Comparing polyester and wool
A marketplace shortlist can hold polyester and wool at the same time. They are not interchangeable just because both can be cut into apparel.
What polyester contributes
Polyester is filed here as synthetic. One reason to open it is often practical for travel and workwear briefs. One reason to sample is breathability varies widely by construction.
Polyester pages should be read for construction and weight, not only for the fibre name.
What wool contributes
Wool is filed here as protein fibre. One reason to open it is recovery and crease behaviour useful for suiting. One reason to sample is warmth and itch perception vary by micron and finish.
Wool belongs in the shortlist only when its published construction fits the garment.
How to choose without a winner
Keep polyester when useful in blends and performance apparel is the constraint you cannot drop.
Keep wool when seasonal range from open summer weaves to dense coatings matters more. Leave GSM blank if the fabric page does not publish it.

| Family | synthetic | protein fibre |
| Often considered for | activewear, uniforms, linings | suits, jackets, coats |
| A strength to test | Often practical for travel and workwear briefs | Recovery and crease behaviour useful for suiting |
| A watchout | Heat and finish behaviour should be sampled | Open weaves may need lining for opacity |
Questions
- Is polyester always better than wool?
- No. The garment, construction and published weight decide. Reputation is not a spec.
