Please refer to my review written for https://backpackinglight.com/atompacks-prospector-rucksack-review-first-looks/
I feel that the AtomPacks Prospector is a very good rucksack, especially as you can have it made exactly how you want it. It is made with quality materials and should last well.
I think the rucksack was good value for money. But as they are made to order, delivery could be a while depending on AtomPacks’ workload. Mine took nearly 2 months to arrive, but it was well worth the wait.
