Do Filson Feather Cloth shirts stop mosquito bites?
Filson’s personal experience is that mosquitoes cannot bite you through our Feather Cloth, but that isn’t going to stop mosquitoes from getting to you through the open neck or the cuffs of your Feather Cloth shirt. Will Filson Feather Cloth fabric protect me from UVA and UVB radiation? This is a question that some fishermen ask when considering a purchase, so Filson tested their Feather Cloth fabric for its Ultraviolet Protection Factor (UPF). UPF is a rating for apparel, similar to Sun Protection Factor (SPF) for sunscreen. UPF measures the ability of a garment to block harmful UVA (Ultraviolet Aging) and UVB (Ultraviolet Burning) rays. Filson found that the UPF varies, depending on the color. • Desert Tan has a UPF 15 rating. • Light Blue has a less than UPF 15 rating. • Olive Green, Burgundy and Taupe all have a 50+ UPF rating – the maximum rating possible.
