Mountain Laurel Designs Burn

The Mountain Laurel Designs Burn is a frameless, roll-top ultralight backpack with 38 L total capacity split across a 25 L main body, a 5 L extension collar, and 8 L of pockets — one front and two side stretch-mesh pockets. At 467 g it works out to roughly 12.3 g per liter of capacity, and the maker lists a recommended load ceiling around 11-12 kg, typical for a frameless pack where comfort under heavier loads depends on how the load sits against the wearer's back. The body comes in UltraGrid 200D ripstop or the more premium Ultra X 100 fabric, both DWR-treated. Features are kept deliberately minimal: a padded, non-removable shoulder strap, a webbing-only hip belt that can be removed entirely, side compression straps, two ice axe loops, and side loops for trekking poles, but no daisy chain, no hip belt pockets, and no integrated rain cover. It's aimed at experienced ultralight thru-hikers with an already-lean base weight, for three-season trips of roughly three to five nights, where every non-essential gram and feature has already been designed out.
