| Polyester |
Very good moisture transport and fast drying because the fiber absorbs little water. Performance improves with knitted channels or engineered surface finishes. |
Running, gym training, cycling, team sports, and high-sweat workouts. |
Lightweight and smooth; can feel clammy if the fabric construction traps moisture or if the garment fits too tightly. |
Generally strong, abrasion-resistant, and suitable for frequent washing. May retain body odors unless treated or washed properly. |
Machine wash according to the care label; use moderate temperatures, avoid fabric softener, and air-dry or tumble-dry on low heat. |
Choose a lightweight, open-knit construction for hot conditions and a brushed or layered construction for cooler training. |
| Polyamide / Nylon |
Good moisture movement and faster drying than natural fibers, although it can absorb slightly more moisture than polyester. |
Training garments, hiking, cycling, yoga, and activities requiring stretch and a smooth fit. |
Soft, smooth, and often more supple than standard polyester; commonly blended with elastane for stretch. |
High tensile strength and good abrasion resistance. Prolonged exposure to strong sunlight can gradually weaken some nylon fabrics. |
Wash gently, avoid excessive heat, and follow the care label to protect elasticity and surface smoothness. |
Select nylon when next-to-skin softness, stretch, and abrasion resistance are more important than the fastest possible drying. |
| Polypropylene |
Excellent liquid-water resistance and very fast drying because it absorbs almost no moisture. It moves sweat away when the fabric is properly knitted. |
Cold-weather base layers, endurance sports, and activities where low garment weight is important. |
Very lightweight and warm for its weight; may feel less soft and can hold odors if not treated or cleaned thoroughly. |
Adequate for base layers but less resistant to heat and some abrasion than polyester or nylon. |
Use low washing and drying temperatures; keep away from high heat because the fiber has a relatively low melting point. |
Choose it for a lightweight base layer in cool conditions, especially when rapid drying is a priority. |
| Merino Wool |
Moderate moisture absorption with good vapor management. It dries more slowly than most synthetics but can remain comfortable across changing activity levels. |
Hiking, outdoor training, travel, cool-weather running, and multi-day activities. |
Temperature-regulating and relatively odor-resistant; fine fibers are more comfortable than coarse wool. |
Less abrasion-resistant than nylon or polyester and may stretch, shrink, or pill if handled roughly. |
Use a wool or gentle cycle, mild detergent, low heat, and flat drying when required by the care label. |
Choose fine-gauge merino for comfort and odor control; avoid it when immediate drying after heavy sweating is essential. |
| Polyester–Elastane Blend |
Usually very good when polyester forms the main fiber; elastane adds stretch but does not significantly improve moisture transport. |
Compression wear, weight training, yoga, pilates, running tights, and close-fitting sportswear. |
Flexible, body-contouring, and comfortable for movement; fit and seam placement strongly affect comfort. |
Good everyday durability, but elastane can lose recovery when exposed to high heat, chlorine, oils, or prolonged sunlight. |
Wash cool or warm as directed, avoid bleach and fabric softener, and use low heat or air-dry to preserve stretch recovery. |
Check that the garment returns to its original shape after stretching and that seams do not restrict breathing or movement. |
| Polyester–Wool Blend |
Balances polyester’s faster drying with wool’s vapor absorption and temperature regulation; exact performance depends on the fiber ratio and knit structure. |
Outdoor endurance activities, hiking, trail running, and variable-temperature exercise. |
More temperature-balanced than a fully synthetic fabric and often better at managing odor during repeated wear. |
Typically more durable than pure wool, but abrasion and pilling still depend on yarn quality and fabric construction. |
Follow the more delicate fiber’s care needs; use gentle washing and avoid high heat unless the label permits it. |
Select this blend when comfort across changing temperatures and odor management matter more than maximum drying speed. |
| Bamboo Viscose |
Can absorb moisture and feel comfortable, but it generally dries more slowly than polyester, nylon, or polypropylene. |
Low- to moderate-intensity exercise, leisurewear, studio classes, and people prioritizing a soft hand feel. |
Very soft, smooth, and breathable; may become heavy or clingy when saturated with sweat. |
Lower wet strength and abrasion resistance than many synthetics; may shrink or lose shape if exposed to excessive heat. |
Use a gentle cycle, avoid high heat, and reshape while damp if the care label recommends it. |
Choose it for softness and moderate activity, not for the fastest drying during intense or prolonged workouts. |
