Winter gloves -- Glacier Gloves

[markannas]

I  just got a pair of Glacier Gloves as a Xmas gift.  I mtbike commute to work in Helena, MT where the winter air tends to be cold.  These gloves, unfortunately, do not work well insulating against the air.   I ride at 10-12 mph, and if there's any wind, add that to the windchill.    The air temp for my morning commutes have been in the teens.  Halfway through my commute yesterday, had to stop, and get out my mitts, I had fortunately brought along in commute bag.   On another trip, put them under my Izumi lobster mitts, which was fine....gave me an extra layer against the wind, which warmed my hands some, but defeated the purpose of the Glacier Gloves.  Would seem they may be better suited for warmer temps.  Tip to designers - if you wish to make them a true cold weather, waterproof glove, increase the fleece thickness, and add just a breath of thickness to the glove digits if one wishes to wear a polypro liner for extra warmth.

As a scuba diver, I can attest to the effectiveness/ineffectiveness of neoprene. The most effective way neoprene works is to allow a small amount of water to enter, the body warms that water, the glove limits water exchange, and the overall system is very effective in storing heat. If water does not enter the glove (or wetsuit), that region of the body will be cold. If too much water moves in and out, that part will also be cold.

The same glove in 40F temps will be ineffective if dry, but very effective if wet inside with no water exchange. Ideally, a small amount of water enters, the body warms up that water, and everything stays warm.

My most effective cycling mitten is a Pearl Izumi PRO. It is, however, a sensitive mistress. Above 28F, my hands sweat uncomfortably. Down to 18F, my hands are just right. Below that, I need supplementation, e.g.  pogies. YMMV.
