O'Brien Mens Traditional Neoprene Life Jacket

I ordered a large, which states it fits chest sizes 40-42, although some sites have this exact make/model stating it fits 40 to 44 inch chest sizes. I have a 40 inch chest, I'm 6'3", and approximately 180 lbs. The large fits perfectly, and looks trim and not bulky. It is exactly what I wanted and I'm amazed I didn't have to order a size up, as many of the reviews state. Based on this purchase, the sizing is exactly what the company stated.My personal view: I watched some videos on life jacket sizing, and you need to be able to fasten all zippers and buckles while feeling snug, but not too tight. Life jackets should hug the body snug with a little grip, because otherwise the water will lift if off the body if it's too loose, making it flop all over the place. You're supposed to sit on the floor, legs extended outward, and let someone grab the shoulder sleeves with their hands and lift upward as if pulling it off over your head. If the shoulder sleeves rise upward over the ears, it's (supposedly) too big. It will lift up over the head when completely submerged in water, so you need a different size, or at least to make it much tighter (or try a different brand/make/model if you can't find the right fit.I bought two of these life jackets, both large, and they both fit identically and perfectly. I returned the color I didn't really want because the one I wanted came back in stock just after ordering my second choice. Sizing was consistent for both, fitting like a glove with a great style and comfort.Based on the other reviews (and I read them all over the course of three weeks before pulling the trigger on this purchase), I get the impression that a large portion of the population thinks it's smaller in body size than it actually is. I don't think most people actually know their true chest size or their waste size, unless they've been to a tailor in recent history; and clothing companies have adjusted sizes each year to accommodate the "body positivity" agenda on humanity. Clothes marked "large" five years ago are now labeled "medium." If you put on a couple of pounds, it's going to that area for most men (man boobs and upper arm fat) in tandem with love handles. Both spots are hugely affected when it comes to finding a proper life jacket.Anyway, for those medium-tall or taller guys who are also lean with healthy bodies and low BMI (meaning healthy, not just "skinny" or skin and bones), a large size should fit very well for someone in the height range of 5'10" tp 6'3" and in the weight range of 170 to 190 lbs, with a chest size range of 40 to 42 inches, and a waste between 32 and 34 inches. I think a 44 inch chest size would be bordering on too snug, there's a little wiggle room once you break-it-in and the neoprene relaxes after a few water adventures.I freaking love this life jacket.

The extra large is snug on me. I am 6' and weigh 215 lbs. Likewise, the large was snug on my pretty wife, whose dimensions I could not say even if I knew them. I suggest you order one size larger than you think you are. They are comfortable but they have no stretch panels. I assume they float.

Fits , nice quality

My chest is 42", but on reading other reviews chose an XL (44-48) and it fits snugly. The construction seems good, per expectation with O'Brien. NOTE this has a 70 rating (of 4, i.e., 50-70-100-150), and favors mobility, so more room around armpits. neck and such. It would not be optimal for long exposures in open ocean waves, as one would have to fight a bit to keep one's head above the wave crests (e.g., 150 would hold one up in the water like a bobber but would be bulky/restrictive if skiing or jet-skiing on a lake.

6’ 2” 210lbs Large fits perfect. It’s comfortable to wear. Had it on a few times this year riding the jet ski so I kept it on the whole time on the water. Wearing it for 3-4 hours and it was comfortable. It doesn’t rub or irritate you under the arms around the neck and at the waist like some other vet. I bought 3 on them now. One for me, my wife (L for the up top fit), and daughter (small she’s 11)

Worked as it should, love the colors and the fact it zips and only 2 clips

I’m an XL and it fits snug if you’re a little bit bigger XL you might want to go ahead and go to a 2X I bought L and an XL They’re both very nice

I'm 5' 9" tall and weigh 195-200 lbs and the XL size fits me great. I wear a size 44 jacket and that put me directly between a size L and XL on the product's size chart. Considering all the reviews said this jacket was 'way too small' I ordered the XL which was the larger size, but other reviews had me worried that I should have even gotten a XXL.The life jacket is nice quality and has a zipper. The material is somewhat stretchy, so it is probably normal that you may have to suck it in a bit to zip up the zipper. However, the life jacket is stretchy and comfortable and you need it to be snug so it doesn't ride up over your head in the water. I used the life jacket on a wave runner for 6 hours and it was comfortable and I never felt like it was too tight. The design of the arm holes allowed for good range of motion.I recommend getting the larger size if you are in between or in questioning it at all, but you do not need to order up 2 sizes. You may have to suck it in a bit to zip the zipper, but the material is stretchy and it fit comfortably.

My wife and I ordered 3, extra large. we measured 3 times before ordering . We can barely zip them up. I was not pleased. Recommend 1 size up.

This is a one xl at best. I have other 1XL life jackets that are larger.

It's a quality life jacket for sure BUT you better order a size larger than you are or you'll be disappointed!
