The New Openwater Core is specifically designed for swimming and training in open water as safely as possible. It provides maximum visibility thanks to its orange panels. It also provides the thermal insulation needed to maintain an ideal body temperature. The use of 2 to 2.5 mm thick Yamamoto neoprene provides great freedom of movement for longer, more comfortable swimming. HIGH VISIBILITY To keep you as safe as possible in the water, this wetsuit has been designed with a high-visibility orange that will make you visible to boats and other swimmers, so you can be located at any time. FLEXIBILITY For more flexibility in all phases of the swim stroke, Yamamoto 39 neoprene is used together with 2 mm Infinityskin high-end lining. This material has high elasticity that allows it to be used in different areas of mid-range wetsuits. This material requires between 45% and 35% less force to stretch than conventional neoprene. FIT The 2.5 mm Yamamoto 38 material is used in the torso and legs. This technology provides good thermal insulation and a good fit to the swimmer's body, preventing the neoprene from separating from the skin and water flowing into the suit.

I haven't even received the wetsuit after 5 weeks post order. .. would love to be using the product and provide a review! I'm sure the product will be good once I receive it though.

My previous Orca wetsuit ( Orca TRN ) nearly lasted for two years. I had a 2 to 3 inch split below the zip so hence my new wetsuit. The hi-vis wetsuit is very visible to boats when swimming in open water. I have swam in very cold water ( approx 5 degrees centigrade ) for 31 minutes and found the wetsuit very comfortable. I wasn't too cold when I got out of the water.

I like the Orca line, have the shorty as well as this one and the swim cap, great products, well made and really do the jobOnly criticism is the velcro flap at the top of the zipper sticks like you know what to a blanket and to anything it comes in contact with so if you have someone to help zip you up it would be handy

Bought for my son who does various water sports. The staff were very helpful with the correct sizing, fit is spot on. My son is very impressed with the wetsuit in terms of comfort, flexibility, and warmth.
it is my first wetsuit and it has honestly exceeded my expectations. The only problem is that the size chart isn't reliable. The model recommended to my dimensions would never fit me. I had to take 2 sizes bigger.
My first wetsuit so nothing to compare it to. It was recommended by my partner who has a different model and it’s very comfy giving me the confidence to swim 2 and more kms at a time. I’d recommend it based on my limited experience. Cheers.
Bought for winter sea swimming. Warm enough keep me in the water and not too buoyant for front crawl or at all restrictive.Very high Viz.Great value, good quality wetsuit.Fast delivery and simple returns policy (bought 2 pairs gloves returned 1 pair)Will buy from Sigma sports again.*****
Delivery and Packaging spot on .I went for size 7…….I’m 5ft 11 and 78kg with a 31 inside leg and a 40” chest , it fits like a glove , best fitting suit I’ve had ,it also has amazing flexibility around the shoulders . This wetsuit is a winner .
Bought as a second, lightweight neutral buoyancy summer wet suit to compliment my heavier winter wet suit. The quality is fantastic. Only stitched and not welded seams so water ingress is immediate, however, you'll be warm and toastie in no time at all. Super stretchy neoprene around the shoulders means that you barely notice that you are wearing it.
This wetsuit is brilliant for longer sea swims in the summer. Unrestricted arm movement, highly visible and excellent buoyancy. Really good value, very happy
