We have a week of 7 Day Challenges for you and the first one today features Bellatrix from Canada who's looking at thermal leggings from a couple of brands throughout the week. It can get to 30 degrees below zero where Bellatrix lives so who better to review these. The first leggings are the Mountain Warehouse Talus womens base layer pants in navy for her to try on for you all. Remember to come back tomorrow for Day 2 of her week long challenge.

"These very much have an under garment look to them like long johns and I like how they have a tapered leg." Bellatrix
