A jacket that masquerades as a flannel

I've used it several times
Size Bought:

Rather than a lined flannel, this is actually quite warm, like a micro puff jacket. Its kinda bulky, taking up much more space in a bag than a flannel, but considering it's really a jacket with buttons I am starting to bring it as my only jacket for spring evenings or mountain summer weekend trips. If you're tired of always wearing technical jackets to casual outings all year this is a nice way to roll with some more casual style and still be warm in the 40s/50s. Fits large enough to go over med layers like fleece, hoody, sweater, or even a slim fitting micro puff jacket. 4 stars instead of 5 because the pockets are not very secure, can't hold a phone while moving around. Otherwise very comfortable and useful.
