Ethical Down Standard (RDS) Certified Our commitment to ethical practices is reinforced by our adherence to the Responsible Down Standard (RDS). This international certification guarantees that our down comes from ducks and geese not subjected to live island harvesting or force-feeding. Each batch undergoes traceability audits to ensure humane treatment throughout the supply chain.

Premium Construction for Ultimate Durability Crafted with a robust 5D nylon outer layer, these sleeping bags are waterproof and resistant to wear and tear. The inner liner and muffler are made of high-quality 5D bonjie fabric, offering excellent moisture absorption, breathability, and smoothness. The sponge fabric adds extra warmth, lightness, and durability while maintaining quick-drying properties and superior elasticity.

Innovative Insulation Design Featuring a layered sealed structure, this design prevents feather displacement, ensuring consistent warmth. Accurate down filling is guaranteed through rigorous dummy testing in real test chambers, aligning with ergonomic principles. An internal circulating heat zone further enhances insulation, keeping you warm even in the coldest conditions.

Convenient Storage and Maintenance Each sleeping bag comes with a stowage bag for regular use and a storage bag for long-term preservation. When arriving at your destination, simply remove the sleeping bag from the stowage bag, shake it to fluff up the down, and enjoy immediate comfort. For extended storage periods, keep the bag in its stowage sack, avoid placing heavy objects on top, and hang it up to maintain its fluffiness and warmth.
