Let me preface this with... I love this thing... So we probably all run around with a wally world vest, or local sporting good store offering for a while thinking it's fine. I just pretty quickly grew tired of getting hit in the neck with blocks of foam. I had a sport PFD for a bit, which was neoprene and fit snug and didn't move at all and was nice but, I was getting into kayak fishing and thought I would be able to use a few pockets on me. I didn't want to load up on a bunch of crap like I see some people... I mean jeez guys, it is supposed to float in case you go over not strap 2 days of gear onto while holding your beer. I tried a few on, all the big names. I did also like the big orange OS vest from that 3 letter word company. But honestly this one felt reaaaaally good. The way the thing cinched down just kept it from moving at all on me. Plus I'm a pretty beefy. 5'10 225. 46" chest. 36" waist. I got the L/XL and it fits just fine even with a breakfast burrito in the gut. I have room for a couple of shirts or thin 3mm (what I had to test) wetsuit underneath. The pockets hold my Pixel 4XL, albeit barely, with it's chunky case on. A pair of pliers, tackle scissors, bunch of little bits and bobs in the mesh internal pockets, a rape whistle, a plano 2 sided mini-box, tigers milk... These pockets are hardened, so it protects the stuff inside and makes sliding over them easier. Outside just a light and one of my moras. Lots of room for more, but I am not big on looking like a Christmas Tree. Plus it gets harder to get back in the yak with all the stuff dangling. 500D Cordura baby! The only PFD I could find that wasn't disposable. Seriously how many people I ran into that had 1 or 2 year old vest with holes in them... man get out of here with that nonsense. You think I'm gonna drop a bill and a half for trendy fashion gear on the water? Move along... I want safety gear that is purpose built and is going to last. Comfort, okay I already said I love it and that it doesn't ride up. But geez you really don't know it is on. You can paddle all day and not even feel it anywhere on your body. Forward, Reverse, or Draw, it all feels smooth the vest doesn't move or encumber you in any way. I only had to adjust a couple of times, and this was because I was crawling around to reach my ice chest lol and even then, just barely more of a twist than anything. Supposedly the foam in this will mold to my body over time, I can't imagine this becoming more comfortable over time, I am already feeling spoiled by it. Negative, probably the only thing I can say, I don't like adjusting straps all the time so I leave them pretty well adjusted to where I had them last. This makes it a bit more difficult to "zip" on than others that have the belly buckle before you zip. So I have to squeeze my arms together while trying to zip up to sort of pinch the sides of the vest together to get some slack. Now obviously this could be avoided if I wasn't a lazy SOB. But I mention it because I am pretty sure 90% of the world will do the same thing. The flip side is, this is more comfy than having a belly buckle pinching into you all day... So if you are on the fence, looking at all the PFD's out there and don't know which ones to get, are worried about function and comfort over which ones your friends will like more. GET THIS ONE and be done wasting time. CB
