Alpinestars

Motorcycle properties, from a motorcycle maker

The line that separates it from a sportswear brand

The fabric does not melt under abrasion.

That is its own bullet, on a base layer. No other base layer in this catalogue addresses the question at all — not the training leggings, not the ski thermals.

It matters because a base layer is worn directly against the skin under riding kit, and many synthetics soften and melt under friction heat. The maker chose polypropylene with elastane, which binds little water and tolerates friction heat far better than polyester. The property claimed follows from the material chosen; it is not a coating that wears off.

The airbag

Its airbag vest is a motorcycle-specific system from a motorcycle maker — which is not true of most of that family, where the majority of what the shelf holds is published for equestrian use.

Its listing text, though, is brand, category, colour and size. Everything that decides an airbag purchase — the trigger arrangement, the coverage, the service interval, the cost after a deployment — is in the maker’s own documentation and not in what was sold on that page.
