Patagonia 2019 Atom 8L sling pack mates well with the clip on Nitecore NU25. Using the logo embossed strap below the shoulder pocket (new 2022 model doesn’t work), the clip fits perfectly and very securely. Depending on how you wear the sling, it will point straight ahead or just a bit downward. Adjusting the tilt on the clip, it will light up the area ahead of your feet. Hope this topic is in the proper forum.
