I've hated nearly every strap I've bought/used, but these go on every guitar/bass as soon as I get it home.
I've put Clip-lock straps on my instruments for decades, and these cotton ones are Nirvana. They don't pull on your neck, they don't slip (even with neck-heavy instruments) and no matter how much you thrash around, your guitar will never fall off.
I've seen some people complain about the buckles damaging the finish, but it hasn't put so much as a scratch in my Jackson, and it's been on that guitar since 1994. I trust them so much, I've put one on my Music Man Majesty 7 with the gorgeous Kinetic Blue paint. That's confidence.
I like these so much, I have a spare ready for the next guitar I purchase.
