I’ve used a Stashsafe 100 for years. I needed something bigger and tried the Vibe 100, but it was too bulky and the Roobar, while clever is a nuisance if you need get into the bag alot, which I do. The GO gets it right for me. A good size. Less bulky. Not camo. And much easier to open. I realize the bag might be slightly less secure, but If I’m using the bag, I am wearing it. I don’t need the kind of security that lets you lock and walk away from the bag. Security-wise I need a slash-proof strap and body, and a slightly more difficult zipper opening, like the zip-clip. This bag has those things.
The waist strap connection is an improvement for me too. I always struggled with the PopnLock which is very clever, but not intuitive. I rarely used it which kind of defeats its purpose. The clasp on the GO Sling Pack is sufficient: it takes 2 hands that know how the thing works and will slow any thief down long enough for me to protect my stuff.
Three suggestions: (1) I have the navy blue bag with yellow zipper pulls. The yellow is a nice accent color, but why advertise where the zipper pulls are? I replaced them with black zipper pulls. (2) I miss the back zipper pocket that the StashSafe 100 has. (3) The GO is very comfortable as a cross body, but I usually wear it on my waist and that leaves alot of waist strap flopping around. It would be nice if there was a clip to secure the extra length.
All in all, it’s a great bag!
