This isn't a Body Glide product review, but as an aside, this stuff rocks for foot lubricant, and for any other areas you are having blistering or chafing problems. Any way, back on topic -
Body Glide comes in 2.5oz, 1.3oz, and 0.45oz (not pictured) sizes. All of these are way more than I would use in a weeks time. When preparing for our recent trip to Mt Hood, I proudly packed mine in the above 0.25oz backpackinglight mini balm jar. After the 4 day trip was over it was still more than half full, and I had shared it with my wife the entire time. It was obvious to me that there was still weight savings to be had. Then the idea came to me...lip balm containers hold 0.15oz, still more than enough for a week!
The four containers above weigh 3.8oz, 2.3oz, 0.65oz, and 0.30oz full of product. Now you might think I'm splitting hairs going from the container that weighs 0.65oz to the one that weighs 0.30oz, but this is what ultralight is all about. If you do this with everything in your pack, it really shaves off weight quickly.
Think of it this way...the smallest container in the above example is a whopping 92% lighter than the largest option, and 54% lighter than the second lightest. So take everything you need, and nothing you don't. Sounds easy, but the concept is difficult for most people to grasp.
Simple, easy, and inexpensive...or in this case, free!
