Our open water recycled swimwear collections are designed for swimmers who value performance and purpose.

It also boasts 100% chlorine protection, UPF50+ protection, and sunscreen resistance. 

Best for: Open water swimming with or without a wetsuit

Fina Approved Swimwear  


Zone3’s FINA-approved swimwear is engineered for speed and built to meet the demands of competitive racing. The jammers and kneeskins are designed with a precision fit and constructed from our ultra-light, hydrodynamic PaperLite fabric. Each suit delivers a streamlined, second-skin feel to reduce drag and maximise efficiency. Focused on performance without the premium price tag, it’s race-day kit that makes elite-level speed more accessible. 

Best for: Competitive swim racing  


Buoyancy Shorts  Buoyancy Shorts 

Buoyancy Shorts 


Buoyancy shorts are a go-to training tool for swimmers and triathletes looking to refine body position and build efficiency in the water. Designed to simulate the lift of a wetsuit, they help improve hip alignment and reduce drag, similar to that of a pool buoy allowing you to focus on technique and stroke development. Ideal for pool-based training blocks, or in the open water when the temperature is warm, they offer a performance edge without relying on full wetsuit buoyancy. 

Best for: Technique sessions and warm water swims 


Swimwear for Added Warmth  Swimwear for Added Warmth 

Swimwear for Added Warmth 


Planning to keep swimming during the colder seasons? For added thermal protection against the elements the Zone3 Yulex range uses plant-based rubber for natural insulation and flexibility, offering an natural alternative to neoprene without sacrificing performance. The Ti+ collection features a titanium lining that reflects body heat back towards the core, delivering warmth, comfort, and confidence in open water and winter swim sessions. Ideal for those braving it in skins in cooler temperatures or to wear as base layers under your wetsuit. 

Best for: Cold water swims

I ordered this as I usually swim skins all year round. The delivery was quick and I was in open water within a couple of hours of it landing on my doorstep. The fit is lovely and it is cut well across the back. I just swam for 80 minutes in our local reservoir (probably 15/16 degrees) and I think it really helped to keep my core warmer. I think it's a good option for swimmers who don't want to use a wetsuit but maybe need to do some longer swims. It's a well designed item.

Fabulous design! Flattering and comfortable, good fit. Love the high neck which makes it more snug for open water swimming. Long zip which makes it easy to get in and out off even with cold fingers! I have been wearing this under the Yulex swimsuit and it's a perfect combination with the black underneath the blue. Got a size 10 as per size chart and its a good fit

Exactly what I was looking for - I find wetsuits very restrictive and make me too buoyant - but needed a little more warmth to extend my outdoor swimming season. This definitely kept me warmer - but very comfortable and no impact at all on my swimming. It was stretchy and seemed pretty robust - easy to get on and off. I spent ages looking at different options and am very glad I went for this even though it cost more than some of the alternatives.

Comfortable, and good for tall/long frames. Nice cut at the legs - flattering but not high cut which I find uncomfortable. I wear this for open water swimming all year and always like to have an extra one in stock as this is my favourite swimsuit. They last for years. Great item!
