I bought one yard of dyneema as an emergency groundsheet for me to lie on or to put my dyneema (DCF - cuban fiber) backpack on. I am happy it is as goods as all my other dyneema products - tent, backpack, groundsheet, etc.
It is very light and good fabric.
Great material to work with, easy to make dry bags out of
Basically my project was based on dry bags for bike packing. Wanted something durable yet light. Light and durable is what this is. Still haven't had a chance to try them since the snow continues to fly. Still recommended just by ease of use and feel so far.
Mid weigh fabric, but really strong.
