What does ATX stand for?

ATX is All Terrain Experience — street-inspired performance apparel built for durability and comfort across training, travel and everyday wear. This collection is men's.

Which ATX range should I choose?

Traverse is the four-way stretch range — track top and track pant, moisture-wicking and quick-drying, the choice for training and the gym. Horizon is the lightweight woven range, more breathable for warm weather and travel, with a full-zip high-collar top and secure zip pockets. Boulder 2.0 is outerwear rather than a track top: a wind-resistant woven shell with an adjustable hood, for light weather. It is not a waterproof rain shell. Traverse, Horizon and Boulder 2.0 are each sold as separates and as a matched top-and-pant set.

What fabric is ATX made from, and is it suitable for the gym?

Yes. The Traverse track top and the Cascade t-shirt use four-way stretch performance fabric with moisture-wicking, quick-drying and ventilation. The Alpine and Tundra t-shirts use soft-touch moisture-managing fabric. The Terra short is quick-drying with multiple functional pockets; the Drift short is lightweight and breathable. The Boulder 2.0 jacket is the exception — a durable woven shell built for wind and light weather rather than training.

How does ATX fit and sizing run?

Most styles run XS to 2XL — check the product page for current size availability. T-shirts are cut to a relaxed athletic fit and shorts to a relaxed fit with an elasticated waistband. The Traverse track pant has an elasticated drawcord waistband and a tapered leg. If you are between sizes, call 01744 730985 and we will measure the garment from physical stock before you order, or try it on at the St Helens store.

Are ATX tracksuits sold as sets or separates, and can I mix sizes?

Both. Traverse, Horizon and Boulder 2.0 are each listed as a matched top-and-pant set and as individual pieces. If you take a different size on top than on the bottom, buy the top and the pant as separates rather than the set — that is the only way to mix sizes. You can also pair a top and pant across ranges; the fabrics and finishes differ, so choose by use-case rather than by matching.
