These are very easy to use and do not come loose! I highly rate these straps with the softrack solutions Green Chile offer.
Sometimes the more simple the better. This is the case here with the Soft Rack Side Straps + Bag Snake Kit to carry ANY dry bag (30L for us) on the sides of our bike. It installs and fits perfectly with an aftermarket luggage rack on the tail of my KTM 690 enduro R and my girlfirend's Honda CRF 300L Rally.
But on top of fitment of the bags, it just simply works to hold them there, any conditions!! The binder feature of both the Soft Rack Side Straps and the Bag Snake Kit does the job, period.
And when you don't need to carry luggage, you just take it off in litteraly 2 minutes.
Awesome product, thank you
