TOPS
Endless ways to layer, work out and go about your day, from fitted tees to oversized sweatshirts. Define, Accelerate and Refined cover the essentials, with sculpting, oversized and cropped fits. For warmer sessions, Dynamic and Challenger bring you lightweight vests and tanks, while Aire, Align and Prime offer sweatshirt layers that feel more considered than a traditional sweat, while still being made to move. Pair your favourites with our loungewear edit for an effortless off-duty look, or explore our training and Outdoors edits to build the rest of your kit.
Every top is fabric-led rather than one-size-fits-all: Define offers a fitted, second-skin feel made for training, while Motion and Cruise bring a softer, more relaxed feel for downtime. For warmer sessions or easy layering, Form and Flow keep things lightweight and breathable. Horizon, with its long-sleeve design, is ideal for those in-between days when you want a little more coverage without the extra warmth.
Layer up. Train hard. Wear it out.
The Tops collection is a genuine mix of fits and styles, designed to work across training, layering and everyday wear. You'll find fitted, sculpting styles like Define, alongside oversized and relaxed fits such as Accelerate and Dreamer. For warmer sessions, Challenger and Dynamic offer lightweight tank and vest options, while Aire, Align and Prime are sweatshirt styles, designed to bring a more elevated, considered feel to your everyday and training wardrobe. Whether you're looking for a training tank, a fitted layer or something more relaxed for downtime, there's a style to suit.
For training, look to our fitted and vest styles, Uplift, Form & Flow, built with a closer fit for freedom of movement. For everyday wear and downtime, Dreamer Tee, Aire, Cruise and Prime offer softer, more relaxed fits that work effortlessly beyond your training sessions and sit closer to the feel of our loungewear collection. Whatever your day looks like, there's a top to match it. Browse our training pieces and our Outdoors edit to see how they pair with the rest of your kit.
It depends on the style. Our fitted tops, like Define and Raise, are designed with a closer, sculpting fit, so take your usual size or size up for extra room. Our oversized and sweatshirt-style tops, like Accelerate, Aire and Prime, are cut generously by design, so you can size down if you'd prefer a neater fit. Full sizing notes are on each product page.
Our fitted tops like Define offer a sculpting, second-skin fit designed to move with you through training. Our oversized styles, including Accelerate and our sweatshirts, are cut with more room through the body for a relaxed, effortless feel that works well both on the go and off duty. Both are made with the same considered approach to fabric and quality, it's the cut and fit that sets them apart.
We want you to get the most out of your tops so you can wear them for years to come. As standard, we advise washing cold, inside out, and avoiding tumble drying for all ATIA pieces. Please refer to the instructions inside each garment for optimum care guidance.
