polyurethane waterproofing. It’s so effective that you can use the backpack as a floating device.
What is TPU coating?
TPU stands for “thermoplastic polyurethane.” It’s our waterproof coating. TPU is dense enough to repel water, but it’s also soft and flexible.
What is a DWR coating?
DWR stands for “durable water repellent.” DWR is coated on fabrics to keep them from soaking up water, which helps them remain breathable.
What’s the difference between waterproof and water resistant?
“Water resistant” means that a material can withstand some degree of water, but it can’t handle exposure to a large volume of water for a long amount of time. “Waterproof” means that a material is entirely impenetrable by water. It can withstand a large volume of water over a long span of time. Our Seventy2 backpack is waterproof. Carry it through heavy rainfall or submerge it in a lake—it’ll be just fine.
Does waterproofing degrade over time?
All DWR coatings degrade over time. However, this happens over many years, and it doesn’t affect the backpack’s waterproofing—only the breathability.
How do you take care of a waterproof bag?
The Seventy2 backpack can handle any adventure you take it on. But you can always improve its lifespan by preventing dirt and mold from accumulating. Care for your waterproof bag by:
- Storing your bag in a dry place that’s removed from direct sunlight
- Storing your bag away from solvents (sunscreen, gasoline, alcohol)
- Washing your bag after every use
