A tough backpacking rucksack with tons of extra features. The stiff frame allows a heavy weight to be carried in this pack and wide hip belt transfers the load efficiently.
For multi-day endeavors in the mountains, the Graviton 34 is the smallest in this new series. At 35-liters, this pack epitomizes minimalist travel in the mountains. Newly designed zippers allow you to access the entire main compartment to locate an item without having to unpack everything. This pack features a breathable airflow suspension with a tubular aluminum frame and a padded waist belt, making it comfortable to carry.
It's hard to believe the weight of Marmot's Graviton 34 Panel Loader Backpack when you see how comprehensive the back panel and carrying system really is. The back panel itself is moulded stiff plastic with an ergonomic shape, this is supported by a metal rail which runs round the sides and bottom of the framesheet. It's incredibly supportive and will allow you to carry a lot of weight.
There are 3 main points where the pack meets with your back, two points between the shoulder blades and one at the small of your back (in line with your hips). The rest of your back is free to breathe, kept away from the rucksack with mesh. We don't stock too many packs that do this, as this set-up normally adds a lot of weight to the pack. Marmot have achieved a very breathable back system at a minimal weight penalty.
Feature-wise the Graviton has it all and more, large lid pocket, extra-large side bottle pockets, front stash pocket for wet gear & a front opening zip panel that allows access to the entirety of the pack.
The hip fins are nice and wide giving a lot of support, they've got good sized zip pockets on both sides too.
