I'm not a very confident swimmer, but do enjoy going down to the swimming pool, so today I've bought two of my lifejackets with me to float around in. And seeing as I've got them both here I thought I would compare them. I try on my Marinepool lifejacket, strap in on nice and tight, and get in the water with it, float around, talk about its features, comfort, jump in with it on, see how it performs, etc, and then do the same with the Helly Hansen life jacket, once I've tested both, I compare them and pick my favourite.
