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. We change brands for Day 4 as Bellatrix gets to try out the Under Armour women's ColdGear® authentic for you all. Remember to come back tomorrow for Day 5 of her week long challenge.

"They do feel really soft and oh the inside is lined with this beautiful soft fabric." Bellatrix
