Are thermal wheel skirts worth it?

I recently purchased an 8×16 Yetti. I am now debating on getting the Hardkor Outdoors Thermal Wheel Skirts. They look well made, but I don’t know anyone that has them. Are they worth the price? I already have the hole sleeves for the Catch Covers, will they block enough or should I get the skirts as well?

When there is snow, use that to bank the house.

My wife is going to sew up a skirt set for our wheelhouse (8×16 Grey Wolf) before this ice season. They definitely come in handy when there isn’t a ton of snow to bank with to help keep the wind from blowing under your house, which can bleed a lot of heat.
