The more you reuse it the less "clingy" it gets and it stretches out after a while but mine has been used 4 time on 3 rifles in the middle of a cold norther Michigan winter and it's still useful. I'll bet it performs even better in warmer weather. It holds in heavy snowfall but don't know about rain yet.
Got some of these before, and i love them. However, the color on the ones i just ordered are not at all like in the picture or like the ones i already have
