We've been using these for quite a while too, and really like them. They work really well with our system. Namely, a small string of horses...Horse Saddle Panniers with poly liners
Anybody have experience with this style of panniers? For guys that do not own there own stock and rent horses....could pre-pack and weigh each poly liner ahead of time and not take a chance on the condition of rented equipment.www.rokslide.com

I have used this one for 5+ years ....with the poly inserts. The poly inserts make a significant difference if using to pack camp in.....I weigh each pannier to within 0.5 pounds....so it doesn't shift. I don't use the H top pack. Instead I use 2-36" green military duffel bags (sleeping bag, clothes, food) - 1 on top of each poly insert. Then, I use ratchet straps across the top of the saddles using the metal d rings on the panniers to secure them and to lift the panniers off the sides of the horse. It has a a belly strap to help secure the panniers. This setup has worked well for 5+ years.
If using the poly inserts, use the panniers that have the reinforced bottoms and corners....will help the panniers last a longer and resist wearing holes in the corners if the horse brush up against trees.
