Thinking of picking one up to help with the 2 to 3 days of lower back pain after a day on the water. Looking at the website it says you should add an inch to your waist size if you wear a wetsuit. It also gives you 2 different fabric options based on the same. What have people done that spend pretty much equal time on the water with and without neoprene (up to 5mm)?
Coleman made my back mould against my skin and the harness fits fine with or without a wetsuit. I wear a 5/3 no worries... Perfect.
