Both pairs had holes on one knee from stacking in my skates last winter. I figured with all this cold weather about it was time to sort this! One pair is a set of Endura thermastat, and they are extremely warm, I can pretty much only use them at 5 degrees celcius and below. Anyone got any recommendations for a medium warmth set of biblongs, preferably Endura? The Endura 3/4 biblongs I have are too much to the other extreme and are not warm enough.
