What to Compare Before Buying
- Size: Medium is the stated size for this version, so compare it with the sizing guide and your preferred fit.
- Set format: This is a matching top-and-bottom set, so compare it with a single thermal top or single thermal bottoms if that is what you need.
- Colour: The version shown is black, so check that the colour matches your preference before choosing an offer.
- Layering use: As a thermal base layer, it is worth checking that the cut and set format suit the clothing you plan to wear over it.
Before You Decide
Confirm the medium size, black colour and two-piece set format before choosing an offer. If you want only one thermal garment rather than a matched outfit, a different version will be a better fit.
