Aegismax Quilt (Lengthened Ultralight Envelope Sleeping Bag)

The Aegismax Quilt E Lengthened is a lightweight quilt-style sleep system rather than a zippered mummy bag — the spec data lists it as a top quilt with a trapezoidal foot box, no zipper, and no hood. Fill is 95/5 goose down at 800 fill power (US standard), with 280 g of down giving a total weight of 508 g. The shell fabric is 20D nylon ripstop. Manufacturer-rated comfort of +11°C and a limit of +6°C place this firmly in summer-to-early-autumn territory; colder nights need an additional warm layer. At 200 cm long with an 80 cm shoulder width, it's cut to a standard unisex fit. Packed size is 20 × 12 cm, noticeably smaller than a comparable synthetic-fill bag, useful on ultralight loadouts with limited pack volume. The down isn't listed as hydrophobic or certified, and the product is made in China with a one-year warranty. Skipping the zipper and hood cuts weight versus a similarly warm mummy bag, but removes flexibility if temperatures drop unexpectedly — best suited to users comfortable securing a quilt to a sleeping pad.
