These sleds are rugged enough to be pulled over gravel or ice and snow. Different companies have them in different sizes, and they may be called by different names. They’re very light, weighing less than 10 pounds, and are made of high impact Polyethelene. For example, one company has a deer drag sled that’s 65″ long, 22″ wide and 5″ deep, weighing in at 4 lbs.
Another example is the Otter Sport Sled. I know of a couple of people who use sleds like these for moving pipes and wood and nursery pots for a greenhouse project. Or you could carry groceries from the car up a long driveway. Or, of course, you could actually use it for sledding if you like.
When out camping in the wilderness, you could perhaps tow a utility sled behind a canoe or kayak. It could be useful for transporting camping gear over snow while winter camping. How about moving valuables and supplies out of a flooded area?
So when carrying survival gear is a hassle, turn it into a real drag with a utility or sport sled like the Otter Sport Sled. Your back and knees will thank you.
