Marine Grade Hook & Loop / Waterproof VELCRO® Brand Fasteners

After serving recreational and professional boaters, sailors, and mariners for over 25 years, we get the question about the existence of Waterproof VELCRO® Brand Fasteners or Marine Grade Hook & Loop quite often. We hope you’ll find these answers helpful for your water-based application questions.

For the record, there is no such thing as “Waterproof marine grade hook & loop material’. No matter what hook & loop material or supplier you use, these materials eventually break down due to constant water exposure, UV exposure, salt, or a combination thereof.  So we might question anyone marketing a product as ‘waterproof marine grade’.

Waterproof VELCRO® Brand Fasteners

Polyester products are currently the best product for exposure to UV and water. But a word of caution, this performance depends upon how the hook & loop ‘closure’ is expected to perform in addition to the amount of environmental exposure.

We always tell our customers to test products in their application and over time, to ensure they will meet the intended function as well as the test of time. In reality, these are not intended to last forever. After testing, several of our customers use our SPEEDWRAP® Fasteners for water-based and outdoor applications. Some of these SPEEDWRAP® Fasteners are made from VELCRO® Brand ONE-WRAP® material.

What makes the VELCRO® Brand hook and loop waterproof?

Water isn’t necessarily the enemy. It’s more the other elements that are involved with water-based applications including UV, stress on the fastener, and the possibility for salt, which will eat away at most any material.

So while almost any product made with the VELCRO® Brand hook and loop can be exposed to water, it doesn’t mean the fastener will perform as you intend. To increase the chances for improved performance, try to use a polyester hook & loop, and then, as we said, test, test, test!

We have over 25 years’ worth of experience working with VELCRO® Brand Fasteners and we have several unique marine customers. Give us a call to see if we can be of help.

SPEEDWRAP® Brand Suspender Straps™


Problem: How to suspend cables during boat manufacturing

A boat manufacturer stated the need to suspend cables out of the way of employees during wire harness installation.

Solution: SWS SPEEDWRAP® Suspender

Using its carabiner end, the SPEEDWRAP® Suspender is able to clip to a wire cable running above the hull. The hook & loop end of the Suspender was used to bundle and suspend other cables thereby keeping them out of the way of workers. The carabiner easily slides along the wire cable and the hook & loop end can be opened and closed hundreds of times. The end result? A safer and faster working environment.


Problem: Bundling the power cord for trolling motors.

A fishing supply retailer contacted us with a problem of how to manage the power cable for trolling motors to make it easier for fishermen to carry the motor from the boat to their automobile.
