We appreciate that there are some people who find it hard to stay warm in the cold winter months and with the cost of living putting pressure on some households, we wanted to take a look at some thermal underwear this week. So Sophia Smith has a 7 Day Challenge for us and for the final day. She's brought us a curved ball today as these are not thermals, instead she's reviewing some Primark 200 denier opaque tights for us. So which was her favourite from this week and do you agree with her? Find out at the end of todays review. Filmed in 4K.

"I often wear tights under my trousers to keep warm during late Autumn through to early Spring."
