The lightest design in Montbell's rucksack roster, the Versalite Pack 40 is an ultralight backpack that still manages to pack in the features. That ballistic nylon ripstop keeps the weight right down without sacrificing strength, there's side-pockets for your bottles and a strap to keep those trekking poles firmly in place. It's packable too-making it a great travel option for stowing in a holdall on a big adventure, ready to be deployed up in the hills.
