Jay J2 Back AirExchange Covers

I think this is the best ext cath to use for active people like me. Getting in/out of car and doing weight shifts often can cause the ext cath with shorter sheath to slip right after after just 3,4 times, especially when you wear jeans. This one stays on for even up to 48 hours if you want to. That's why I feel totally safe when wearing one of these on the planes and in transit to go to Vietnam which can take up to 18 hours. I have tried quite a few other styles but have never felt as confident, safe and relax as while I'm wearing this model. I'll have to remind myself this. That's why I felt like I should write this review.
