Guys (and Gals),

I recently decided to get rid of the large Kolpin fuel pack and water pack to get something smaller.
After trying to figure out how to downsize, I took a look at rotopax again.
They recently came out with these new 1 gallon packs.
After looking around, I gave them a call and talked to Jason.
I learned a few new things.

Rotopax are made different. They are "roto" molded instead of blow molded like the kolpin. (The new Kolpin packs, not the old ones made by the rotopax guys in the past) This means the mold is spun to ensure that the plastic gets around and coats everywhere to keep from having weak spots.

Most people have not owned the new kolpin packs AND the rotopax. If you want to know what the difference is.. take an empty kolpin pack and an empty rotopaxpack and squeeze them. The rotopax feels like it is AT LEAST twice the thickness. No joke. My one gallon feels bullet proof. When I pulled it out of the box I could tell that this thing could double as a skid plate. The kolpin feels like a thicker 2 liter bottle in comparison.

The pack mount I received with the pack is really solid. They look nice in the picture, but until you feel the weight and sturdiness of the mount, it's hard to describe. I was a little skeptical about it being able to take some punishment, but not anymore.

The rotopax is hands down superior to the Kolpin. Please.. fellas.. don't throw any money away on Kolpin anymore. The rotopax is the real deal. I am only ranting and raving about this because I feel like I threw my money away on the kolpin stuff, and I don't want you guys to do the same.

I never had a problem with MY kolpin packs.. other than the water one leaking. (this was before I had the gas one)
I called Kolpin and they sent me the carb nozzles that don't leak. Sweet. I was ok in that dept. My friend bought a kolpin gas pack as well. He got a call from his apartment lease office about a gas smell coming from his garage. The kolpin pack was EMPTY. All of the gas had slowly seeped out. There was a small pin hole in the bottom corner of the pack. Not on the seam.. the corner. AND NO DAMAGE.. JUST REALLY THIN PLASTIC!! Anyway, just wanted to let everyone know that I didn't switch over because the kolpin is a bad pack. But after getting the rotopax, I know that it is by far and beyond a better product. It is like comparing the Grizzly to one of those side of the road pocket rocket bikes. One is great, and one is a scaled down novelty.
