I’m not bashing ya. I can totally relate to losing sled clothes. Good thing you didn’t lose yer boots. You can always sled without gloves, but you can’t sled without boots. Well, ya could but it would suck! I hope you find some mittens for your digits!
Sometimes the hotels will have lost and found gloves. Maybe you can select a pair from there.
You might be stuck with whatever they sell at home hardware or the drug store. I forgot a balaclava a couple years back and was SOL. Alpine in Valemount is likely the closest option for actual sled gloves.
