I bought these for my suzuki kingquad 750 . I’m able to carry a lot more in them then I thought . I had a pack shovel, 20 ft tow strap, 4 bottles of water, bug spray, ton of bungee cords and a couple 1 inch ratchet straps. It still had some room but was close to full . I did not use the phone carrier as I am not willing to take the chance of it falling off, although it hasn’t . 120 miles of rough terrain so far with them. They hold up to a pressure washer as well. As long as they are zipped up water stays out. Overall they’re a great add on if you don’t want to lose rack space and save some money Only downside is the zippers are awful

Very helpful

Lots of pockets. Easy to attach to rack on 4 wheeler. Heavy durable material. Only complaint is some zippers are hard to operate. This is due to they are made to be waterproof. Not really a problem since I seldom close the zippers.

I bought these bags for my 2022 CanAm Outlander. They are a hair too short to use the buckles on the front fender but fit like a dream on the back fender. They do have the Velcro option in the back but I don’t want to stick anything to my bike. They sit perfectly flat though so I foresee NO problems :) They are a quality material and hold everything I will need. I am very happy with my purchase!
