Training apparel

Gym clothing covering training shirts and singlets, shorts, tights and leggings, hoodies, and accessories such as caps and socks. The practical difference between training apparel and ordinary clothing comes down to fabric and construction rather than appearance.

Fabric is most of it. Synthetic performance fabrics such as polyester and nylon blends move sweat away from the skin and dry quickly, which is why they stay comfortable through a session. Cotton absorbs sweat and holds it, which feels heavy and cold afterwards. Flat or offset seams matter more than people expect, since seams in the wrong place are what causes chafing on longer sessions.

Looking after it

Wash performance fabrics in cold water and skip fabric softener, which coats the fibres and destroys the moisture wicking that you paid for. Air dry where you can, since high dryer heat breaks down elastane over time and is the usual reason leggings lose their shape.

Frequently asked questions

Why does my gym gear smell even after washing?

Synthetic fabrics hold onto the oils that bacteria feed on, and normal washing does not always shift them. Washing cold without fabric softener helps, as does a periodic soak in a vinegar solution. Leaving damp kit in a bag is what causes the problem in the first place.

Should I avoid fabric softener on activewear?

Yes. Softener leaves a coating on synthetic fibres that blocks moisture wicking and traps odour. It is the most common reason performance fabric stops performing. Use a normal detergent and skip the softener entirely.

Is cotton bad for training?

Not bad, just different. Cotton absorbs sweat and holds it, so it gets heavy and stays damp, which is uncomfortable on longer or hotter sessions. For lifting in an air conditioned gym plenty of people prefer how it feels. For running or anything sweaty, synthetic performs better.

How do I stop chafing?

Seam placement and fit, mostly. Flat or offset seams, and a close fit that does not shift, prevent the rubbing that causes it. Loose cotton on a long run is the classic combination to avoid. For endurance work an anti chafe balm covers the rest.

How should I wash and dry it?

Cold wash, no softener, and air dry where possible. Dryer heat degrades the elastane that gives leggings and compression gear their stretch, which is why they go baggy. Turning items inside out before washing also helps with odour.
