With the Dynafit TLTs, my entire ski setup weighs less than my daughter's downhill skis, but I can bomb through crud with ease on a slope. In a word, these bindings are tough. I can climb all day, easier than climbing in snowshoes, and the pivot is perfect, it feels like a natural gait. These bindings are deceptively simple but so well designed that you will LOVE them.


  • Light and strong


  • If heels are locked in for downhill, it can be difficult to unlock the heel without removing the skis.
  • Can be hard to line up toe holes

I started out Alpine Touring with Silvretta 500 bindings, and I liked them. I was reluctant to upgrade, but after researching Dynafit TLT bindings, I was convinced to go with them.

The Dynafit bindings are a design marvel, so simple but extremely versatile. The front clip holds fast to the boots, and the heel height adjusters are elegant and work perfectly. These bindings have yet to release unexpectedly or break when bombing down the mountain. They feel like an extension of my legs. 

These bindings may look too small to stand up to abuse, but they are super strong. At 6' tall and 200 lb, I can be hard on equipment, so the fact that I have had no problems with these bindings is pretty amazing.

I have been skiing with these bindings for three years now and have used them on Snoqualmie Pass, Sevens Pass, and Hurricane Ridge. The skis that I use these bindings with are older Dynafit, which are narrow and light, I am considering getting slightly wider, heavier skis to use with the TLT bindings, but every time I check out a pair of new skis, I imagine lugging that weight up the mountainside and I change my mind.

As I mentioned in the Cons section, when your heels are locked in, the only way I have figured out to remove them is to take the skis off from the toe clip. It can be difficult to get the toe holes in your boots to line up and snap in place, but it's getting easier with practice.

They work. Light weight. Secure holding when locked down.


  • Light weight
  • Secure


  • Brakes not large enough

Enjoyed using these bindings this last winter. A few challenges learning how to get locked in and managing the steps but after the second trip, things were good. You can, with a pole tip, turn the heal piece all the way around to switch from walk to ski or back. Took some practice.  

Though I am a lightweight, have no problems carving the hard pack on the way back to the lodge. These are much better than the clunky first pair of bindings I had.
