4 Important Performance Factors of Therm-a-Rest Sleeping Pads

Therm-a-rest Sleeping Pad Performance Factors.001

Before heading out on you next camping adventure, it’s important to always remember to pack the essentials.

For a majority of trips, packing and bringing a sleeping pad is critical. A rock-solid camping sleeping pad really make the difference between having a good, restful night and an unbearable, terrible night.

So, when it comes down to which sleeping pad has the best performance for your needs, it really boils down to 4 important performance factors – (1) comfort, (2) insulation, (3) size, and (4) durability.

1. Comfort

A camping sleeping pad is primarily designed to keep you up off the ground. Whether you’re camping in a grassy field, or a rocky mountain side, a sleeping pad can provide some much needed cushion between your body and the tent floor.

This provides your body the support it needs to rest and sleep comfortably. And, to maximize comfort, sleeping pads usually offer a thick and wide surface to support your upper body.

The trick is to find a sleeping pad that has the optimal thickness and size!

If it starts getting too large and too thick for your body, then it’s probably unnecessary. The added weight and larger dimensions, which would take up more space in your pack, isn’t efficient.

Well, the Therm-a-Rest Pro-lite Plus is optimally designed with comfort in mind:

  • When inflated, the sleeping pad is xx mm (2 inches) thick
  • It’s xx mm (77 inches) long and xx mm (30 inches) wide
  • The bottom has a non-slip coating to prevent movement on a tent floor

2. Insulation (R-Value)

In addition to comfort, a sleeping pad also helps to insulate your body from the ground.

This can be especially important while camping during cooler months – your body can loose a lot of heat through the ground.

So, it makes sense to sleeping on a pad that can resist and prevent excessive heat loss.

The insulating performance of a sleeping pad is measured by its “R-value”. The greater the R-value, the greater the insulating capacity. R-values range from 1 to 5 and above. [R-value explained]

3. Size (and Weight)

Camping sleeping pads come in a variety of shapes. 

  • Mummy-shaped pads provide maximum support for your upper body, then gradually taper to your legs which require less support
  • Square-shaped pads are more traditional and provide the greatest amount of surface area to support your entire body

When selecting the right sleeping pad for your body, it’s important that you know your height and shoulder width. You can then match up these dimensions with available sleeping pads.

However, to save a little bit of weight for warm weather camping, you can choose a sleeping pad with a slightly shorter length than your body. That’s because your feet don’t necessarily need to be fully supported or insulated.

And, depending on its size and type, sleeping pad weights can vary greatly:

  • Typically, single person air sleeping pads are the lightest, followed by foam, and finally self-inflating.

4. Durability & Quality

An often overlooked aspect of camping gear is the overall build quality. And, if you’re like me, you want the best gear that will last a lifetime.

Well, Therm-a-Rest utilizes high performance materials such as ripstop nylon, polyester and polyurethane because those materials result in the following:

  • High strength and lightweight fabric
  • Wear resistant and durable surface
  • Protection against water and moisture

Therm-a-Rest also offers a 2-year limited lifetime warranty on all their products. This is a testament to their commitment to product quality and guaranteed performance.

How to Properly Use (Inflate, Deflate & Pack) a Therm-a-Rest Sleeping Pad

Generally, camping gear that is complicated or difficult to use is just going to sit in a closet or in a garage unused forever.

But, using a Therm-a-Rest sleeping pad is dead simple. That’s because it’s been designed with the camper in mind.

So, whether you’re getting ready for bed with your family, or resting after summiting a mountain, using a Therm-a-Rest sleeping pad correctly is straight-forward.

To properly inflate a sleeping pad, follow these steps:

  • Unravel the sleeping pad
  • Open the air valve
  • If the sleeping pad is self-inflating, let the foam inside rise and partially inflate the pad
  • Using your mouth, blow air into the valve by taking deep, sustained breaths
  • Keep adding air until the sleeping pad is sufficiently blown-up
  • Close the valve to lock in the air pressure

Depending on the outside air temperature, the internal pressure and firmness of the sleeping pad might change. Warmer days and cooler nights might cause the firmness to drop.

So, just monitor the firmness before sleeping and add more air as required.

Deflation & Packing

To properly deflate and pack a sleeping pad, follow these steps:

  • Open the air valve to start releasing air
  • Start rolling the non valve end of the sleeping pad
  • Close the air valve
  • For self-inflating sleeping pads, fold the pad in half (long-wise), and re-roll the sleeping pad from the non valve end
  • Use your knees to compress the sleeping pad as you roll
  • Once rolled to the valve end, keep knees on pad and open valve to release remaining air
  • Close air valve and place sleeping pad in carrying case, if required

Valve Improvements

Sleeping pad air valves have improved over the past few years. Before, you had to skillfully manage the open and closed position of the valve while inflating to prevent air loss.

Now, Therm-a-Rest sleeping pads come with an improved dual-acting “WingLock™” valve for easier filling and deflating, even while wearing gloves.

For inflating, the valve allows for one-way air flow, so there’s no risk of losing air when blowing.

For deflating, the valve can be fully opened to release the air through a larger opening, speeding up the entire process.

After 10 years of continuous use, I can unequivocally say that the Therm-a-Rest Pro-lite Plus sleeping pad is incredibly comfortable and worth every penny.

Recently, I found that my sleeping pad can provide an air cushion for my hammock. This helps better support my body, and it provides better insulation from the outside cold air if I were to sleep in my hammock.

Chair Conversion

I also purchased a Therm-a-Rest chair conversion kit that turns my sleeping pad into a super comfortable chair I can use anywhere. It’s great because I don’t have to carry a dedicated chair for backcountry and backpacking trips.

The chair kit is incredibly useful, not only for camping. I bring it along on picnics in the park, to outdoor festivals, and open air concerts. It allows me to sit comfortable for extended hours, and not have to worry about straining my back!

Make-Shift Board Game Surface
