The Sheep Mountain 3 has two doors and a peak center height of 3' 10, which is a tiny bit smaller than the average height of the 175 different 3 person tents we have examined With 44 square feet of space inside, it is a little bit smaller than some other 3-person tents, and it could be a little tight for you and, up to two other campers during the 3-seasons, this tent is suggested for use in, smaller tents similar to this one are a fantastic choice for people who enjoy spending plenty of hours outside exploring the great outdoors.

A few of the fantastic things about dome tents are, that they are generally speaking not too heavy, making them simple to carry around. In most all cases, tents used for backpacking are of the dome type. They are usually, freestanding and very simple to set up. In good weather, you could do without guy lines and stakes, not that this is suggested.

Dome tents are without a doubt the most common of all the different sorts of tents you will find when camping. They tend to fair better in bad weather than other types, allowing rain to easily slide off the sloped walls, unlike cabin tents that have flat tops, allowing the water to pool on the roof. The most straightforward dome tent should have a rectangular footprint, sloped sides a couple of poles which converge in the center of the roof. Due to their construction, it is usually thought of that they are best suited for up to a maximum of 6 people.

Below you can find an account of the tent's pros and cons.

Click or Tap on the Tab you Want to See!


  1. Freestanding. The Sheep Mountain can support its own weight on any terrain. It does not need to be staked down in most cases. But in case of strong winds, it is always best to secure it to the floor with the included steel stakes and guylines.
  2. Vestibules. Having two vestibules. Gives you somewhere to store shoes and other items that can get dirty, muddy, this is a huge plus.
  3. Internal storage. It is good to see Big Agnes has added a gear loft and pockets in the interior to store some of your gear.
  4. More than one door. With 2 doors, it is easier to get in and out of the tent, in the middle of the night if needed.
  5. The rainfly completely covers the tent body. The rainfly covers the entire body of the tent from the top to the bottom and has a waterproof rating of 1500mm. Meaning it will easily protect you against heavy downpours.
  6. Available in other sizes. Big Agnes has also made this model available in Other Sizes.
  7. Low price. It is a great deal for a 3 person dome tent providing this much room. Not a lot of tents available on the market provide this level of quality for only $379.95


  1. Not roomy. With a floor area of 44 square feet, the Sheep Mountain 3 is smaller than quite a lot of the 180 other 3 person tents we have looked at.
  2. Lacking in Headroom. With 5% less headroom than similar sized tents, one can see how this could be a negative thing for some campers.
  3. Footprint not Included. There is no included footprint, The floor may be made of Polyester Oxford but it is still best to protect it further with a footprint, more so on rough terrain.
  4. Out of Stock. Unfortunately this particular tent is not currently in stock. It is still on the manufactures site the last time we checked.
  5. A little heavy for backpacking. Even though the Sheep Mountain 3, looks like a small tent, it is not ideal for backpacking as it weighs 8 pounds. This is quite a lot more than many other backpacking tents
  6. Sloping walls. Even though Dome tents have heaps of qualities to be positive about. The sloping walls do tend to make it all the more smaller inside.


4.3 Stars Logo

Our Ratings: 4.3 STARS

Big Agnes's Sheep Mountain 3 tent is ideal for bicycle & motorbike camping. Here are a couple of other nice points not already mentioned above which, were found and liked, while researching the model: Doors have two closure options: Zip up mesh door for ventilation or zip up the breathable layer for full protection, Fly vents allow for venting in inclement weather and Ready to pitch; with pre-cut guy lines and tensioners attached to fly.

With great ratings, and headroom of 3' and 44 square feet of area to sleep, this tent is like your very own little apartment. It will allow you to spend some delightful moments exploring the great outdoors. We found more positive points than cons about the tent that you can read through above.

If you found this website looking for an endorsement on this actual tent, we think, it should make for a great purchase. If you just happened to arrive on this page while looking for a brand new tent having not heard of this manufacture or this tent model previously, it is perhaps a good idea to look at some other similar tents also.

Value for money: As far as value for money, this tent is a more competitive than the normal cost of all the one hundred and seventy-five, three-person tents we have studied, all alone this does not make it awesome value for money. We also need to look at other areas in detail, as we do with every tent.

When we determine the valuation of a single tent, we scrutinize a lot of areas, looking for things where the tent could shine against other very similar tents and where it is lacking. In this case, with a total rating of 4.3 and the price details above, It is simple enough to recognize that with a price point of $379.95 The Sheep Mountain 3 is a decent purchase and astonishingly priced when compared with similar tents.

Its overall score shows that the build and size the tent provides were not compromised to arrive at a price unquestionably beneath the standard price for comparable tents. It could make a remarkable choice for nearly all people looking for an adequate three-season dome tent to camp with, that will serve you well for years to come.
