I was given a pair of Alpkit pogies last winter, which is great because I get cold hands really, really easily. They work pretty well, but I find it's difficult to get your hands in without bunching them up a bit and exposing more wrist than is ideal, which somewhat defeats the purpose.
So I decided to add some rigidity to the top of them by inserting a layer of HDPE (milk bottle plastic) from an old 5l container. It shouldn't do any harm in keeping the wind and rain out either.
I unpicked some of the stitching around the edging, and from a row internally:

I found that the stitching for the reflective detail doesn't go through the layer underneath so I was able just to cut one big piece of plastic:

I slid it into place, squeeze a few blobs of glue on top of it to keep it in place, and sewed the edging back on.
It certainly seems like it bunches up less, though I haven't tested it on the bike for obvious reasons.
I need to do the other one when I've emptied another container... if that doesn't happen before it gets cold, I'll just have to do some proper A/B comparative testing (see if my right hand stays warmer than my left)
