The problem with pogies, and it can be a serious one, is that if you take your hands out and submerge them in really cold water, they become pretty useless in a relatively short length of time. Fingered gloves just aren't warm enough. Mittens are comparable to pogies in warmth but you lose a lot of fine motor finger dexterity because your fingers are encased. I was out boating with a pair of the NRS mittens and had to remove one glove just to wipe fog from my glasses....a major hassle.
Enter....the mitten modification. Hunters you mittens with this modification all the time because they also know that mittens are the warmest form of glove. Simply by slicing an opening across the palm of the glove right at the base of the fingers you can remove any number (up to four of course!) of fingers from the glove and effortlessly return them to the warmth of the glove. Since the slit is always against the paddle shaft almost no extra water enters the glove. Even when submerged my hands stayed warm and any water that does enter quickly drains. IMHO it 's the best of both worlds between pogies and gloves. I could easily use my fingers for such mundane chores as putting on my skirt, clipping in items and the all important relieving myself all without removing my NRS Toaster Mitts. Below is a link to pics of the modification.
