Long underpants Glovii GP1RXL Red Unisex Adult 490g

Glovii GP1RXL long underpants in red are heated thermal base-layer trousers for adults, offered as a unisex model and designed to retain warmth during cold conditions. Constructed from a stretch blend of 94% polyester and 6% elastane, these long underpants combine flexible fit with thermal performance. The garment integrates carbon-fibre heating elements positioned to support the lower back and knee areas, and includes a pocket to accommodate the Li‑Ion battery that powers the heating system. At a product weight of 490 g, the GP1RXL provides a balance of insulation and mobility suitable for active outdoor use and extended wear.

Advantages

The carbon-fibre heating elements emit infrared waves that contribute to improved local circulation while delivering consistent warmth. The polyester-elastane fabric is thermoactive, allowing quick moisture absorption and supporting the efficiency of the heating system. A dedicated battery pocket facilitates secure and convenient placement of the Li‑Ion battery, and the garment’s unisex cut accommodates a range of body shapes. The placement of heating zones around the loins and knees ensures targeted and even heat distribution without restricting movement.
