The Enlightened Equipment Enigma 10 850 is a zipperless top quilt with a permanently sewn-closed footbox, aimed at cold-footed sleepers who want maximum warmth for minimum weight. Dropping the zipper and hood cuts weight to the essentials — you lose the ability to open it flat into a blanket, but gain thermal efficiency from fewer seams and openings for heat to escape.
This variant is listed in the Regular size (fitting users up to 183 cm); EE also offers Short and Long lengths for it. It's filled with 526 g of grey duck down at 850 fill power, and a differential cut helps the loft distribute evenly. The manufacturer's 10°F (-12°C) rating and 692 g total weight put it in winter and demanding three-season territory. The shell is 10D nylon ripstop with a DWR finish.
The down is RDS-certified, the quilt is made in the USA, and it's available in navy. A good match for taller hikers heading into colder conditions who prefer a simple zipperless design over the versatility of a hybrid quilt.
