Bag Liner recommendations?

[Grumpy Goat]

Hi all,

I thought I could use my KTM SA-S bag for the left pannier, but, noooooo! Went on a trip like a hillbilly--multiple small bags and crap just falling out every time I stopped. Wanna get liners I can pack easily in house and then just slide into the panniers.

What do y'all use? Recommend? Recommend avoiding?

TIA

RKA liners. Work well and are cost effective. They are soft sided so they conform to whatever you can stuff into them and then stuff into the panniers.
