Great Quality!

We bought these again due to the old ones were good quality, the fabric was soft and stretchy. It lasted my son for a few years. We bought it good value and was easy to collect fr local store. Only take a couple of days. Would recommend!

Excellent quality and price

Yes, I recommend this

I buy these children's thermal tops for myself. They are excellent quality, warm, comfortable and have kept their shape after many turns in the washing machine. I'm a woman's size 8 and buy the 11/12 for a snug fit or the 13/14 for a looser fit.

Great quality and super cosy in the cold!

Yes, I recommend this

Bought it for myself and they are exactly what I wanted. Crew neck, good length, not tight or loose (I am a size 8) and right thickness to layer up or wear in bed. Lovely soft material that makes a very cosy wear.
