"It may seem off to see something like a \"sleep system\" in a gear review. After all, what is that? Shouldn't it just be bed rolls and/or tents and/or bivouac reviews? Well yes and no. As we will get into, the Zenbivy is much more than just a sleeping bag, or just a mattress. It's, in my opinion, a sleep system."
