Threo's Eton Dorney Women's Triathlon Suit combines striking graphics with beautiful fit and a real understanding of what us women need in a tri suit. 

The deep grey colourway is one of the most flattering around, but as soon as you overtake anyone they'll get a flash of aqua blue from the back. It's ideally cut with front and side panelling for optimum mobility and comfort, and the wide grippers ensure no digging into your legs. The quick-drying compression fabric minimises unwanted movements to ensure you perform at your best.

The Threo Eton Dorney Tri Suit is designed to inspire confidence in triathlon newcomers and more experienced competitors alike, and you only have to look at the list of specialist details to realise why it's proving so popular already!

Who's Behind It?

The dream of two female triathletes based in London, Threo has quickly become the most talked about name in UK triathlon since its creation in 2014.

How did it come about? Laura and Rhian, the two founders, recognised the shortage of really well designed triathlon kit for women. At the same time they recognised the nonsense that is the cycling/triathlon 'divide'.

So they set out to design and manufacture kit that looked beautiful and distinctive without being garish, that fits real women perfectly, and that can be used by triathletes, cyclists, runners... in fact, by anyone who loves physical activity! They've worked miracles in creating a top notch brand whilst juggling pregnancy, motherhood and maternity leave, and the products are simply some of the classiest around.
