A lightweight, breathable mid layer that bridges the gap between fleece and base layer. Soft, stretchable, and exceptionally comfortable, the Stellar Light Mid Sweater keeps you warm without overheating and moves moisture efficiently during high-intensity activity — from winter tours to summer runs.
How it fits into your System

Warmth without the weight.
The Stellar Light Mid Sweater is a versatile, lightweight layer made from Japanese Fieldsensor™ fleece — a technical fabric that blends soft comfort with efficient moisture management. Its variable-density construction pulls sweat from the skin and disperses it across the outer surface for rapid evaporation, keeping you warm when you pause and dry when you push harder. Stretchable, smooth, and refined to the touch, it works equally well for ski touring, fall hikes, summer running, mountain biking, or everyday travel. Breathable warmth, low bulk, and reliable durability make it an easy layer to reach for year-round, whether worn on its own or under a shell. Comfortable enough for daily use, technical enough for demanding mountain days.
How to use it
A lightweight layer for easy layering when a classic fleece feels excessive. Thinner, less warm, and more stripped-back than the core midlayers, it is built for moisture management, mild weather, and thermal fine-tuning. Choose it when you want a breathable extra layer without bulk.
