Eureka Tetragon HD 8 – what this is about
Eureka Tetragon tents is a series that includes tents for 2, 3, 4, 5, and 8 people, so the tent presented here is the largest in the group. Those are dome-shaped tents and they share many common features. But this largest tent is a 2-room structure with a removable divider. This is a bit unusual, not many dome tents are with multiple rooms, but there are indeed a few, you can see this Timber Ridge 8 which also has two rooms.
So this is a well-balanced structure with 12 x 10 ft (366 x 305 cm) dimensions and quite tall for a dome tent with its 76 inches (193 cm) stand-up peak height. The tent is freestanding with two simple poles that create a stable X-shaped structure, see the picture:
Note that the pictures available on Amazon are a bit mixed so you do not see the true picture of the 8-person tent; this given above shows how it looks without the fly, observe the small windows next to the doors, you do not have this in smaller tents in the series. The fly here is a partial-coverage type, so the lower sections of the walls are also built from a waterproof material.
Who is it for
Capacity-wise, you have the area with 120 ft² (11.2 m²) and the declared capacity is 8 people. Below you see what they suggest for using the floor area. This is 15 ft² (1.4 m²) per person, clearly not much, they have used the backpacking principle here. If you are at a summer music festival with your friends, this may work for 8 people. But for a real family camping, this is for parents with two kids maximum. Note that there is no storage area here, the fly has no vestibules.
Seasons-wise, I see it as a summer camping tent, so I would say for 2 seasons maximum but the manufacturer claims it is a 3-season tent. The mesh in the upper part comes good for a warm season camping but not if it is cold. The poles are not particularly durable but the structure is dome-shaped and aerodynamic and it should behave well in windy conditions in spite of such a height. But indeed such a fly is not for strong winds.
Climate-wise, I already mentioned that so much mesh does not keep the warmth, so if this is important for you, check this list of tents for cold weather camping. But the structure is with high panels around and there are no floor vents, so this is not the best for a very warm area.
Weight-wise, with its 18 lb 14 oz (8.56 kg) this tent is quite lightweight. You will realize this from the comparison table below where I show it side by side with some other 8-person tents built in the same style.
The packed size is (L x D) 31 x 8 inches (79 x 20 cm) and this is quite typical, you will realize this from the comparison table below. So you can transport this tent even on a bicycle and a motorbike, but I would not plan to carry it long distances.
Materials & construction
The tent is a two-room structure with a removable divider, and you have two doors on the opposite sides. The divider is a triangular-shaped fabric that you attach to the top (the narrow side up). After that attach it through the toggles to the walls. It is with the central zipper as well.
The poles & stakes
There are two main poles plus two short poles that create small awnings above the doors, this is a 12.7 mm thick fiberglass. You have clips and ring/pin system in the corners for an easy set-up, see the picture below. The stake material is a steel skewer.
The inner tent is 63D 190T polyester taffeta and the waterproof rating for the exposed sections is 1000 mm. The same rating is for the fly which is of the same material and with the same coating. Note that the video below shows 1500 mm, but the numbers I give here are from the manufacturer’s site.
The mesh sections are 40D polyester no-see-um. The floor is also 63D 190T polyester taffeta with 1000 mm rating. This is a bathtub design, and all seams are fully taped. So all in all, the rating is not high but in principle, this holds mainly for the floor; for the rest of the tent, you will not need more.
- Two storage pockets.
- Two gear lofts for essentials off of the tent floor.
- E! Media Center with a touch-friendly TPU center pocket, see the picture above.
- Compatible with Eureka’s Camp Comfort Tent Floor.

The price & rating
The price of this tent as the moment of writing this text is around $209 and I find this very reasonable for such a tent. There are more than 50 reports by customers on Amazon and the tent has received a good 4.0/5 average rating. My rating is slightly higher, I use the same criteria for all the tents here in the site:

Eureka Tetragon HD 8 vs Competitors
I think it is good to see how the tent compares with other brands’ tents built in the same style. So have a look at these two given in the table, as you realize they are with the same floor area but the design is different. The Kelty’s tent is with a full coverage fly, while the NTK tent is something totally unique. See the weight and follow the links to check the updated prices, this will help you in making an informed choice.

Clearly, this Eureka Tetragon HD 8 Tent is nicely built and if you need something for occasional use and do not want to spend much, this is definitely a tent to consider. Bear in mind the features given in the text, and also my objections, so do not expect too much and do not put it in harsh tests. This is a tent for mild weather conditions.
Note that there are many tents from this brand presented here in the site, this is a well-respected brand and they have many popular tents on the market. So check for example their Midori 6 and Eureka Sunrise EX 6 if you want something dome-shaped, or many of their cabin-style tents like the Eureka Copper Canyon Tent 8 and Eureka Desert Canyon 6.
