What to Compare Before Buying
- Size: Medium is listed with a 84-89 cm waist. Compare that with the fit you need before choosing an offer.
- Warmth level: The stated 0.45 TOG rating gives a basic warmth reference. Check whether that level matches how you plan to wear the layer.
- Fabric blend: The 50% cotton and 50% polyester blend is part of the product’s make-up. Compare it with your preferred feel and care routine.
- Intended layer use: This item is presented as a base layer, so check that you want thermal bottoms rather than a standalone trouser.
Before You Decide
Confirm the Medium waist measurement against your fit needs, and check that the charcoal colour and thermal base-layer format are right for how you plan to wear them. If warmth level matters, compare the stated 0.45 TOG rating with the layer you want to use.
