Here’s an interesting question that came in over our blog today:

Q: I’d like to make a vest out of the SOL Thermal Bivvy-  should the seams be sewn or will an iron work to weld seams?

A: My advice is to sew the seams, rather than trying to weld them.  If using an iron to weld seams, I would be worried about excessive heat weakening the fabric or causing the two layers of the fabric to separate.
