FAQ
Start with the expected overnight low, then account for your sleeping-pad R-value, shelter, clothing, wind, humidity and whether you sleep warm or cold. ICEFLAME temperature guidance is developed through team field testing and real-world customer feedback. Because sleep systems work as a whole, use the published figures as a practical selection guide rather than a guarantee of individual comfort.
RDS (Responsible Down Standard) addresses animal welfare and chain-of-custody requirements for responsibly sourced down. It helps customers identify products made with certified material. Check the individual product page to confirm whether RDS-certified down is specified for that model and fill option.
Fill power measures down loft and insulating efficiency—higher FP (like 700) means more warmth for less weight and smaller pack volume. For ultralight backpacking, a higher FP gives better warmth-to-weight performance.
Hydrophobic down resists moisture longer than untreated down but is not fully waterproof. It helps reduce loss of loft in damp conditions, but you should still keep your sleeping bag dry with a waterproof shelter, tent footprint, or dry bag.
Spot-clean small stains and air out your bag after trips. For full cleaning, use a front-load washing machine with a down-specific detergent and low-heat tumble dry with clean tennis balls to restore loft, or use a professional down cleaning service.
R-value measures thermal resistance. For three-season camping choose pads with R ≈ 2–3; for cold or winter use pick R ≥ 4.0. Combine pad R-value with your sleeping bag rating to ensure overall warmth.
Balance weight vs. protection: ultralight tents save grams but may trade off convenience, interior space, or storm performance. For alpine or 3000m use choose designs with strong structure and reliable materials; always check seam taping and waterproof ratings.
Manufacture time is typically 3–7 business days (some sizes may take longer). International transit to carriers takes ~3–5 days; EU shipments route via our European warehouse—delivery (including customs processing) typically takes about 2–3 weeks. EU customers usually do not pay import taxes; final delivery is handled by local couriers such as DHL or DPD.
We accept returns for unused, unopened items in their original packaging across our entire store. Before returning any product, please contact customer service to obtain a return authorization and the correct return address. Some items (for hygiene or safety reasons) may be excluded from returns—customer service will confirm any exceptions when you request a return.
