Occasionally you run across a hidden gem. On very rare occasions, it cost less than $20. After fighting to get comfortable with a pant belt under a pack belt, I ran across this gem. Zero slip, infinitely adjustable, no buckles or metal hardware, and you never know its under your pack belt. Everybody who straps on a pack needs this belt.
They have a 3-4 week lead time. Mine was delivered in a little less than 3 weeks.
