LemorecnMens Wetsuit Top Premium Neoprene 3mm Zipper Wetsuit Vest

I'm submitting this to help with sizing, I won't get a chance to use it for snorkeling for a few more weeks. I have worn another maker's version in the past in cold(ish) water to snorkle. This feels fine, decent zipper. See photo for how it fits in my case, I think I got the correct size as it should fit snug. I have to pull it about 2" to zip it shut, but it is easy to do. I am 70" (5ft 10), 166 lbs, about 39 inches at widest point of chest and about 36 widest at belly (cut me some slack, I'll be 70 soon). Using their size chart I ordered the Medium, and it seems correct. And yes my head is transparent.

Why did you pick this product vs others?:For the price, you can’t go wrong with this vest!

I'm 6'4" and 240 lbs. I'm not fat, but because I'm 83 years old I do have an old man's shape. In clothing, I usually buy 2XLT shirts and size 38 pants.I bought this vest in XXXL and it's wearable but a little too snug in the chest. I previously bought the neoprene pants in XXXL and they're also snug. The moral to the story: buy a larger size than you would think you need.

Great vest! Perfect for diving in the carribean waters. I wear size large shirts and purchased this item in xl. Perfect fit

These run a bit on the small side - I am a bit fluffy and way too big even though I am at the top of the chart - my advise - order once size larger

I ordered 1 size up and have a good fit. For wetsuits, I normally order 2-3 sizes up because of wide chest (51") and large arms. Dive in 82 degree water and this is perfect.

I’m 5’11 185 and it fits perfect, just snug enough like a wetsuit should fit. I swim laps in a 75’ pool and it’s the getting in and out of the pool on cold days that I enjoy the extra warmth. Good zipper, good fit, so far so good.

Works perfectly
