Are cap straps compatible with other binding brands?
Are they good for splitboard touring?
These are solely for burton bindings. Yes they will work just fine for splitboard touring.
Most people that use them with other brands just rig them... I have done about 10-15 cap strap conversions in my day and they are pretty simple as long as you don't mind running some franken-style... and get creative with a dremel tool!
