Separate material approval from the sleep-system rating
A sleeping bag combines shape, baffle design, hood, draft protection and filling distribution. Specify the intended temperature-performance assessment and evaluate the complete product. Avoid turning a filling value into a comfort claim.
Composition and loft considerations
A down-rich blend and higher loft target may be candidates for a compact design. Choose them against a tested weight and packed-volume brief; availability and performance must be confirmed.
Contact us for specification and available fill power ranges. Use a consistent method, units and conditioning protocol to compare candidate lots.
Testing and destination-market requirements
Identify the destination market and exact standard edition. EN, JIS, USA-2000, KS, GB/T, QB/T and CNS requirements can be discussed. Material testing and finished-product testing serve different purposes; neither should be assumed to cover the other.
Qualify a sample before scaling
Assess the proposed filling in the actual construction. Record the approved material lot and test results, and agree how future lots will be accepted. Confirm sample dispatch, lead time and packaging for your order.
Specifications, samples and quotation
CIRCUDOWN supplies recycled duck down, goose down and feather to agreed purchasing briefs. There is no minimum order quantity. Material samples are free, with shipping paid by the customer. Send your requirements to request a specification proposal, sample arrangements and a quotation; lead time is confirmed per order.
What to include in your inquiry
A target is a request for review, not a confirmed available grade. CIRCUDOWN confirms the proposed material, test requirements, price and lead time before order approval.
- End use: jacket, duvet, sleeping bag or another construction; share a specification sheet if available.
- Duck or goose down, white or grey appearance, and target down content with its definition and tolerance.
- Fill power target, unit, test method and conditioning procedure; say if these are still to be decided.
- Required testing standard and edition, certification or recycled-content claim, and supporting documents.
- Estimated quantity and unit, delivery destination, sample needs and requested delivery date.
