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 have another Under Armour item for Day 5 as she checks out these women's UA tactical base leggings. Remember to come back tomorrow for the penultimate day of her week long challenge.

"It says that I can tear off the label, oh I love that, it just comes straight off!" Bellatrix
