I have two Cabelas 4x (65") ones in the vinyl, and two 5x (77") in the nylon. Both work great, but it takes a few minutes for the vinyl ones to open when they're cold. They get a little stiff in cold weather. I bought the vinyl ones on sale a few years back for 12.50 each. Bought all they had left in the 3 and 4x. Got the nylon ones the same way, but paid around 35 for those.
