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. For Day 3 she's giving us the lowdown on the Mountain Warehouse breathe and balance high-waisted womens leggings. Remember to come back tomorrow for Day 4 of her week long challenge.

"These pockets are much bigger than the ones I tried yesterday."
