Wow, I've never had that happen. I used the primos slings for a while, but they stretched out and I'd have to replace them. I'd have to check the brand of the one I'm using now. Its pretty tight on there and I haven't had any issues. I love throwing my bow over my shoulder for the walk in and out.Last year it the bow fell out from 20ft and this year opening day morning it fell again. It has been cinched done all times and walking with it it stays put. When you have over $1500 wrapped into your bow any fall is bad. Luckily opening day I was able to hammer the dovetail straight on my sight. My sling is a Cabela's brand one which i got as a gift. It works for walking not so much for climbing.
