What’s the best backpack in the 5,000+ cubic inch range?

Your Gearness, I keep seeing reviews for sub-5,000 cubic inch packs. Some of us get to wander the wilderness packing extra for the family or scouts, and we need bigger packs. What can you recommend for comfortably carrying 40 to 60 pounds in our beautiful mountains? Andrew Lehi, Utah


Yeah, you’re right. It’s true that today’s lighter loads (smaller tents, more compact sleeping bags, etc.) and the demographic trend toward shorter trips has somewhat reduced the need for ginormous, continent-swallowing, pack-enough-kit-for-a-month backpacks. But there’s still a place for that carry-anything pack, especially if you’re stuck performing as pack mule for others.

Cirrus Access FZ 7000 Backpack

These days a safe default choice for such a pack is the Marmot Astralplane ($399;, based on the classic Dana Gleason design from the 1980s. It’s still an extremely effective load-hauler, with a whopping 7,000 cubic inches of capacity in the medium-sized pack. The shoulder pads and waist belt are interchangeable for a semi-custom fit. And its Arc Flex frame system remains one of the most effective out there.

Gregory’s Whitney ($340; is another worthwhile big-pack contender. While not quite as cavernous as the Astralplane, at 5,450 cubic inches it’s still a big pack. It sports lots of pockets and tie-down points for packing efficiency. Most importantly, it has a way-above-average suspension, with light aluminum stays and a frame sheet for extra support and to protect your back.

A pack that doesn’t get enough attention in this category is the Cirrus Access FZ 7000 ($420; from Granite Gear, a relatively unheralded company that makes top-notch stuff. The FZ 7000 matches the Astralplane for gear-gulping capacity, with a little more modern design that incorporates a carbon frame sheet for light weight and efficient load transfer.

Dana Gleason, the wizard behind the Astralplane, is still around. His current company is Mystery Ranch (, based in Bozeman, Mont., from whence he launched Dana Designs back in the early 1980s. His flagship pack today is the G7000, an Astralplane-sized monster that looks an awful lot like the Astralplane, with its top pocket, long vertical back pockets, and big sleeping bag compartment. Gleason touts the pack’s “lumbar wrap" that helps stabilize and distribute loads of up to 80 pounds. Eighty pounds! That’s half a Gear Guy! I hauled that much to the Enchantment Lakes once. Never again. This pack ain’t cheap at $550. But it can carry the freight.
