If you're like me and had issues in the past keeping warm on those cold nights when you're out camping, then this is the perfect solution. It provides instant warmth as soon as you turn it on. And like the Puffle, it's super versatile. It can be a normal heated bad, a back pack, foot heater, hand heater, stuff sack, you can put things inside to warm them up, put it in your sleeping bag to warm it up for you, and many more uses. I brought it with me on a weekend campout to Mt. Nebo State Park in Arkansas and I didn't bring any pants or a jacket because the weather prediction showed warm weather. When the temperature dropped into the 30s and 40s, the Hot Pocket (as well as my Puffle and other Sierra Madre products) kept me toasty and comfortable all night long. I would also highly suggest you get the free straps as they make it much more versatile.
