The Analog Variant technical shirt/spring riding jacket. The ATF (Analog Technical Fashion) series was born with the idea that progressive style can be totally functional & technically sound. This may not be traditional 'outerwear' but it has special detailing & treated fabrications that may not be apparent at first glance. What appears to be a traditional flannel shirt is in fact a reversible technical riding top with a quilted 80gm poly insulated reverse & treated with a DWR water repellent coating to the plaid side. Ideal for spring riding & fine weather on the hill.
