Key Details

Detail Product information and buyer relevance
Set contents One long-sleeved top and one pair of thermal bottoms.
Brand and model LNFINTDO, model SL349+SL494-LF-UK.
Size and colour Size L, colour variant Grey Line. Check the fit before choosing this size.
Fabric Polyester and elastane; the proportions are not specified.
Construction and design Single layer without fleece lining, with a mock-neck top and a close-fitting design intended to sit beneath other clothing.

What to Compare Before Buying

  • Fit: Check the size guide and garment measurements against the fit you want. A close-fitting layer may feel different from a looser top and bottoms.
  • Layering: The set has no fleece lining. Compare its single-layer construction with the thickness you need beneath your usual clothing.
  • Set configuration: Confirm that you want both the long-sleeved top and bottoms, rather than just one base-layer piece.

Who This Product May Suit

This two-piece set is intended as a men’s base layer. The listing names activities including skiing, running and cycling; the close-fitting top and bottoms can be worn under other clothing for those activities. Suitability will also depend on the fit and the rest of your clothing layers.

Important Limitations

The set is single-layer and has no fleece lining. No fabric percentages, garment measurements or care instructions are specified, so check the selected size and care label before use and washing. The listed fabric composition alone does not establish a particular level of warmth or moisture management.

Before You Decide

Check that size L is the right fit, that Grey Line is the colour variant you want, and that a single-layer set with a long-sleeved top and bottoms suits your layering plan.
