Shoulder Strap
Smart and feature-packed, but not perfect
The strap system on the 7L Sling is really impressive, and a feature of the sling the team spent careful attention on to maximize packability.
It’sfully removable on either side, giving you the ability to configure it however you like. Moment even designed it so the strap can double as a camera strap, which is a great concept in theory. However, in practice, the carabiner-style hooks are a bit too large to fit standard camera strap lugs (at least on mine). It’s a smart idea that just needs refinement, I'd think that slightly smaller clips would make it truly functional for most cameras.
On the strap itself, you get a long vertical zippered pocket that’s big enough for an iPhone or small wallet. Inside that pocket are two mesh stretch compartments, which is extra storage for smaller throw-away items like batteries, AirPods, or gum wrappers.
Other Criticisms & Suggestions
As good as this sling is, there are a few areas where I think Moment could make meaningful improvements:
Right-Shoulder Bias
The current design favors wearing it over the right shoulder. This feels like an unnecessary limitation, as many photographers prefer switching sides for comfort or access. If Moment adjusted the way the strap and stabilizer are mounted, it could easily become ambidextrous.
Missing Key Leash
There’s no key leash in the main compartment, which is surprising given that the rest of the Fast and Light lineup includes one. I was told a key leash will be added inside the vertical strap pocket in production models, which helps, but it would still be nice to have it inside the main compartment for quick access.
Strap Hooks Too Large
The carabiner-style hooks for the strap are a touch too big to fit standard camera lugs. Slightly smaller hardware would make the strap’s camera-carry function much more usable.
No Side Wing Pockets
The 4L version features side wings with exterior stretch mesh pockets, and I wish the 7L had them too. They add comfort and easy-access storage—perfect for things like snacks or cables.
Non-Waterproof Main Zipper
Since the bag is clearly aimed at outdoor use, the main compartment should really have a waterproof zipper. The material can handle light rain, but full waterproofing would make this bag way more prone to handle the elements.
