Stabilizing Strap

The strap works very well. It’s like to use it when riding bike. I rated 4 stars because I find the price a bit high for a small accessory. But I am still happy to have it

Keeps my bag from falling forward from off of my back when I bend or lean forward! Super convenient.

Toshi Sling 6L V2 に使用して使っています。
専用設計で、基本的な機能は押さえており使いやすいです。
一つだけ改善して欲しいところは、ロゴパッチを手触りの良い布地に変更してほしいです。固めの布地で、手触りがチクチクするのと、ショルダーストラップの布地を傷めそうです。

Nice and simple stabilizing strap. Even includes a strap keeper so you don't need to deal with dangling straps. Love that it stows into the same cavity as the external carry straps when not in use. I just wish I had thought to order it at the same time as the bag so I didn't have to pay shipping.

I like carrying the sling frontwards. Didn't like how the stabilizing strap isn't really well designed for that style of wear. Also im a big bodied guy and it is too short for me.
Overall disappointing purchase but not worth sending back.

Also please sell 6L strap cushion separately so I can add it to my 5L sling strap.

I added the Stabilizing Strap to my setup, and it’s one of those upgrades that quietly makes a huge difference.

What I love most is how much it improves carry stability—especially when I’m on the move. Whether I’m biking, commuting, or just walking quickly through the city, it keeps my sling securely in place without any annoying shifting or bouncing. It makes the whole experience feel more locked-in and comfortable.

The design is simple but really well executed. It’s lightweight and low-profile, so it doesn’t add bulk or get in the way when you don’t need it. At the same time, it’s easy to attach and detach, which makes it super convenient to switch things up depending on how you’re using your bag.

The materials feel just as premium as the rest of the system—durable, reliable, and built to handle daily use. The adjustability is also spot on, letting you fine-tune the fit so it feels secure without being restrictive.

Overall, the Stabilizing Strap is a small addition that makes a big impact. If you’re using a sling regularly, especially in more active situations, it’s absolutely worth it for the added comfort and control.
