What to Compare Before Buying
- Size: XXL is part of the chosen variant, so check it against the size chart and your preferred fit.
- Set format: This is a top and long johns set, so compare it with whether you want a full base layer or a single garment.
- Fabric feel: The stated blend includes polyester and spandex, which is useful to note if you prefer a particular stretch or fabric mix.
- Lining: The fleece lining is a key part of the design, so consider whether that matches the level of warmth you want from a base layer.
Before You Decide
Confirm the XXL size, black colour and two-piece set format before choosing an offer. If you need a different fit, compare the size chart and make sure the long sleeved top and long johns match what you want from a thermal layer.
