Sea to Summit Cinder Down Quilt 35

The Sea to Summit Cinder Down Quilt 35 is a lightweight down quilt without a hood or a fully enclosed underside — the quilt concept relies on the sleeping pad for insulation, with pad loops attaching the quilt to the mat. This removes the weight of down that would be compressed and non-insulating under body weight anyway. The 300 g fill of 750-fill-power goose down sits in sewn-through chambers with horizontal orientation — simpler and lighter than box baffles, with a slightly higher risk of cold spots along the seams. A manufacturer-rated comfort temperature of 2°C and limit of -4°C place it among three-season products for milder weather, working out to roughly 155 g per degree at 620 g total. The NanoShell outer is a 20D nylon, waterproof-breathable with DWR treatment, and the liner uses a softer 20D nylon. A cinching cord at the foot end closes the footbox as needed. A sensible pick for lightweight summer trips where the quilt trade-offs — no hood, open sides — are acceptable for lower weight than a conventional bag.
