Yep, it costs a fortune but this is one sweet jacket. I use it for a daily bike commute in Minneapolis where it's often 0 degrees or less during my 8 mile ride to/from work. I tried several "biking jackets" but none were big enough or ready for brutal cold.
I wear a thick long-sleeve UnderArmour base layer, thick fleece mid-layer, and the Stinger. I ride comfortably in the brutal cold, no problem.
The collar is HUGE but I love it. As others have noted, one can bury one's face right in it. It's also great (necessary) that the hood is enclosed (they catch air when biking ).
As for sizing, I'm about as big as they come: 6'7" and 275 athletic build (54 XXLT suite with 38" waist). I bought the XXL and it's a perfect fit; plenty of length. The "body" is not tight/fitted but that's good for me as I need to layer to survive. Enjoy!
