How to choose sportswear: fabric types (cotton, polyester, merino wool), compression vs loose, layering. Best brands and prices.

Sportswear fabric directly affects comfort, temperature regulation and sweat wicking. The wrong fabric can cause skin irritation, overheating or getting chilled.
| Fabric | Advantages | Cons | Best for |
|---|---|---|---|
| Polyester | Wicks sweat well, dries quickly, inexpensive | Can retain odor, less breathable | Most sports |
| Nylon | Durable, soft, abrasion-resistant | More expensive than polyester | Intense sports |
| Merino wool | Naturally antibacterial, regulates temp., does not retain odor | Expensive, dries more slowly | Running, hiking, cold weather |
| Elastane (Spandex) | Excellent elasticity, freedom of movement | Not used on its own (blended with others) | Compression clothing |
| Cotton | Inexpensive, comfortable, natural | Absorbs sweat, dries slowly, chills when wet | Light exercise, yoga |
