Average.
No, I don't recommend this
They aren’t as stretchy as I’d like and go baggy on the knees after only a couple of hours wear. I expected more for £28.

My legs are toasty but too long!
Yes, I recommend this
V Good Quality have purchased item before - slightly short in leg for me. I’m 1880mm high but going up a size would probably mean I’d have to eat more grub and be a fatty to absorb the excess material forming the overstretched elastic waist bit.

Winter Wear
Yes, I recommend this
I purchased these thermal under garments for additional warmth during this winter period. I am approaching my 80th birthday and feel the need for extra clothing during the cold days. They are comfortable to wear and do provide extra insulation against the cold temperatures. Recommended.

Yes, I recommend this
These are brilliant! I was looking for something to complement a lighter pair of trousers that I want to wear in cooler conditions and these are it! I've even worn them with winter cords to boost the warmth factor. They're close-fitting, comfortable and a superb purchase.
