Comfortable and breathable

Yes, I recommend this

Comfortable but thiner than expected. I purchased large which fit well but i may purchase a larger size to give a denser colour to tights when worn

Disappointed

I bought these in medium but find them rather small. I am only 5' 3 with a small frame , size 14 so medium should be a good fit.

They fit well but they smell a bit funky, I’m keeping them cause you can never have enough thermal tights

Winter Warmth!

Yes, I recommend this

These were a comfortable fit with plenty of stretch. I wore them with a knee length knitted dress and my legs didn't feel the cold at all... So, the Thermal Heatgen really works! I bought the brown and the grey for diversity in my Winter wardrobe. There is a size chart on the packaging to help find the correct sizing, which was helpful and accurate. The pricing was reasonable, as they wash well and keep their shape... So, should last more than one Winter :0)
