Whether I’m hiking or commuting to the office, this sturdy plastic sheath never fails. The two ends connect in the middle, where a slight turn locks the unit in place. Even when the bunker winds up at the bottom of my bag, the two pieces stay united. The straw-like section gives only slightly, so curvier bananas are harder to fit; really long bananas are a tight squeeze, too. However, in time, you learn to spot bundles in the market that will fit just right. I use my bunker no less than three times a week. Based on all the smooshed bananas I used to toss out, this contraption has already paid for itself dozens of times over.
