- I don t know if we have had a prior thread on this, other than people talking about how they fit a particular can into a particular pack, usually just statingMessage 1 of 32 , Jun 14, 2013View SourceI don't know if we have had a prior thread on this, other than people talking about how they fit a particular can into a particular pack, usually just stating whether it fit or not, and whether horizontal or vertical.My take on this:1) Bearcan, when packed, tends to by pretty heavy and will probably be the most weight-dense thing your carry. In fact, if you can place it efficiently you may want to consciously concentrate the weight in the bearcan, replacing lighter food items (like dried soups) with heavier non-food items (like water, fuel) while moving.2) Very important that the bearcan does not wiggle around (which can happen if it is lashed above a pack, particularly a frameless pack). If it is shifting with every step, you will use your muscles 1000's of times a mile to bring it back into place. Therefore any arrangement should hold it very firmly in place. It can be very tiring otherwise.3) Most efficient place for heavy items is as close as possible (consistent with comfort) to your spine and fairly high. However, you don't want it so high that it makes you top heavy. Probably weight centered at about the mid shoulder blade level is best. Overly high placements also tend exaggerate any step-by-step shifting of the can, raising the issue in (2) above.4) You want to make sure the can does not interfere with head movement. If it's bumping the back of your head as you walk, or forcing you to keep your head too far forward, it's gets unpleasant fast. My least pleasant day of hiking ever was caused by bad bearcan placement that made me keep head just a bit too far forward.5) How you do this will be highly specific to your particular canister and your particular pack.6) You can also distribute weight internally in the can, concentrating the heavier food items (e.g., olive oil in a bladder, couscous, cornmeal, hummus, Clif Bars) and high as possible and on the side of the can that will end up forward. Lighter items (oatmeal, dried soup, instant rice) can be lower in the can and closer to the side that will be rear-ward.7) My 16 inch (custom size) Bearikade fits vertically in my MOLLE 2 backpack with the top of the can about midneck. I've rigged some strapping inside the pack so that I can hold it snugly against the rigid frame.John Curran Ladd

I searched through the archive folders and could not find a saved folder on this discussion point. If there is one, will you please send me to correct folder?
If not... can we talk about how to carry a bear canister? Not pack, but carry...
We're planning to carry a BearVault 500 and a Bearikade Weekender. We have Granite Gear Escape 60 back packs.
Outside or inside the pack? If outside, suggestions of how to attach it?
Where on the outside or inside have folks found carrying it to be the most comfortable, less taxing? High? Low? Middle?
Anything else to add, please feel free... and thanks, in advance.

- Pumping into the Bearikade is not useful; what you need is a vacuum pump. Bearikade seals only when outside pressure is higher than inside pressure. UnderMessage 32 of 32 , Jun 18, 2013View SourcePumping into the Bearikade is not useful; what you need is a vacuum pump. Bearikade seals only when outside pressure is higher than inside pressure. Under certain circumstances, it will self-seal. On a recent trip, I took from sealevel to 10,000 feet and back to sea level. When I opened it, there was a rush of air going in.
