ZONE3 Women's OWS Ti+ Thermal High Neck Costume

Titanium-infused lining panels front and back reflect your body heat back to the core. That makes the Ti+ High Neck Swimsuit a thermal swimsuit for open-water swimmers who keep going as the water cools, and a warm layer for cold pools and lidos. The high neck cuts the cold air and wind you meet at the surface. Wear it on its own while the water is still swimmable, then as a base layer under a wetsuit when it drops further.

WHO IT'S FOR 

You swim outdoors and you do not want to stop when the temperature does. A standard costume gives you nothing once the water turns, and a wetsuit in early autumn is more suit than the conditions ask for. Ti+ fills that gap. 

• Open-water swimming through the cooler months 
• Cold pools, lidos and unheated outdoor water 
• Early swims where the air is colder than the water 
• Layering under a wetsuit once the water drops further 

WHERE IT SITS IN THE RANGE 

Ti+ is the thermal end of the Zone3 swimwear range, and this is the sleeveless cut. The Ti+ Long Sleeve Thermal Swimsuit carries the same lining panels and adds arm coverage for colder air and windier water, and for heated pool training the Zone3 performance swimsuits in Xfinity Renew are the better buy. 

KEY BENEFITS 

1. Your body heat stays where it is useful. Titanium-infused lining panels sit front and back and reflect heat back towards the core rather than letting it pass out through the fabric. 

2. The cold air at the surface stops being the problem. The high neck covers the chest and throat, the two places wind and cold air reach first when you lift your head to breathe. 

3. One suit covers the whole of the cooler season. Ti+ works on its own while the water is still swimmable, and as a base layer under a wetsuit once it drops further. 

4. The suit holds its shape and colour through the season. The premium Italian outer is 100% chlorine resistant and sunscreen resistant, rated UPF50+ for long outdoor swims, and it dries quickly between sessions. 

5. Nothing rubs on a long swim. Concealed seams keep the inside and outside smooth, the bust area is double lined, and the centre-rear zip sits flat against the back. 

WHAT YOU'LL FEEL 

The first thing you notice is how little there is of it. The suit sits close and light, with none of the bulk of a thermal layer that works by thickness. Once you are in, the cold shock at the start passes faster than it does in a standard costume. Your shoulders and arms move exactly as they always have. Stop to tread water and you feel the difference across your chest and throat.
