Our Verdict

The Gossamer Gear Murmur 36 Hyperlight Rucksack is a fantastic choice for ultralight backpackers seeking to minimise weight without sacrificing functionality. I’m a huge fan of GG packs; they prioritise simplicity, but that never impacts performance.  Constructed from 30 and 70 denier fabrics, this pack is designed to be light, making it ideal for solo missions or weekend summit bids where every ounce counts. With a total capacity of 36 litres and a main pack body capable of holding 28 litres, the Murmur 36 offers ample space for your essentials while maintaining a streamlined shape.

Equipped with a range of features to enhance comfort and convenience on the trail, the Murmur 36 boasts a roll-top closure system, a removable padded waist belt with integrated pockets, and unisex shoulder straps constructed from highly breathable mesh. The pack also includes removable Velcro loops for securing items, a large mesh pocket for quick storage, and stretchy back panels for holding a sit or sleeping pad. With a weight of just 356g and a maximum carry capacity of 9kg, the Murmur 36 is the perfect companion for ultralight backpackers looking to tackle challenging adventures easily.
