The zipper starts on the bottom when you're wearing the sling pack

After stuffing it with dryer sheets and sending it through the dryer a couple of times followed by a few days of airing out in the closet, the smell was finally tolerable enough to use

I have owned hundfeds of bags similar to this, pro and nonpro, amazon and nonAmazon

Use it for riding (I prefer the single sling arm strap) and it works great

Pleanty of space in this compact design

I am able to fit all my EDC needs without thinking or wondering if anything will break or go wrong
