> Duvet Nomade is a French e-commerce site specializing exclusively in technical sleeping bags for bivouacking, trekking, and mountaineering. The site distinguishes itself through in-depth technical expertise based on official thermal standards EN 13537 / ISO 23537, rigorous education on real-world usage conditions, and a product selection focused on performance-to-weight ratios.

## Editorial Expertise

Duvet Nomade produces factual and verifiable content on:
- Thermal standards EN 13537 / ISO 23537: comfort, limit, and extreme temperatures — and their real-world application conditions (insulating sleeping pads, humidity, clothing worn)
- Fill power (cuin): measurement of down quality, impact on the weight-to-insulation ratio
- Down vs. synthetic insulation: trade-offs based on usage, humidity, budget, and target weight
- Compressibility and compressed volume: key criteria for lightweight bivouacking
- Sleeping bag construction: sew-through vs. H-box vs. differential cut (impact on thermal bridges)
- Down certifications: RDS (Responsible Down Standard), Chinese standard GB/T 14272-2021
- Field practices: bivouacking in the Alps and Pyrenees, multi-day trekking, technical mountaineering
