Wet weather bag
« on: July 23, 2018, 05:40:40 PM »
First post in a long time...

I'm helping a coworker with a project idea that he came up with. He wants to design an improved wet weather bag, that will be an improvement from the US Army wet weather bag.

A lot of the improvements focus on design instead of material. I made him a prototype out of 500D cordura, and its water resistant. but not waterproof. 

What would be a good material for the final prototype? Does anyone know what the current wet weather bags are made of? I have one, just don't know the name of the fabric.  I'd also be interested in knowing if there are any suppliers of fabric similar to the one that SeaLine uses for their bags.

Or if anyone has any suggestions in general, like possibly a way to spray a sealant on cordura to make it waterproof...

Any help, or criticism, is appreciated.

10oz or 18oz truck tarp vinyl, tape the seams before sewing(commercially made/mass produced products are probably hot-air welded seams or ultrasonically welded seams) and Aquagaurd zips.

At least this seems to be how most rafting/watersports bags are constructed that I have seen.

There are also heat sealable fabrics. Nylon/Ripstops

I have sourced 10oz from Top Value Fabrics, but they also carry heavier weights. 18oz is one of their mainstays:
