O'NEILLMen's O'Riginal 2/1mm Back Zip Jacket

I'm about 5-10 185lbs and the XL was just about perfect. A little tight on the beer belly but the back zip makes it super easy to get on. Super comfy for surfing.

I usually wear a XL t-shirt but can fit a large easy. The only complaint I have is it could have been longer. Use it about 20 times snorkeling so far.

Great for the cooler waters in between summer and fall. The chest has full rubber with same grip on board as my full suit.I’m 6’ 200-205 and the arm length is great, length is standard and hits right at my hip bones. If they would have had a Tall version of this with an internet Cara 1” I would have bought it for the body length. The arm length is perfect as I have longe arms and torso and don’t like the sleeves inching up as I paddle so it will be fine. Will be worn when I dive also when deep and rash guard wouldn’t be sufficient.

I got this extra extra extra large size one just to see if I could have a little looser, easier to put on and take off neoprene top for the summer. Turns out this fits pretty darn good it's not tight but not flappy and loose and I thought the arms would be long but it's pretty good. I fully expected to return it but it's kind of just what I was looking for, a looser more casual neoprene surf top. For good measure I suppose I would describe myself as 5'10 and a overweight but not crazy much, with XL t-shirts.

comfortable out of the water, warm in the water.

I used this to surf and wing foil for over 2 years here in honolulu, using it couple times a week. It takes a beating and keeps you warm enough. I like the zipper in the back and doesnt both you when on the board paddling. I'm 6' 165LB and large was a tight but good fit when i bought it, its looser now as expected after that much use. Nothing tore, the zipper is still fine, the only thing is the back panel above the zipper is getting some holes since that panel is thinner material. I think its caused by how I remove it where i tend to yank that area to get it off the top of my head. Otherwise its great wetsuit, I'll keep using until the back panel complete falls apart in maybe another year ?

Zip up back is convenient. After a full season it’s holding up nicely.

Received damaged. It was ripped in the shoulder area.
