Review

Design and Durability

This quilt is ideal for backpackers, campers, hikers, and other outdoor enthusiasts who see the need to get a rest during their multi-day night-out. Corus HD Quilt serves as an alternative to those heavy weight blankets or sleeping bags that are worth many pounds.

This sleeping system is suitable for ultralight hikers who are fond of ultralight products that still offer a great warmth more than or similar what heavy weight do. With an overall weight of 1 pound and 6 ounces, the Corus HD quilt is sure to lighten your hiking gear in any distance range you intend to travel.

This is a portable weight for such an indispensable outdoor sleeping system because plenty of sleeping bags seldom have that kind of lightweight. So Corus HD quilt is one of a few with this impressive ultralight performance. It can be fitted in your hiking gear so that you can hit the road without the fear of straining your muscles with an overweight gear.

Size

The product is available in regular and long size, which then qualifies it to be used by many people without size inconveniences. Moreover, it can attach other sleeping accessories such as the Therm-a-Rest NeoAir XLite Sleeping Pad and/or the Therm-a-Rest Universal Sheet for an added warmth.

So you have a choice to use this ultralight sleeping bag on its own or to combine with these mentioned accessories to be bought separately. With these being noted, there’s probably no an excuse that the sleeping bag will not be suitable for you because of the typical temperatures in your preferred destination.

Warmth

However, the ultralight performance of this product has its downside for the year-round hikers. The winter warmth provision is traded off with the light weight. This implies that you might not find it worthy to use it in winter because it may not shield you against the harsh temperatures in the wilderness.

This is in spite of the insulation and the ThermaCapture feature that this sleeping bag has. Besides, due to the scarcity of sunlight in winter times, you will hardly find the ThermaCapture useful because no enough radiant energy to retain.

But if you are fond of hiking or backpacking in the summer or fall season, this is the ideal solution for you with the temperature comfort range of 35 to 45 degrees Fahrenheit.

Weight

Ultralight hikers often prioritize the weight of products in a quest to have an ultralight gear. As hikers or backpackers, you might have a lot in your gear such as the food, utensils, tents, clothes, and stoves.

All these already accounts for a massive weight to your body and that’s bad. Luckily, the Corus HD Quilt is lightweight, with just 1.6 pounds that is compact enough to fit in your gear. This light weight is the struggle yet to be won by other outdoor accessories without compromising warmth.

So, because we know you’re into lightweight sleeping bags, Corus HD has come to your rescue. It’s an important feature not to be overlooked.

Comfort

This is undeniably one of the foremost features that hikers prioritize when coming to sleeping bags. To start with, why would you opt for an outdoor bedding that could make your nights worthless to cherish? Pointless, isn’t? Of course the comfort of the bedding supersedes many features such as weight.

And this comfort may be seen in the warmth of this sleeping bag and its proper fit when sleeping in it. The comfort of Corus HD extends to its insulated and elasticized footbox to keep your feet warm.

So whether you are sleeping in damp conditions or mild winds, this sleeping mat will be warming up your feet. The footbox also helps in keeping the quilt in place to prevent it from slipping through while sleeping.

Versatility of the Quilt

The Corus HD Quilt is one of the most versatile outdoor sleeping system. For instance, if you want to use it in the late fall or winter amid the cold temperatures, you can easily pair it with additional warmth accessories such as the mattresses and other sleeping bags. Its perimeter snap loops make this the most versatile.

This means you do not have to resort to other options when the temperature has badly disappointed you. These aforementioned features are certainly the most important features for the Corus HD Quilt from Therm-a-Rest company.

The company has invested in this product to bring an innovative ultralight sleeping system that features, predominantly, the 650 fill Nikwax Hydrophobic Down and the ThermaCapture technology. All these features synergistically up the comfort level of this quilt. Now that you know about the features, let’s delve into the review.

Value for the money and Guarantee

The price of the Corus HD sleeping system ranges from $180 to $250. It varies from one supplier to another. Well, you can expect to pay more if you consider the Therm-a-Rest sleeping pad and the sheet, which costs between $110 to $400 and $25 to $80, respectively.

The frequent outdoor explorers will agree that this is in fact a good investment. It may look as if it’s a bad investment if outdoor sleep-out isn’t your thing. Otherwise, you can just hire the guest houses.

Special Features

The Corus HD Quilt sleeping bag is characterized by plenty of features that are akin to surviving a night-out in the wilderness. Among others, the most paramount features of this product include its ultra light performance, comfort, weight, retention of radiant energy through ThermaCapture, compartmental storage sack, and an insulated footbox.

These are the features that play an integral role in this product’s capability to be your best mate when camping in the wilderness.

Retention of radiant energy

As light as it is, it might raise concerns to other campers that how will they get warm in the cold nights. Well the Corus HD sleeping bag has an integrated patent pending ThermaCapture technology that helps maximize the temperature regulation and also retain heat energy.

During the day, the technology will be able to absorb radiant energy for use in the absence of the sun. This is done to ensure that you stay warm and survive the cold nights, thus negating the need for extra blankets which could lead to added pounds on your gear.

As a result of ThermaCapture integration, Corus HD offers an excellent warmth per gram compared to its predecessors and other competitors. Now you can conveniently enjoy your nights with an added warmth provided by the ThermaCapture as well as the insulated seams.

Warmth of the sleeping bag

As already emphasized above, the Corus HD derives its warmth from ThermaCapture and the insulated seams. Also notable is its full-perimeter side baffles that play a huge role in providing warmth for the wearer. It’s a great warmth package that is necessary for mild temperatures of the spring through to the early fall.

Unfortunately, we cannot say the same with winter temperatures because the product’s insulation has not been designed to survive the winter’s inclement temperatures. Such inclement temperatures can be supplemented by the pad attachment systems wherein the Therm-a-rest sleeping pad can be integrated.

Moreover, the sleeping bag’s perimeter snap loops make it possible to attach the Therm-a-Rest mattresses or another sleeping bag or blankets for added warmth in case you are not satisfied to use it alone. This could probably be applicable should the weather be unpredictably and unexpectedly harsh.

Compartmental storage sack

For your storage needs, Corus HD quilt provides you with the storage sack and the external snap pocket. You can imagine safeguarding your valuables such as the smartphones or jewelries while sleeping. The choice is yours.

This storage sack makes the quilt more user-friendly. Additionally, the footbox is yet another feature to be embraced as it serves as the storage of your feet, while at the same time keeping them warm.
