- Pack quantity: The product is marked as a pack of 2. Confirm that this matches the number of sets you want.

- Fabric mix: The blend is 50% cotton and 50% polyester. Compare this with your preference for feel and care needs.
Before You Decide
Check the X Large size, the black colour and the pack of 2 format before choosing an offer. If the TOG rating and fabric blend are important to you, make sure they suit how you plan to wear the set.
Check the Fit for Layering
When checking the size, consider how both pieces will sit under the clothing you plan to wear over them. If sizing information is available for the selected version, compare the top and bottoms separately with your preferred fit, including sleeve and leg length.
