my husband and I have used IceMule coolers for 5 years. We dirt bike and now have a side by side, so we are out on the trail ALL DAY LONG. No time to go back to camp for a refill or more ice. No need when you have this amazing cooler. We pack 30 beers, ice & sandwiches in the 30L xl pack. I carry it in a North Face hiking back pack (for extra pockets to carry life saving items, and fishing gear!) we go out all day long, and always come home with ice still in the cooler, and this is in the summer. Hands down the best soft cooler on the market. It keeps our beer incredibly cold even in 100* weather. We started with the blue cooler and upgraded to the larger gray 30L and its way better. Softer yet sturdier, the top strap to close the cooler is way better because it's fabric. The other is welded plastic. And as much as we used it, that didn't last long but since it was in a back pack it didn't matter it didn't latch. But the new gray xl is by far the leader here. Bite the bullet and get the pro version from the start. Trust me you will not regret it. Happy trails!!The photos show me on the left carrying the IceMule Pro 30L XL in my back pack. The right photo is the Can-Am Maverick 1000r with the back pack in the trunk open.Buy this cooler, you won't regret it!!
