Often overlooked, a hammock sleeping pad is considered one of the most important items of camping gear to ensure warmth and comfort during the night.
In this article we take a deep look into what makes these pads such a useful and versatile companion when hammock camping, and discuss what exactly we need to look out for before purchasing one.
Do you need a sleeping pad with a hammock?
For most people, sleeping in a hammock is an extremely comfortable experience, however during the evening and night when temperatures drop, there is little to no insulation to protect you and sleeping bag from the cold air coming up from the ground; and this is where a sleeping pad comes in.
Often compared to underquilts, a sleeping pad sits between you and the top of your hammock. Some users however prefer to place the pad inside their sleeping bag, as this can also stop it from moving around and add stability to the entire sleeping setup.
When comparing a sleeping pad to an underquilt, a sleeping pad is much more versatile than an underquilt as it can also be used on the ground. But most importantly, it is the air-space inside the sleeping pad that provides the much-needed nighttime insulation. An underquilt does not have this.
With the right approach, a sleeping pad can be both comfortable and insulating, providing extra warmth during both the night and day.
Advantages of using a sleeping pad
Hammock sleeping pads are made for thermal protection. Their main role is to trap air between the cold hammock and the user. Here’s what users say the benefits of a sleeping pad are.
- An extra layer of insulation against cold air.
- Improved comfort with extra cushioning.
- Helps maintain body temperature.
- Keeps the user dry.
Types of sleeping pads
Closed-cell foam pads, inflatable pads, and self-inflating pads are the 3 types of sleeping pads that are predominantly used today. Neither one of them is truly superior to the other however, as each has its own merits and uses.
Closed-cell foam pads
Closed-cell foam pads or simply foam pads are made from foam, as their name suggests. There’s no air that can come out of these sleeping pads which makes them highly durable, and risk adverse to punctures.
Typically smaller, these foam pads are also practical as many of them fold and role up to be attached to the underside of a backpack.
While they come in different thicknesses, the main drawback of a closed-cell foam pad is that they lack cushioning or proper support. In a hammock, this might not be as big of a problem. But if used on the ground for a quick nap it won’t offer sufficient cushioning from small rocks and rough ground.
Inflatable pads are hard to match for comfort, since they tend to be the thickest, and therefore provide the most cushioning. When fully deflated, they’re also the smallest as there’s only thin nylon left without the air, which helps with storage space.
A disadvantage of using this type of pad however, is that under the user’s weight the air can get displaced, and both thermal insulation and comfort can suffer.
This is what led some manufacturers into creating additional support to minimize air displacement. Inflatable pads can also be prone to puncture and/or losing air during the night, especially in cold weather when its materials contract.
Self-inflating pads pride themselves for not requiring user input. They come with an air valve, normally in one of the 4 corners, that allows air in and out with quick clockwise and counterclockwise movement.
However, most self-inflating pads are not truly independent as they do often require several breaths from the user to get them started.
How to choose the best sleeping pad for your hammock
When it comes to choosing the best sleeping pad, it’s all about the details. Not all of them are made the same, and those new to the outdoor world should learn how to assess them via their most common characteristics.
The amount of insulation a sleeping pad provides can be quantified under its R-value. This rating system is used to guide users on the thermal level of a sleeping pad. The higher the R-value, the more thermal protection provided.
The R-value can also be tied to seasons and their changing temperatures. During the warm months of summer nights, users can rest on sleeping pads with an R-value of 2 or 3. As the temperature begins to drop, outdoor enthusiasts need to choose a higher R-value rating of 4, especially in conditions close to freezing temperatures.
A sleeping pad improves thermal insulation. But many still use them with a sleeping bag. When it comes to pure warmth, underquilts are superior as they come with the wrap-around design. But as seen above, sleeping pads use thin nylon materials which generally allows them to be lightweight.
The R-value of the sleeping pad is the value used to determine warmth. In general, it’s difficult to rely on R-value alone to establish thermal protection as they’re mainly used with sleeping bags. But they can be categorized as follows
- Warm weather – R-value of 2
- Cool-weather – R-value ranging from 2 to 4
- Cool-weather – R-value ranging from 4 to 5.5
- Freezing temperatures – R-value of 5 and above
D-value or denier-value is used to measure the durability of materials such as nylon. Manufacturers often advertise sleeping pods made out of 40D or 20D nylon.
This refers to the D-value of the material. The lower the D value is, the lighter the nylon is. However, low D-value nylon is less durable. High D-value of 50D and above nylons are thicker and heavier. But they’re also superior in terms of durability.
The cover of the sleeping pad is often made out of nylon or polyester. The material is lightweight and affordable, which makes it a popular solution for hiking and camping. Within the sleeping pad itself, the air is what determines the price of the sleeping pad further.
Air sleeping pads are the most expensive and the most popular. Some sleeping pads are filled with synthetic materials and they require no air at all. These can be slightly harder to come by, but feature materials such as memory foam for thermal insulation.
Pads vs underquilts
The pad vs underquilt debate is highly subjective and a matter of personal preference. While many users find an underquilt to be more comfortable, there are instances where the sleeping pad performs better. For example, those who also like to sleep on the ground will find sleeping pads far more versatile.
In some instances there is also an issue of user size. A few outdoor fans note most sleeping pads are limited to 20” width, which is not enough to insulate the shoulders.
Depending on the manufacturer, there are various sleeping pad shapes. Those who’ve slept on a straight sleeping pad know they can slide easily. This is where the V-shaped sleeping pad comes in handy as is prevents this.
Air sleeping pads come with a fixed shape. Some closed-cell sleeping pads, as well as foam sleeping pads, can be cut to a very specific shape, which may help to shorten the sleeping pad or making it narrower to fit the hammock better.
Packing and storing
Low bulk materials such as nylon can be popular when it comes to packing and storing as they save space. Once deflated, they can measure only 9in X 3.5in and can easily be attached to a backpack. The weight of the sleeping pad can also vary between 8oz and 15oz for most popular products available today.
Sleeping pad noise is a real issue for comfortable sleeping. The scratchy nylon noise is something that can’t really be minimized, especially in contact with a sleeping bag. Nylon and polyurethane materials are noisy regardless of the type of sleeping pad and its thickness.
Air pads vs foam pads
Air pads and foam pads are different. Due to the materials, foam pads are more expensive but they can also represent a more versatile option. Here are the mains strengths of the sleeping pads.
- Inflatable sleeping pads are more comfortable
The extra air in the sleeping pad allows proper cushioning. This can’t be achieved with most foam pads with a foldable profile. Today, inflatable air pads are also made with multiple seams and structural support to keep the air from moving around and offer support in the right and key areas.
- Lightweight and reliable in warm weather
Air pads are very lightweight. Their thin materials are a good option for those hiking with heavy gear, or for anyone who prefers to travel light.
- Foam pads prevent punctures
On the other hand, foam pads have their advantages. Preventing punctures is often stated as their biggest asset, which makes them more durable. From this perspective, they can be useful for frequent users.
- High R-value
Due to the nature of the materials, foam pads have a higher R-value rating. Users who prefer to use a hammock outside the warm summer months might need to also choose a foam pad for extra thermal comfort.
- Multiple uses
Foam pads now come in foldable designs which means they can be used on the ground as well, without the risk of punctures. Once folded, they can be used as sitting surfaces replacing chairs.
