Carbon-lined Backpack

A bag cannot be airtight. It has zips, seams and fabric, so a smell proof backpack has to work a different way: a layer of activated bamboo carbon inside that holds odor molecules as air passes through it. That is why this one keeps working through a year of opening and closing. 16.5 x 11.5 x 5.5 inches, waterproof 1000D shell, integrated combination lock. $79.99, black.

HOW A SMELL PROOF BACKPACK ACTUALLY WORKS

Call it a smell proof backpack or an odor proof backpack, the mechanism is the same. Activated bamboo carbon lines the inside of the bag. Air on its way out passes through it, and the carbon holds the odor molecules. Nothing is sealed shut. That is the point, because a bag that had to stay sealed to work would stop working the first time you opened it.

A COMBINATION LOCK BUILT INTO THE BAG

The combination lock is built into the bag itself, three dials on the top edge with the zipper pulls clipping straight into it. Set your own three-digit code. That is the difference between a backpack with lock hardware designed in and a bag you add a padlock to afterwards. It keeps the bag shut in a shared house, a locker room or a car, and it keeps children and pets out of anything you would rather they did not reach.

16.5 X 11.5 X 5.5 INCHES, WITH A PADDED LAPTOP SLEEVE

Full-size, so it works as the bag you already carry rather than a second one. The padded sleeve takes a laptop. There is also a large front zip pocket, two exterior side pockets and two interior pockets. Everything has somewhere to go.

SEAM-SEALED ZIPPERS, WATERPROOF SHELL

1000D polyester outside, seam-sealed zippers. Rain stays out. The seal also closes the gap a standard zipper leaves, which is where odor escapes on most bags that claim to stop it.

IT DOES NOT ANNOUNCE ITSELF

Plain black. No logo across the front. Nothing that reads as anything other than a backpack. Discretion is most of the reason to buy a bag like this, and branding it loudly would undo it.
