The players in my Felltower game debated either the "Icy Gate" or the "Forest Gate" for next session. Although they ultimately chose the "Forest Gate," the question of arctic gear (DF 16, p. 16) came up.
When meshed with DFRPG armor, it's a really good deal. Better DR for less weight than some non-metal armor. Assuming, that is, that it includes full coverage from head to toe.
Here is what I ruled:
Arctic Gear (DF 16, p. 16) includes coverage for the head (skull, face), torso, arms, legs, and hands. It does not include boots. It covers the face but not the eyes - for that, get snow goggles. Also gives +1 FP for heat when worn in in non-arctic conditions; otherwise as written.
Clothes don't generally include boots, so no boots. Nor do they include goggles, so no to goggles as well. The extra FP cost is to discourage people from using it as a general-purpose armor booster/ersatz lighter non-metallic armor.
It seemed like the most fair way to do it.
They went with the "Forest Gate" after all. So Al at Al's Arctic Adventuring Aemporium isn't terribly happy right now, but he'll be on standby with arctic clothing and snowshoes for next time.
