Therm-a-Rest ProLite Mattress: An Affordable Ultra-light Self-Inflating Mattress

Therm-a-Rest ProLite Mattress on the ground

Whether you travel with an ultralight tent to camp in designated campsites or you plan to chill under the tree’s shadow, a mattress is a need to have. It’s an obvious assumption that outdoor surfaces are notorious of sharp pebbles and rocks that might hurt your back when lying down. As thus, one needs protective sleeping pads to prevent blisters caused by rocky surfaces. Therm-a-Rest has a ProLite Mattress in response to your desires.

Whenever participating in any outdoor activity such as hiking, particularly the long mileage ones, a light weight, comfort, and durability are paramount. The bottom-line is to have a minimal hiking or backpacking gear as possible to avoid hurting your back and straining your muscles.

Can you imagine a heavy weight of having a camping tent, a mattress, and other indispensable accessories? That could be too inconvenient. Fortunately, Therm-a-Rest ProLite Mattress brings a compact design that is portable enough to fit in many backpacks for your convenience. So, the weight issue is dealt and done with.

But then the ProLite Mattress is designed to keep you warm only in 3 seasons except winter. It is not that sophisticated with its insulation to an extent of overcoming the winter’s harsh outdoor temperatures despite having a warm tent. With this in mind, you will have to purchase an additional sleeping pad or a sleeping bag in order to survive, for example, the snowy surfaces because ProLite is only 1 inch high when fully inflated. It is nonetheless a great value for hikers that are fond of hiking in spring to the early fall when the temperatures are mild.

We have discussed the paramount features of this sleeping mattress below in order to give you a glimpse about its capabilities. These features can also be used as critical factors when evaluating similar products on the market prior to making a purchase.



The mattress will be shipped to your location in a 10 by 8 by 10 inch packaging, and it weighs 1.4 pounds. Since it is compact and lightweight, the mattress is sure to fit in your backpack easily, without stressing too much about space considerations or worrying that it will weigh you down when you decide to carry it during your hike.

Design and Durability

With a 50 denier Hex Rip Polyster, a ProLite sleeping mat reassures you durability of all the times. It can survive numerous uses in a variety of surfaces no matter how rough they are. Even if it gets punctured mistakenly, the pad can be patched with ease to keep its inflating features. This advantage is seldom seen in other sleeping mattresses due to their complex baffle designs. The urethane foam, the internal fabric, is also durable.

Weight is commonly an important feature that often trades durability when selecting sleeping mattresses. Many ultralight hikers focus on the weight to check if the product will not compromise their mobility whenever climbing steep mountains or travelling for hundreds of miles. But in most cases, with an ultraweight comes less durability and a compromised warmth in many sleeping pads. Just be vigilant about that.

ProLite sleeping mattress proves the convention somehow untrue for sleeping pads. It is lightweight yet durable and comfortable. The design and the brand have existed for many years, and, as many customers have asserted, durability has not been compromised in spite of the quest to trim excess pounds. The mattress weighs 1 pound and 5 ounces with dimensions 10 X 8 X 10 inches. This light weight can take you places. The pad can fit in your hiking gear, and can also fit in ultralight camping tents.

Unique Features

Some of the ProLite mattresses’ unique features are what sets it apart from others just like it on the market.

Comfort: Unlike its counterparts, the air construction sleeping pads, ProLite mattress offer a notably better comfort when camping on it. It has a flat surface and a self-inflating foam that plays a supporting role of providing comfort. What this means is that you can comfortably rest your body on this sleeping pad, either sleeping by side or against your back, without an adverse feeling of rocks or pebbles. Its self-inflating foam makes sure that it keeps the pad inflated at all times.

Furthermore, the Therm-a-Rest ProLite Sleeping Pad provides no bouncing sensation as is the case with other sleeping pads especially the air construction ones. Many campers have fallen in love with the ProLite’s firm and stable feeling. Moreover, the pad has a grip surface for a fixed position of sleeping.

Warmth: If you tell me about a sleeping mattress that fails to optimize warmth, I’d rather advise you sleep on the ground of your tent. Warmth is critical and paramount, especially when taking into consideration the cold midnights in the wilderness. All you need is a warm sleeping pad that has a high heat retention to avoid unnecessary convective heat loss.

ProLite comes with an R-value of 2.4, and temperature usage range of 28 to 30 degrees Fahrenheit. With these features, the mattress is sure to keep you cool and warm. But, a word of advice, do a thorough research about the temperature fluctuations of your desired hiking destinations and then act accordingly to pair the mattress with some blankets or sleeping bags for an added warmth.

Self-Inflating : Perhaps or arguably the most attractive feature in this sleeping mattress is its self-inflating feature. Imagine that moment you’re tired from a long distance hike, and then be faced with a non-self-inflating mattress to blow air into. That would be too much of a tedious work. ProLite mattress is self-inflating within the first 10 minutes of unfolding it from your backpack, although it doesn’t self-inflate to the maximum level. You only need a minimal blow to complete the inflation process. Then you’ll be all set up to sleep on your mattress.

It is also compressible in case you want to re-pack it and move to the next destination. But if you remain fixed at a designated campsite, we reckon you store it inflated to avoid the energy exhaustion of having to prepare it daily. ProLite sleeping mat scores high with this feature because majority of sleeping pads needs a tremendous blow to inflate them.

Pack size: With a diagonally-cut foam and a tapered shape, this sleeping mattress is compact and portable. The tapered shape eliminates unnecessary excess space at your legs. As thus, this makes it possible for the pad to be packed small. It comes with varying sizes, which include small, large, and regular.

Furthermore, the pad’s perforated foam construction trims the bulkiness that is seen in its predecessors. Its compressibility feature also plays a great role in its compact packable size. The stuff sack is provided to store the mat.

Versatility: It will be such a pleasure knowing that you can use your sleeping mattress in a wide range of applications or surfaces. Almost in every kind of hiking or backpacking, you can rely on ProLite mattress. Some of its uses include the following:

  • Laying it in an ultralight camping tent
  • Laying it directly on the ground on any surface when taking a rest during hiking
  • Laying it in your car to take a nap
  • Use it indoors in your household

And why not? It is lightweight, comfortable and warm. One thing to note about its warmth, though, is that during the extremely cold winter months, the mattress needs to be paired with other blankets and a sleeping bag to achieve optimal warmth.

On top of that, you have the durability of the mattress to consider as well.
