Optimal Tent Floor Thickness

In addition to providing a lesson on how tent floor thicknesses are measured, this Outside online reader response offers a great idea on how to avoid the weight question altogether for ultra-light tent floors: “Myself, I wouldn’t agonize too much over it. What really helps is to get a roll of 4mm clear plastic at the hardware store. Cut yourself a piece that is slight smaller than the footprint of the tent, and then pitch the tent atop that. That saves a ton of wear as you grind the tent into the dirt while sleeping. And there is a very small weigh penalty.”
