It's not loose but there is room to layer if that makes sense. PM a contact info and I will snap a photo wearing the jacket if you want. Awesome jacket but the unpronounceable FL puffy was what I asked for from my wife. The sanctuary is just too warm to move in. It's like wearing your sleeping bag. Not as heavy or bulky as I thought it would be for how hot it is. Actually you probably could actively hunt in it if it's -30 degrees but otherwise you would probably sweat out in 5 minutes. Tree stand all the way. The fusion Camo is great but since I rarely hunt in snow in California I actually took a brown and olive green permanent marker to my stormtight set, northbranch, and puffy to "calm down" the white so it looked more like the tanner merino gear. The sanctuary is not super white like the stormtight, northbranch, or puffy. It's probably cause it's softer fabrics and super quiet.
