Product Description

The Nimbus Core Pack from Granite Gear introduces a completely new concept in backpack design--offering hikers and climbers greater versatility for carrying hard to pack and bulky gear such as bear canisters. Beginning with the quest to develop a pack that would meet the challenge of packing and carrying a bear canister securely, the Nimbus Core features two full-length lateral pockets that cinch around whatever you choose to carry in the pack's core. In addition to carrying a large bear canister this turns out to be a versatile system for lots of different loads that can be hard to fit inside a conventional pack including tripods, fly rods, wet tents, and/or compressed items like sleeping bags. After filling the core, the Nimbus Core's compression flap cinches tight from the top, bottom, and sides to hold your load securely and efficiently.

The Nimbus Core introduces a new suspension system from Granite Gear that combines their Advection back panel with their Topoflex frame sheet for ergonomic weight distribution and cooling. The Topoflex frame sheet follows both the vertical and horizontal contours of the back, allowing for a more consistent load distribution leading to better blood circulation and less muscle fatigue. The suspension is The suspension is engineered with three distinct zones of flexibility--a shock absorbing lumbar zone; a semi-rigid mid-back zone for even weight distribution and the perfect level of torsional flex; and a rigid upper zone that accommodates the load lifters to pull the whole load close to your back. The Advection back panel features foam panels that allow air to flow freely between the back and the frame sheet to allow for evaporative cooling.

Offering exceptional versatility and flexibility for outdoors people of all stripes, from bear country hikers and climbers, to fishermen, hunters, and photographers, the Nimbus Core makes carrying cumbersome and bulky objects comfortable and hassle-free. Backed by Granite Gear's strong record for creating long-lasting outdoor gear, the Nimbus is covered by a lifetime warranty against defects in material and workmanship.

How to Measure Your Torso to Choose the Best Back Pack Size:
To find your torso length, measure the distance between your seventh cervical vertebra and the shelf of your hipbones. Do this by standing up straight with your feet shoulder-width apart. Tilt your head forward and place your hands on your hips, thumbs to the back. With a flexible tape, have someone measure from the most prominent vertebra at the base of your neck to an imaginary line drawn between your thumbs. This will be your torso length.

Please note: Each framesheet has fine adjustment settings spaced in one inch increments to further fine-tune your fit. If you are a 17-inch torso, it is recommended to try the short torso first.

Product Description

A completely new concept in backpack design. This Pack started out with our quest to develop a pack that would carry a bear canister securely. It does a nice job of this but in testing this piece we've found it's a sweet and versatile system for lots of different loads. There are two full length lateral pockets that cinch around whatever you place in the CORE of center section of the pack, then a compression flap can be cinched down tight holding everything securely in place. We've found this center CORE section also works great for many other items that are hard to fit inside a conventional pack -- tripods, fly rods, wet tents, as well as compressed items like sleeping bags.

Color Name: Burnt BrickSize Name: Reg Torso Verified Purchase
I bought this pack, hoping to replace an older, panel loading Granite Gear pack that I absolutely adored (Nimbus Latitude). There was little in the way of information, but I thought I would take the risk and see if I liked it. I did not, so I returned it.

First, the pack is not that big. I would estimate 3200 cubes, at max. If you want to carry a bear canister, and precious little else, then this is the pack for you. I don't carry a bear canister, but after putting my compressed down sleeping bag, pad, a rolled up jacket, and food in the main compartment, there was no more room left. I could have jammed more stuff inside, but the panel that covers the compartment is only so big. If that panel was wider, it would have been better.

The main compartment has another flaw, in my opinion, there is no true bottom to it. The pack is basically the two side pockets with a flap that goes between them.

Also, the compression straps are attached really strange. They are mounted opposite of each other. You have to pull both sides to the right to tighten them down, instead of the more logical arrangement of pulling them towards each other. Also one of the bottom buckles is attached to a 1 inch strap and you need to feed the other side underneath the stretch pocket to get to it. This is nearly a herculean effort when the bag is packed to capacity, which it will be, because it's so small.

Despite it's flaws, it seemed well made. I was a big fan of padding and overall comfort of the pack. I was really disappointed overall, I really wanted to love the pack, but I ended up hating it and returning it.
