Which of these sizes would fit a thermarest trail pro?
PING V They should all be long enough but go with the longer ones and just cut to length. The short one doesn't leave enough length to hold and cinch tight.
They are too expensive for what they are. Just basic cinch straps. Just go to the camping/hiking section at Walmart and get some of the cheaper ones.
KEVIN D they were ok but i changed to velcro as it seems to strap tighter.
hope this helps
