Anytime we venture into the backcountry, efficiency becomes a major issue. How well is your backpack packed? Did you bring unnecessary gear or clothing? Are you prepared to deal with unpredictable weather or other situations? Is your camping sleep system able to meeting your changing needs?
Layering Is The Solution
These questions of efficiency also arise while we are designing gear and planning our product offerings. Over the years, we’ve tweaked and tested our products and found that one of the easiest ways to get a more versatile and efficient sleep system is by layering.
Let’s say you have a summer-weight sleeping like the Space Cowboy 45F/-7C. Now, let’s say you have a big trip coming up and the lows are going to be dipping below freezing. You can’t use your rugged and lightweight Space Cowboy on your trip, right? Well, you could if it was layered with your Corus 35F/7C.
We spent some time testing different Therm-a-Rest sleep systems at Kansas State University and in our on-site cold chamber. Using the data from those tests, we were able to assign official EN/ISO temperature ratings to many of these systems and predict the relative comfort in different conditions. These precise measurements help us make more informed decisions on how to build more efficient sleep systems and help you decide what to gear you need to bring to stay comfortable at camp.
Building a Camping Sleep System to Fit Your Needs
So, with a Space Cowboy and Corus in your gear closet, you could comfortably sleep in temps ranging from 20 to 50 degrees by using the products together or on their own. Add a Parsec 20F/-6C to the mix and you could sleep in conditions as cold as 5 degrees.
Check out the table below to see the effects of combining a few of our favorite Therm-a-Rest pieces.
Versatile and efficient gear is never an accident. By carefully combining different sleeping bags, quilts, pads, and blankets, you’ll soon have a layered system that perfectly suits the needs any adventure.
