Gossamer Gear Murmur 36 Hyperlight Backpack

The Murmur 36 is Gossamer Gear's laminate-fabric ultralight pack, built from ALUULA Graflyte V52 — a 100% polyethylene composite in the same family as Dyneema-style laminates, chosen for its strength relative to weight and its resistance to stretching and water absorption compared to woven nylon. The listed weight for this 36 L pack is 361 g, putting it at roughly 10 g per liter, among the lightest ratios in Gossamer Gear's lineup. Frameless and closed with a roll-top, it carries a webbing-only hip belt (no padding), a chest strap, one front pocket, and two side pockets, with no integrated rain cover — laminate fabrics like this are inherently more water-resistant than coated nylon, but seams and the roll-top still benefit from a liner in sustained rain. It's built specifically for thru-hiking ultralight setups where every gram counts and the hiker has already trimmed their base weight enough that a frame and padded belt are unnecessary.
