BARELY fits the Sarkens. Pretty frustrating... especially when it's cold and windy and you're tired, etc. etc.

It's a durable bag with a mesh side which helps prevent rusting.

That said, there are better options.

My cyborgs fit in them... barely but it does keep them in as tight of a space as possible which is nice for packing them. You do need to be careful of the points. The mesh top is nice for keeping things aired out but I would still take my crampons out to dry after a day of climbing. The bag is much easier to use than point covers.

What can I say about a crampon bag? This one is pretty basic - no daisy chains or useful lashing loops so good luck strapping it to the outside of your pack if that's your style. Personally, I either use a crampon bag inside my pack, or strap my crampons bare-toothed to the outside of my pack so that doesn't bother me. However... the bag is a little small. Mine measures 10.5 x 5 x 4 inches, so if your crampons are any larger than that, no soap. The mesh is a little stretchy (at the cost of somewhat damaging the mesh) so I've managed 10.5 x 5 x 5 but that is about the max. My old CM 12's and CAMP's fit fine, my alumimum Stubai's barely barely fit (frustratingly tight), and my fixed rail ice crampons don't at all. And the bag weighs 7 oz (almost as much as one of my aluminum crampons) so I mostly only use this while packing my crampons in my luggage. But for that purpose, when crampons fit in it, it's bomber and has protected my gear quite well...

This bag is a tight fit even for my Petzl crampons in their smallest setting. You also need to make sure that you have all your points properly positioned or you do run the risk of one of those points threatening to push through the material portion of the bag (although I haven't experienced it happening, it looks like a matter of time before I do). The mesh top is a great feature as is the hanging loop so that you can dry them off in the bag. If I were to do it over again, I'd probably get point covers instead.
