Great lightweight TShirt.

Lovely T shirts, I always size up a couple of sizes otherwise they’re skin tight. Lengthwise they’re perfect too as normal M&S T-shirts are not long enough. Wish they did them in Navy and Brown.

Very lightweight vests. Thin so are not too bulky underneath clothing.

Easy to wear, wash and dry. Easier to wear than long sleeves when it’s not freezing cold but chilly.

Ordered a size up as didn’t want too figure hugging. Super soft and stretchy, perfect to wear underneath jumpers, fleeces & shirts. Generates warmth as soon as worn. Washes well. Good product, well done M&S

I bought it for warmth. It’s not particularly warm and the vests are stretchy but ride up unless tucked in. Disappointed.

Perfect lightweight thermal

Perfect fit and long enough to tuck in. Keep me warm without being overly hot which I tend to be when wearing the long sleeved thermals. Pack small which is great for a weekend trip to Poland.
