Until the Tough Puff I never would have called myself a 'shacket guy'... I figured you either wear a jacket or you don't... so either did - or didn't. Then the Tough Puff came along and my world was changed. I would definitely call this closer to a shirt than a jacket. I tend to run on the warm side of things and this is great for cool mornings and warm afternoons... inside and/or out.
First off, this thing looks slick... I mean classy. Just as much at home on the hill as it is in the pub. Face fabric is durable enough to wear as an outer layer and not worry about abrasion, technical enough but with none of that techy vibe.
Works great as a layering piece when it's under a shell. I've worn it out on the river a time or two now under my waders and it has kept me warm and comfortable the whole time on the water.
Zippered chest pocket gives you a safe and secure place to store your small and important items. Two hand pockets are great to warm hands up real quick, and two big drop pockets on the inside... well... I haven't found a great use for those yet, but I have no doubt that there is one.
As far as sizing goes... a little wonky there. The Tough Puff runs a full size large.
