When you heard of the Crown Royal Tank, you probably imagined a purple army tank, blasting whiskey jugs into people's homes. Sorry to disappoint, but at least it's a pretty cool women's base layer top from Burton. This midweight base layer is a waffle-knit poly/cotton blend with moisture wicking properties. It's made for inbounds riding where you prefer comfort to techy features. The cotton in the blend means it'll be way more comfortable than polyester long underwear, but it'll take a little longer to dry out.
