Good, solid product that has many uses.


  • Many available sizes
  • 2 openings
  • lightweight

I have about 3-4 of these in varying sizes on my pack and I love them. They can be used for just about anything, from clipping on a water bottle to securing flashlights. They are really easy to use and its double openings make it a breeze to clip on. They are durable and lightweight, and I don't worry about them breaking at all.

Overall a great product that I highly recommend.


One of the best backpack / keychain accessories available.

One of the best backpack / keychain accessories available. The flexibility and practical nature of the S-Biner allows for countless applications. Usage ranges from securing keys to a belt loop to hanging a lantern or water bottle from my pack.


  • Small
  • Durable
  • Practical


  • No locking mechanism
  • Spring clip is a weak point


The S-Biner is a straightforward piece of gear. The dual hook nature allows a user to latch objects to other objects. The spring clip makes this task super easy, and keeps the attached item secure. 


Due to the simplicity of the S-biner, there isn't much to talk about. The device is composed of two hooks in an "S" shape. A metal wire acts as the clasp, and is mounted in such a way that it springs closed. The clasp is very easy to open and close. 


The S-Biner can take the abuse within reason. There is a weight rating associated with the size of the S-Biner, and it should be considered whenever a significant load is placed on the device. The metal spring clasp, however, is delicate and can come loose if the S-Biner is abused or stressed beyond its intended weight range.


I use these devices every day and everywhere to secure lightweight objects to my person, my backpack, or other objects. From the city to camp to trail, the S-Biners are up to the task as long as you do not exceed the weight limit by a great amount.

Purchased the Nite Ize S-Biner #3 and is advertised that it should hold up to 25 lbs. I plan to use it with my PCT Bear Bag system. I hope it can hold a group bag, but for the price let's give it a try! 

They are super lightweight at 1.1 oz and very functional. They're great for clipping on a drybag, a light, extra gear or nearly anything. Due to the dual ended design, they can be woven into strapping to provide two lash points (one up, one down). 

I also have these in the #2 and #4 sizes, which are also useful. I find the #3 to be the perfect blend of compactness and usefulness.

The Size 2 S-Biner is small enough to be used as a key chain carabiner, but versatile for lots of different uses. The S-shape keeps items at both ends from tangling, keeping things seperate and organized. Great for securing two zippers on the same track together on backpacks or suitcases.
