I hear the poc bug receptor is warmer / heavier. The shiv is downrtight light. I own it.......but when I got my shiv you could only get it in like 3 colors.....so if you need to look like a skittle...you will find a bug receptor in your color thats for sure.
Yeah, pretty much what he said. And when you go to try it on, make sure you bring a beanie if you want to wear that under, and your goggles. It'll help you decide what you want.
