Looking inside the 1L sling you get quick access to your keys, a pen, and a cord pass-through in case you want to charge your devices on the move. On the outside, there is a convenient easy-access pocket for smaller items. This amazing sidekick also includes water-resistant, tamper-proof zips for protection and security, as well as a reflective bar for visibility in the dark. Carry it like a fanny pack or cross body, in the front or in the back, as you commute, hike, or travel through any of life's adventures. I use this for about a week or so on a very short trip. I try and ship next day but sometimes it might take up to three. I have a bit of a chronic pain thing going on, so please be kind.
