Description

Part of our global boutique collection, this Unisex Seamless Thermal Underwear includes Free Tracked Shipping to the UK and US (Estimated delivery: 7–12 days).

Maintain Your Core Temperature in Freezing Weather

Layering up with bulky jumpers restricts your movement and completely ruins the silhouette of your winter clothing. This highly advanced thermal underwear set offers an incredibly thin, invisible solution. Engineered to maintain a constant 37-degree body temperature, it actively traps your natural body heat directly against the skin without adding any noticeable bulk.

• 37° Constant Heating: The specialised fibres act as a thermal barrier, locking in warmth to defend against sub-zero draughts.
• Traceless Seamless Design: The ultra-smooth construction ensures the garment remains completely invisible underneath your work trousers or casual shirts.
• High-Stretch Nylon Blend: Composed of 90% nylon and 10% spandex, providing exceptional elasticity that moves fluidly with your body.
• Transatlantic Defence: Whether braving a damp British winter or a freezing US cold snap, these thermal long johns provide absolute protection.
