ThruDark Mantra Gilet

The ThruDark Mantra Gilet is built for those who demand warmth without restriction. Designed as a high-performance mid-layer, it delivers reliable insulation while maintaining freedom of movement—ideal for mountaineering, trekking, and cold-weather pursuits.

Crafted from Polartec® Thermal Pro®, this synthetic fleece recreates the comfort of shearling but with far greater durability and technical performance. It traps warmth efficiently while remaining breathable and fast drying, making it a dependable choice for multi-day expeditions. The anti-pilling properties of the fabric ensure the gilet keeps its shape and look over time, even with repeated use in rugged environments.

The design is finished with a high collar and chin guard for extra protection against the elements, and a low-profile fit that layers easily under jackets without adding bulk. Three secure external zip pockets and additional internal stowage offer space for essentials. Underarm side panels made from Polartec® PowerGrid™ increase stretch and ventilation where it’s needed most, enhancing comfort during high-output activity.

From alpine ascents to cold morning starts, the Mantra Gilet delivers the technical warmth and versatility to meet every challenge head-on.
