When buying an outdoor or functional vest, you should consider pack size, wind resistance, breathability, and insulation. Lightweight softshell vests made from Dynastretch have a small pack size, are breathable and windproof, making them perfect for intense activities. Insulated vests keep you really warm, but they’re less compact and work great as an extra layer under a jacket or in colder conditions. The choice of vest depends on the area of use and personal needs.
