La Sportiva Ascent Primaloft Vest Black

Pertex Quantum
Pertex Quantum is a tightly woven yarn among one of the lightest, high-performance fabrics on the market: a lightweight soft fabric, that even though is very lightweight, allows for a high level of insulation and abrasion resistance.

Made with incredibly fine yarns, Pertex Quantum fabrics were designed to improve the efficiency of insulation and breathability.

A durable water repellent (DWR) finish sheds light rain and snow to provide additional weather protection. 

Vapovent
Layered construction system adopted for high sweating areas: allows optimal breathability by encouraging the escape of humidity. The external layer is made of water-repellent material while the Primaloft padding is insulating.

Primaloft Insulation Thermoplume
A water-repellent, thermal fabric made with a silky fiber that provides loose-fill insulation.
