Sleeping bags that zip together are a great option for couples who want to stay warm and cosy during their camping trips. They offer more space and flexibility, allowing one person to sit up or roll around without disturbing the other. Additionally, they provide the comfort of sleeping next to your partner and create a bed-like experience. When choosing zip-together sleeping bags, it is important to consider bags with opposite side zippers, such as men's and women's bags from the same manufacturer, to ensure compatibility. Some popular options include NEMO, Macpac, Marmot, and Haglöfs, which offer various features and temperature ratings to suit different needs and preferences.

What You'll Learn

Warmer than single-person sleeping bags
Double sleeping bags can be warmer than single-person sleeping bags, but there are a few factors to consider. Firstly, it's important to ensure that the two individual sleeping bags are compatible and can be zipped together securely. Some bags are designed with specific zippers that only work with the same model, so it's worth checking before purchasing.
When zipped together, two sleeping bags can create a much warmer space than a single bag. This is because the body warmth of two people combines to increase the overall temperature inside the bag. Additionally, the extra space provided by connecting two bags means that individuals can move around without disturbing the other person, reducing the risk of cold spots.
However, it's important to consider the potential heat loss associated with zipping two bags together. The void area above the zipper, near the hoods, can be a problem, and the zippers themselves can create gaps in insulation. To minimise heat loss, ensure that the zippers are fully closed and consider using a sleeping bag liner or a down quilt for extra warmth.
Another option for couples is to use a one-piece double sleeping bag, which doesn't have zippers and thus provides more even insulation. However, these bags might not be as convenient as two bags that can be separated, especially if one person sleeps warmer than the other and prefers to have more ventilation. Ultimately, the decision between a double bag and two individual bags depends on factors such as temperature ratings, weight distribution, and personal preferences for comfort and intimacy.
To enhance the warmth of any sleeping bag setup, consider using a fleece liner, which can add significant warmth without much additional weight. Additionally, ensure that your sleeping bag is rated for the temperatures you expect to encounter, especially if venturing into extremely cold environments.

More room to move around
If you're looking for more room to move around in a zip-up sleeping bag, there are a few things to consider. Firstly, not all sleeping bags are created equal when it comes to zipping them together. Some bags have zippers that are not compatible with those of other brands or even other models from the same brand. So, before planning to zip up your sleeping bags, make sure to check the zipper compatibility.
Once you've confirmed that your sleeping bags can indeed be zipped together, it's time to get them ready. You'll need one sleeping bag with a left-hand zip and another with a right-hand zip. It's also important to ensure that the zips are the same size and that the sleeping bags are the same model, as this will make the process much easier.
Now, onto creating that spacious sleeping setup! Line up the two sleeping bags next to each other, with the men's sleeping bag on the left and the women's bag on the right. This arrangement ensures that the zippers will match up correctly. Start by connecting the back zipper tracks of the two bags, just as you would with a jacket zipper. Make sure the zipper pull is fully open and touching the zipper stop at the end. Then, slide the non-pull side into the two zipper pulls, ensuring that both pulls are together at the end of the track.
With the bags successfully zipped together, you'll notice a significant increase in space compared to a single sleeping bag. This extra room provides ample space for one person to sit up and reach for something while the other person sleeps soundly. It also allows for more independent temperature control, as one person can choose to unzip their side of the sleeping bag without disturbing their partner.
Additionally, the larger space means you can roll around without the sleeping bag moving with you, providing a more comfortable and less restrictive sleep. This extra room also comes in handy during warmer nights, allowing you to sleep apart without constantly brushing shoulders.
In conclusion, by choosing compatible sleeping bags and following the zipper instructions, couples can enjoy a more spacious and comfortable sleeping arrangement. This setup offers the benefits of increased personal space, easier movement, and the ability to regulate temperature independently, all while still enjoying the coziness and closeness of sharing a sleeping bag.

Easier to store
Zipping two individual sleeping bags together can make them easier to store. When zipped together, the sleeping bags can be treated as one unit, which can be more convenient and space-efficient than storing two separate bags. This is especially true if you are using a stuff sack or compression sack for storage. By joining the two bags, you only need one sack to contain them, reducing the amount of storage space required. Additionally, having one larger bag created by zipping two bags together can be more manageable than dealing with two separate bags, making it simpler to roll or fold the bag and secure it for storage.
It is important to note that not all sleeping bags are designed to be zipped together. Before assuming that zipping your sleeping bags will make them easier to store, check that your bags have compatible zippers. Bags from the same manufacturer and model are more likely to be compatible. Some manufacturers, like NEMO, design their sleeping bags to be zipped together, ensuring seamless connectivity. However, bags from different manufacturers may have zippers of different types, sizes, and configurations, making them incompatible.
Even if your sleeping bags can be zipped together, there may be instances where storing them separately is more advantageous. For example, if you are backpacking or hiking and need to divide the gear equally among group members, it might be more convenient to keep the bags separate so that they can be distributed individually. Additionally, joined sleeping bags may be bulkier and heavier, impacting storage options, especially in limited-space scenarios like backpacking trips.
To optimise storage when zipping two sleeping bags together, consider using a larger stuff sack or compression sack that can accommodate the combined size of the bags. Ensure that the sack is made of a lightweight and durable material to minimise added weight and maximise protection. It is also beneficial to look for sacks with compression straps or features that allow you to reduce the volume of the sleeping bags, saving space. Finally, practice good rolling or folding techniques to minimise the overall bulk of the joined bags, making them more manageable for storage.
In conclusion, zipping two sleeping bags together can offer storage advantages by treating them as a single unit, reducing the number of storage sacks required, and potentially simplifying the process of storing them. However, it is essential to consider the compatibility of your sleeping bags' zippers and the specific storage constraints of your outdoor adventures to determine if zipping them together truly enhances storage efficiency.

More comfortable
Zipping two sleeping bags together can be a great way to create a warm and comfortable sleep environment for two people. Here are some tips to ensure a more comfortable experience:
Firstly, ensure that your sleeping bags are compatible for zipping together. Not all sleeping bags can be zipped together, so check that the zippers are the same size and have the same teeth orientation. Some brands, like NEMO, design their sleeping bags to be compatible, offering men's and women's models that can be zipped together. If you are using sleeping bags from different brands, make sure the zippers align correctly before attempting to force them together, as this can cause damage.
Secondly, consider the temperature ratings and your individual sleeping preferences. If one person tends to sleep warmer than the other, you may need to adjust clothing or have the option to unzip the top portion of the bag for added comfort. Keep in mind that double sleeping bags can be draftier due to increased air circulation, so the extra body heat from your partner will be beneficial on cold nights.
Additionally, pay attention to the sleeping bag features that enhance comfort. Look for bags with hoods that can be adjusted with drawstrings to keep your heads warm. Also, ensure that the sleeping bags have enough room to allow one person to sit up and move around without disturbing the other person's sleep.
When zipping the sleeping bags together, follow these steps for a secure connection: separate the zipper tracks by moving the zipper slider to the bottom of the bag and pulling the track end out of the slider. Line up the two bags with the men's bag on the left and the women's bag on the right (if applicable). Match the back zipper tracks first, followed by the top zipper tracks, ensuring the zipper pulls are fully opened and touching the zipper stop. Finally, slide the non-pull side into the two zipper pulls, making sure both pulls are together at the end of the track.
By following these tips and choosing compatible sleeping bags, couples can enjoy a warm and comfortable night's rest while camping or outdoors.
