The North Face 3-In-1 HyVent Waterproof Ski Snowboard Hooded Jacket-Blue-Men's S

-A 3 in 1 jacket typically consists of a waterproof and breathable outer jacket, also known as a shell, plus a warm, fleece-style jacket on the inside. They can be worn separately or zipped together, giving three possible configurations – perfect for changeable weather. -The main benefit of a 3 in 1 jacket is its versatility – it can adapt to suit all weather conditions when you're out. Wear the fleece alone when it's cool and dry, or wear the shell alone when it's wet. If it's cold and wet, wear both. -HyVent was The North Face's former brand name for a waterproof, breathable fabric technology, which has since been replaced by DryVent. HyVent used a polyurethane (PU) coating to provide waterproof protection and durability, while allowing moisture vapor to escape, keeping the wearer dry and comfortable in various weather conditions
