I do not know how Kramer's are now, but I bought a few when they first came out about 15 years ago.
Very disappointing.
Very wimpy, and you had to sew it up yourself to "tighten it up" for more of a custom fit, or any fit at all.
So I never used it at all.
Hopefully they are better now.
Those 5.11's look like they are done right.
and BTW, I am a big Kramer fan, have some stuff over 20 yrs old still going strong.
