Choose a mummy-style bag for your next camp sleep setup. This Letu listing names white duck down fill, a 10D nylon outer and a 7D nylon lining, with black and yellow options across several S, M and L model selections.
The current options list S models 410, 640, 860 and 1090; M models 450, 700, 950 and 1200; and L models 500, 780, 1050 and 1330. The number in each option is a model identifier here, not a verified fill weight, total weight or temperature rating.
The imported product information identifies a 10D nylon outer, 7D nylon lining and white duck down filling. The source calls the outer tear-proof, but does not provide a test standard for that claim.

Adult campers comparing down mummy bags who can confirm size and temperature suitability for their planned conditions.
The imported fill specification contains damaged text around a claimed percentage and fill power, so neither figure is stated here. No tested temperature rating, finished weight, packed dimensions, body-fit measurements, water-resistance rating or down sourcing certification is provided. Do not infer warmth or fill mass from option numbers. Keep the bag dry, follow the care label and confirm your selected variant's measurements and independent temperature documentation before relying on it outdoors.
The supplier packing list specifies one outdoor sleeping bag; it does not expressly list a storage sack.
No tested temperature ratings are supplied. Treat the numbers as model identifiers until the manufacturer provides further documentation.
The listing shows these size labels but gives no fit dimensions. Confirm the chosen model's measurements before ordering.
Check the selected model's fit and weather documentation before purchase.
