I was able to try and review this product; first impressions is this looked similar to other products on the market but how wrong was I.
Firstly here is a background on how the product was developed from their site. “Back in May 2015, a team of five British swimmers plunged into 9°C shark-infested waters in an attempt to complete the treacherous 30-mile stretch from the Farallon Islands to the Bay of San Francisco, with only a swimming costume, pair of goggles and silicon hat to keep them warm. In a relay-style challenge, the swimmers were to spend a total of 30 hours on board the support craft, where their main concern was to remain warm, dry and protected from the harsh elements. Here at swimzi, it was our job to develop a high-quality product that would not only act as an impenetrable shield against the elements, but also enable the athletes to perform with maximum blood flow when it was their turn to take the plunge. By working closely with the Farallon Swimmers, and adapting key features used in sailing and mountaineering gear, swimzi have developed a piece of weatherproof kit like no other. The XK jacket has been carefully designed to protect against wind penetration whilst keeping essential body heat locked in: allowing you to perform at your best… whatever your sport, wherever you are in the world.”
On to the review, firstly the material on the outside is waterproof, therefor keeping you dry which is a no brainer. The inner lining is made from super soft-warm handle Sherpa fleece. Now this is an important feature, unlike its rivals this product is designed to keep you warm after your warm up and retain your body heat so that you are able to start your race still warm. I was able to compare it with others on the market and this did what the others didn’t do. So I put this to the test, I did my normal warm up before one of my aquathlon races and put the XK on straight after my warm up. I had to wait a bit and it kept me warm before the race. I found I was able to hit the swim better than not using the Swimzi.
The product comes with a 2 way zip system which is very useful which allows you to zip up the hood to stop wind chill. What I liked about the Swimzi was that it felt much lighter than its rivals and it was thinner so therefore not as bulky and easy to carry round.
Another feature is that you can easily get changed inside it, you might think that its too loose but the cords allow you to tighten the jacket.
My conclusion is that this is a great product and in my opinion the best on the market. It is designed for swimmers by swimmers purely to keep you warm after your warm up, unlike others. Its light and gives you the ease of movement. So I highly recommend this product. The photo is me using it at the National Championships and is now an essential part of my kit.
