Fabulous, but difficult to take off!

This has been an excellent purchase, particularly as the temperature has recently dropped. As I feel the cold in my shoulders and arms but am not a fan of standard wetsuits this has been great. However (and it is a big however!) as the zip doesn't go down the full length of the body it is really hard to get off after swimming. I am relying on another swimmer helping me to pull it off my arms, else I'll be wearing it all day! I think a longer zip could be an easy solution here.

Thank you so much for taking the time to write the review. We agree it is tricky to take off, but it seems to get easier over time. The Yulex jacket is another option for people who are finding the swimsuit too tricky to remove. We will pass your feedback onto Zone3.

Great autumn suit for outdoor swimming. The fit was good, bought xl as most of my cycling gear is xl, although a size 12/14 in normal clothes. The core is kept warm throughout, occasional seep at the back of the neck but not a major issue. Swam mainly breast stroke and had no issues with arm movement. Taking it off takes some skill as the zip prevent double arm release but you can manoeuvre one arm out then the rest is easy. Really happy with the Yulex, great for autumn and spring wear. Would recommend.

Great costume- needs a longer zip

I’m very happy with the swimming costume. Keeps me really warm on longer swims. It is SO hard to get off though! The zip needs to be an inch or two longer. It’s a real struggle to get off. In hindsight I would have ordered the yulex jacket, which is way easier to get on and off.

Thank you so much for taking the time to review the costume. We will feed back the your comments about needing a longer zip. Happy Swimming!
