Wellllll. . . . I tried a Tough 1 blanket about 8 years ago and it quite literally unraveled. . . the stitching
just fell out - it was bizarre. I don’t know if they’ve improved their quality since then but I haven’t had any desire to find out.
I have a sheet and medium weight going into their fourth season with no issues, and this is the first year I’lll re-waterporoof them.
I have one going on year two with no problems
