The Problem Solved

With the fluffy jacket on, I literally just felt warm. It was like I was snuggled up in a blanket in winter watching TV. The gap actually fluctuated between the two. At one point around the 20-minute mark, I was 37.3 in the jacket, 38.6 without the jacket. So it was like a full degree 0.3 difference. Well, I suspect because when you're wearing that blanket, you're going to delay like a tintilation. But yeah, it's exactly the same out.
