They call these things rest sacks for a reason. The reason being that they’re good for napping in and if you wanted to, you could theoretically do so. This holds true for even this PVC inflatable rest sack. Though it may look a bit breathtaking to the untrained eye, it is actually extremely cozy and comfortable and super breathable. These two fellows find this out for themselves when they take turns being put into the rest sack by Hinako, who sets them up real nice with a Hitachi and bit of alone time.
