Ultimate Cold Weather Performance for Ultralight Alpine Adventures
Struggling with bulky bags that fail in true alpine cold? Most sleeping bags just don’t cut it when you're pushing past 6000m.
Enter the ICE Flame SD1000 NXT. Engineered for 3-season ultralight expeditions and 7000m-level mountaineering, this bag delivers relentless warmth without the weight. Stuffed with 1000g of 800FP Muscovy duck down and constructed with a full 3D box baffle system—top, bottom, and sides—it locks in heat where it counts.
Wrapped in 10D ripstop nylon with a high-density DWR finish, it blocks wind and sheds moisture while remaining breathable and skin-friendly. No PFOA. No PFOs. Just pure alpine performance.
Whether you're summiting or snow camping, this bag compresses small and performs big. Shop with confidence—Ice Flame's insulation is IDFL-tested and backed by real-world alpinists.

RDS Certification
Ice Flame sources down that complies with the Responsible Down Standard (RDS) wherever possible. RDS certification ensures humane treatment of birds and full traceability from farm to finished product.
| Certificate No. | Certified Weight | Issue Date | Seller | Buyer |
|---|---|---|---|---|
| 200.00 kg | 2024-11-08 | Guangdong Kulida Down Products Co., Ltd. | Anxin County Ice Flame Outdoor Down Products Co., Ltd. | |
| 200.00 kg | 2025-03-19 | Guangdong Kulida Down Products Co., Ltd. | Anxin County Ice Flame Outdoor Down Products Co., Ltd. |
Note: RDS certified down increases product cost. For premium 900FP down, due to the small quantities sourced, the cost of RDS certification often exceeds the value of the down itself, making it impractical to certify.
Smell Control
Ice Flame uses mature goose and duck down—not down from young birds—and processes it in-house with high-grade detergent to remove grease smell without masking agents or perfumes.
Fill Power & Insulation Quality
Ice Flame selects down from cold climate regions to ensure maximum loft and insulation performance. No chemical additives are used to artificially boost fill power, making our gear more sustainable and longer-lasting.
| Fill Power | Type | Composition |
|---|---|---|
| 820FP | Goose Down | 92% White Goose Down (IDFL tested) |
| 700FP | Duck Down | 85% White Duck Down (IDFL tested) |
| 800FP | Goose / Muscovy Duck Down | Premium untreated fill |
| 900FP | Goose Down | Small batch, high-end (not RDS certified) |
