I bought this cantle bag for my English saddle. Once you get it properly attached (I placed the straps under my stirrup millets with no problem), this product is excellent for long trail rides. The two water bottles are a real plus and the holder is slightly insulated so Im not drinking warm water on my ride. There is room for an extra jacket so long as you roll it tightly and it isnt too bulky. Ive also found room for some emergency equipment. It stays in place. We would buy again. Its lightweight and easily rinsed off with water.
