SWIMWEAR GUIDE

Zone3 offers purpose-built swimwear for every kind of swimmer. Whetheryou'relogging laps in the pool, refining your technique ahead of your next triathlon, racing competitively, or swimming through colder months, our swimwear range is designed to support how you train.

PERFORMANCE SWIMWEAR


Our swimwear collection is built to a single technical standard across every cut and every size. 

Classic suits, strap back designs, high-neck styles, long-sleeve options and jammers are all constructed using the same Xfinity Renew performance fabric, engineered for durability, shape retention and long-term chlorine resistance. 

Available in sizes 6–22 across women’s styles. 

There is no variation in quality between cuts. No difference in construction standard. 

The choice comes down to coverage, feel and how you prefer to move in the water. 

Best for:
Pool training, open water sessions, and everyday swim performance

FINA APPROVED SWIMWEAR


Zone3’s FINA-approved swimwear is engineered for speed and built to meet the demands of competitive racing. 

Our jammers and kneeskins are constructed from ultra-light, hydrodynamic PaperLite fabric and shaped for a precision, second-skin fit to reduce drag and maximise efficiency. 

Designed for race-day performance without the premium price tag, this is competition kit built for swimmers chasing speed. 

Best for: Competitive swim racing

BUOYANCY SHORTS


Buoyancy shorts are a focused 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, allowing you to focus on technique and stroke development. 

Ideal for pool-based training blocks or warm-water open sessions, they deliver targeted support without relying on full wetsuit buoyancy.  

Best for: Technique sessions and warm water swims

Swimwear for Added Warmth 


Planning to keep swimming during colder months?

Yulex® Natural Rubber

The Zone3 Yulex range uses plant-based rubber to provide natural insulation and flexibility, offering an alternative to traditional neoprene without compromising performance.

Ti+ Thermal Collection

The Ti+ collection integrates a titanium lining that reflects body heat back toward the core, delivering warmth, comfort and confidence during cold-water sessions. 

Ideal for swimmers training outdoors in cooler conditions, or worn as a base layer under a 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.

Suit is perfect for swimming, paddle boarding etc. The fit is comfortable and flexible so you have full range to swim crawl or breaststroke. Sleeves add colour but also great for protection in the sun. Inner bra shelf adds a bit of support for flattering fit. Also small inside modesty hook/catch to hold suit together at the front in case zip comes down! True to size, not high cut, good length in body for taller ladies.
