This was a gift for my husband who is both a scuba diver and a sailor. He LOVES this coat. I think he has worn it every day since he got it. Make sure to buy the size based on the size chart and not your typical size. I bought a size up from what he normally wears, but the coat fit perfectly based on the measurements in the size chart. Very good quality, comfortable and warm!
I use this coat for surf fishing and for fishing out on a boat. I am 6' 2" and two hundred pounds. I normally wear an XL in jackets of all kinds. After reading all the reviews and doing my homework I ordered a 3XL. There is enough room to wear a heavy sweater underneath it. I'm sure a wet suit would fit under this coat with measurements provided. This coat keeps out the rain and is warm, I love that the sleeves are long. If you want a snug fit order a 2XL but if you want to add something underneath it order a 3XL. You will not be disappointed. Great service and staff to work with.
I normally wear a LG-XL but in Scubapro products I wear a 2XL.
When over a heavy fleece or 5mm wetsuit is fits like a wetsuit. The neoprene has a lot of stretch so its comfortable and the core has a quick dry lining similar to Scubapros wetsuits. The sleeves are 3 maybe 4mm neoprene with 1mm thumb holes.
The jacket is wind proof and water repellent (tested!), and does keep your core warm. I've worn it with a fleece in 41 degree weather and was fine so it can also be a casual jacket. The bottom pockets are large, I can fin a 7 inch tablet in them and they rest along your thighs.
