Review: Good suit. - I wear it from 65Deg down to mid 50's without any additional layering. Very comfortable and stretchy.
Review: Great fit, great performance, one minor annoyance - XXL was perfect for 230lbs/6ft tall with a big belly/chest. I've never had a 4/3, but have decades of experience using thiner wetsuits and neoprene gear for different activities. Most of my stuff is around 2mm. It's crazy how warm 4mm is - I used this suit in 50-55F water and I couldn't even tell I was in the water. Only flaw with the product is the neck velcro easily gets stuck inside the suit and is very difficult to get un-stuck once the suit is on. I know what you're thinking: "they all do that." Not like this; the velcro absolutely welds itself deep inside your shoulder, even if you try to be careful about not dragging the flap in. This annoyance is worth it for the price; still a great value. No fault of the product, but the suit was sent in a box that was literally 6ft long, 3 inches deep, and around 30 inches across. This is obviously absurd, and might be a consideration depending on where you are sending the suit. Also, the suit had clearly been tried on and returned, which is a little gross, but fine with me.

### ⭐⭐⭐⭐⭐ Warm suit. Doesn't let cold water flush through the zipper !
*by A***R on April 7, 2024*

I'm 5'11" 205lbs kinda stocky. I've sometimes have to wear a XXL because of my shoulders & chest but then those suits are loose in the legs on me. This fit me perfect ! I was concerned that it doesn't have a bat wing under the zipper & usually this means cold water runs down my back " But that's not the case with this suit" zipper holds out the water really good! It's got fleece inside which keeps you warm in cold water. Great suit for the $ also they packaged it nice & it didn't come all wrinkled. I've had new suits come wrinkled from other suppliers as they put the suit in a huge box & it just flopped around during shipping.
