What the seller commits to paper

70% polyamide / 25% polyester / 5% elastane. Extra-flat seams for comfort and movement under jeans and a pullover. Deliberately placed ventilation panels for air circulation and heat regulation. The polyamide content stated to stop the fabric stretching out after repeated washing. A set of trousers and a long-sleeved top in three size bands.

Composition with a reason attached

Most listings that publish a composition stop at the percentages. This one says what the polyamide is there for — resisting the slow stretching that ends a base layer’s useful life — which turns a list of fibres into an explanation.

Flat seams, read for riding

The maker frames them for jeans and a pullover. Under riding kit the argument is stronger: a suit presses the base layer into the body at the shoulders, hips and knees, and a raised seam under three hours of that is what you remember about the day.

The rows this seller leaves empty

A fabric weight and a temperature range — the pair that says which season a base layer is for. One set in this family publishes both. And motorcycling is not among the maker’s stated uses, which are winter sport, walking the dog and a Christmas market.
