When it comes to staying warm in the winter months, adding layers doesn't always cut it, but investing in thermals could help you stay warm when out and about.

As many gear up to get outdoors beginning with Boxing Day walks, wrapping up warm is vital, and Uniqlo is one of the best known retailers for affordable thermals.

The Japanese high street brand has slashed the price of a popular thermal fleece top in a limited-time offer. The HEATTECH Fleece Crew Neck T-Shirt is reduced from £19.90 to £14.90 - but hurry as the offer ends on December 22.

For delivery in time for Christmas, you'll need to order by 23:59 on December 19, but if you're not in a rush, you'll have a few more days to take advantage of the deal.

The comfortable top comes in six shades, and is designed with technology to lock heat in, so it's ideal for wearing as a layering piece, or alone as a long-sleeved top.

Uniqlo shoppers are leaving reviews on the handy piece, with one saying: ''This thermal keeps me so warm, especially when I am on my bike. I wear it underneath jumpers and with a light jacket on top and it’s perfect.''

Another commented: ''This crew neck shirt is just perfect for winter, it will keep you warm and it’s not bulky if you wear if underneath your outfit!''

However another Uniqlo reviewer gave a warning about the sizing, saying: ''Slightly tight fitting, otherwise soft and warm. Thinking of purchasing in other colours. Probably will go for medium size instead of small.''
