Big Agnes Flying Diamond 8 vs. Rei Kingdom 8


A good camping tent really matters when it comes to vacationing outdoors. No one would want to be poured on in the dead of the night, while you run around for refuge to the nearby trees, especially if you have got a few members of family with you. Camping under the open sky is fun only if you are protected from the bad weather and wild animals and insects.

Camping is a fun and enjoyable activity, which deepens the bond with your family or friends. So, you should try to make it as pleasant and relaxing as possible. Of course, there is only so much you can control while you are out there on your own, but you can still take some measures that will ensure you a pleasant experience. For example, you can select the tents made of high-quality material. Only go for waterproof and windproof tents that are known for their reliability.

If you are not sure that you can choose a good tent on your own then we are here to help. In this article, we have compared two popular camping tents that are suitable for 8 people. That is what the 8 stands for in their names.


The market for camping tents is huge. If you start looking for it, you will come across hundreds and thousands of products. While it means that there would be a lot of variety it also means that it would be confusing to select the final product. That is why we have selected a few features that are important in every camping tent and reviewed our products keeping those in mind. Those features are as follows:

  • Tent Setup
  • Waterproof and windproof
  • Ventilation
  • Durability
  • Space
  • Affordability

Now we are going discuss all of these features in detail and find out why they are important and why you should make your decision based on them.

Tent Setup

When it comes to big tents, what you should first think about is the setup. To put it simply, it should be easy to setup. If it takes you more than 30 minutes then you should probably think about buying a tent that is easy to setup. You may think that 30 minutes is not that long, but don’t be so hasty in making that assumption. When you are tired from the day long walking and hiking even 10 minutes will feel long to you.

Also, you can never be sure when it rains. If you can’t easily set your tent up, you along with your family will get wet and cold. Every tent should be easy to setup and it shouldn’t require more than 3 people to complete the process. Some manufacturers make setting up easy by making color coded and reflective poles and guylines that glow in the dark. This makes sure that you can setup your tent even if it gets dark.

Waterproof and Windproof

If you are going to spend a night out in the wild, you need a tent that is waterproof. So that while you are not harshly pulled out by the cold rain from the dreamland in middle of the night. We don’t even need to tell you how important it is for your tent to be waterproof.

Always go for tents that have sealed seams. Sealed seams are not only necessary in the rainfly and the canopy, but also the floor. Guess where the rains goes when it pours down the rainfly. You are right, it goes down to the earth where your tent rests.

So, if your tent floor is not made with right material and is not properly sealed even if you are protected from above the water will sweep in from below in to the floor where you are lying.

Also, it is necessary for the tent to be able to weather bit of the strong wind. Buy tents that have strong poles made of aluminum or another strong alloy. They shouldn’t bend or break easily. 


As important as it is for your tent to be weatherproof, it is also essential for it be breathable. That is only possible if the tent has rainflies, windows and more than one door. Rainflies are important even in the damp weather. They ensure that condensation doesn’t happen. Condensation can make a dry tent wet.

Windows and doors with mesh cover let in fresh air in without allowing mosquitos and other insects. This way you can rest in the comfort of your tent enjoying the fresh air. Most tents have a mesh cover and some other fabric as a canopy, which is covered by the waterproof rainfly. Those tents are even more breathable. 


When you are out in the open with your children and other family members, you solely rely on your tent for cover. It is your temporary home. So, of course it should be durable enough to last for a few trips. If your tent is made with good quality materials then there is a good chance that it will last for while if you take care of it and store it properly. The more water resistant and windproof it is the more durable your tent will be. Because that means the manufacturer paid extra attention to the quality of the material.


If you are reading this review then that means that you are interested in buying a big tent. You must be looking for space in the tent. The bigger the floor space of the tent the better. You can place your essentials and bags in one side and use the rest for sitting and sleeping.

Most of the big tents offer the feature of vestibules. Vestibules are a good addition in your tent. You can get imaginative and use this extra little space for so many things. You can place your wet boots, coats or socks in there to dry. You can cook here or watch the drizzle from nearby while you sip on your coffee or tea. You can even set it up to make shade in the warm days. Or if you think that inside the tent is cramped you can even place your luggage in the vestibule and make room inside.


No matter how great a product is if it is out of your reach money-wise then it is no good of a use to you. There should be a good balance between the product’s quality, features and its price.

1.  Can I fit maximum number of people in my tent?

The maximum number of people that the manufacturer says can fit in their tent is mainly for advertisement purposes. If you put your sleeping bags, mats and bags inside the tent there is a good chance that you won’t be able to cram the maximum number of people that the manufacturer suggests.

2.  Can I use the tent stakes that come with my tent?

If your tent stakes are made with plastic or even aluminum they will break or bend easily in the face of strong winds. They might even break if you hammer them in the ground. So, you’d be less frustrated if you buy some sturdy stakes that can take the abuse of hammering and the force of strong winds.

3.  Are the Big Agnes 8 and Rei Kingdom 8 suitable for hiking?

No, they are family size tents. They are big and very heavy. You will not be able to hike with them. The best thing that you can do is carry it around in the trunk of your car.

If you are out camping and it starts snowing then, yes, you can use them. But you should avoid using them in the snow. They are mostly 3-season tents and not suitable for very cold weather.

5.  How do I make my tent waterproof?

Both of the tent that we mentioned here are reliably waterproof. But just for the sake of this question there are a few things that you can do to make your tent waterproof.

  • Use silicone seam sealer
  • Use nylon patches for mending patches or tears
  • Use spray coating for increasing the waterproofness of your tent


Tents are necessary if you want to camp out alone or with your family. It is better to take one big tent rather than carrying multiple tents.

But Rei Kingdom 8 provides great weather protection in less price as compared to its competitor. However, it is not that easy to setup and it does feel a bit cramped for 8 people.
