I haven't seen their Pogies. In addition to weight (a minor factor in my view), you should consider ease of getting your hands in and out of them. And, they should tend to stay in the same place on the shaft, rather than sliding down when you take a hand out.
I have some old Stohlquist Pogies with lightly waterproofed Nylon material. The waterproofing is also somewhat heat reflective.
Frankly, though, this old geezer deals with the issue by only padding on days when the afternoon temperature reaches 55 F, and the wind is relatively low. I usually have my waterproof camera on my person, and so I don't like to fool with Pogies and the camera too. To keep my hands tolerably warm, I over-insulate the rest of me. That causes blood to flow to my hands to compensate for my body being almost too warm.
