The Enlightened Equipment Conundrum 30 850 is a 3-season quilt built around a sewn-closed footbox and a 3/4-length side zipper, a middle ground between a fully open quilt and a zip-up bag. At 612g total with 377g of 850-fill-power duck down, it's rated to a -1°C limit, putting it in the 30°F class its name suggests, and it packs down to roughly 35 x 18cm for a 6.5-litre stuffed volume.
The shell is 10D nylon ripstop, continuous vertical baffles keep the down evenly distributed rather than shifting into cold spots, and a draft collar plus draft tube seal the open side against cold air infiltration — a detail that matters more on quilts than on closed bags. The Regular cut suits average-height hikers rather than taller or shorter builds specifically.
Handmade in the US with RDS-certified down and PFC-free treatment, this is a solid 3-season choice for backpackers who want the weight savings of a quilt but still like the security of a partially closed footbox and collar.
