Bought this to replace my really wide leather strap that was sticking into my neck. I play bass slightly lower than in sitting position and the "Short" version is plenty long! Be sure to measure your old strap to choose between long and short versions!
Pros:
+ Doesn't get hot when you sweat on stage;
+ Doesn't stick to your shirt like leather does;
+ Distributes weight nicely (probably due to the memory foam) without being overly wide;
+ I dig the looks;
+ Looks like it can take a beating;
+ Leather free (good if you're a vegan);
Cons:
- Metal rings can damage your guitar's finish;
- Huge MONO logo;
- Ends made of really soft material, which makes them stick outwards when standing;
The metal rings did beat up the finish on my bass, because I put the bass in the gigbag with the strap on, so you might want to take it off. I play a neck-heavy 5-string bass and the strap helps greatly, it even seems to have alleviated my left shoulder pains!
All in all - highly recommended as an alternative to leather straps, and in my opinion - a better alternative!
