In the thinner 25mm plain rectangular style and I'm only interested in a 3/4 length. The thicker one i bought here last year has developed one of those anoying leaks and will not stay compressed.
Happy to negotiate a price on one in excellent to very good condition.
Lighter weight is better but older are OK
I might be willing to look at other brands but past experience with Katmandu and Macpac hasn't been good
