Best duck down backpacking quilts

Top pick: Paria Thermodown 15 — 800 fill-power duck down, 20 oz of fill in a 20D ripstop shell with a PFC-free DWR, and the highest owner rating of the bunch. It's the quilt I'd hand most three-season backpackers: warm enough for shoulder-season nights without a big weight penalty.

Who the others suit:

• Paria Thermodown 30 — same duck down build, lighter and cheaper; best for summer and warm-weather trips.
• Neve Gear Waratah UL Summer Quilt — 850FP duck down at 435 g total; for gram-counters who sleep warm. Ships from Australia, so duties may apply.
• Featherstone Moondance 25 — a 36°F comfort-rated top quilt with a zipper footbox; good if you want a roomier, more versatile cut.
• Therm-a-Rest 20F Down Quilt — ISO-tested ratings (20°F limit, 32°F comfort) if you want a number you can trust; the priciest here.
• Sea to Summit Ember EB3 — a 45°F no-zip quilt for fast-and-light summer trips.
• Naturehike 0°C quilt — 550FP duck down; the budget entry point, heavier for the warmth.
• EMS Dusk 350 — a low-cost duck down quilt for occasional use.

Skip the VIAM, OneTigris and SENSORY4U quilts if you specifically want duck down — they don't state duck down fill.
