When I was first getting into lightweight backpacking, I spent an inordinate amount of time trying to create an ultralight protective case for my glasses to avoid crushing them at night.
I tried everything: from water and soft drink bottles, tupperware butter dishes, all kinds of small boxes, packing tubes, and so on. It was fun because I got to try using all kinds of everyday objects to accomplish the task. But I found it very difficult to break below the 3 oz barrier. This was better than most commercial hard cases which weigh a lot more, but it wasn’t really good enough for me.
Eventually, I gave up and just put my glasses in my boots or shoes at night, arranged near my head so I can find them at night if needed. This is sub-optimal because they pick up sweat from my shoes that makes them grimy the next day. It would be a lot better if I could keep them in my sleeping bag along with my headlamp.
But this morning, finally, I think I found a solution to this age-old problem.
I recently bought a new pair of Speedo Prescription Goggles for lap swimming. The goggle case was sitting next to my digital scale and I decided to weigh it. I almost fell off my chair. It was under 1 oz. and after a little creative trimming with my trusty office scissors, I was able to drop that to 0.7 oz / 20 g. I’m in heaven.
Since I’m wearing the glasses during the day, the case is not needed to protect my glasses in my backpack. I really only need it to protect them in my sleeping bag at night.
Now, if I could only make it smaller sized……
