Tent Set Up

Summary: Favorable Reviews

Campers mentioned It stands up to 30-35 mph wind, pouring rain without a single leak. I love the benefit of the light system on the inside. Light, sturdy, sets up, breaks down, and packs quickly and full of great features. I had to set this tent up using mostly moon-light. It was a breeze. One day it dumped buckets of rain, yet the inside stayed warm and dry. Side entry was grand, and the vestibule is roomy, comfortable to access from within the tent, and kept my bags dry during a storm.

Summary: Unfavorable Reviews

Reviews said Zippers are not that tough. I'm 5'9" tall, and the tent is perfect. If I were 6' or taller, I might not be happy in it. If you want the rain fly to be useful, you'll need to be able to stake it out. The only issue I have is the wiring on the light system is messed up, so I have to exchange it for a new one, so be careful with that feature while packing it up.

The Rattlesnake 3 SL mtnGLO has two doors and a maximum center height of 3' 13, which is a little bit less than the average height of the 128 different 3 person tents we have examined With 43 square feet of room inside, it is a lot smaller than some other 3-person tents, and it would be quite tight for you and, up to two other campers during the whole of the 3-seasons, this tent is approved for use in, smaller tents similar to this one can generally make an awesome choice for people that enjoy spending lots of time outside of the tent enjoying the fresh air.

Many of the cool things about dome tents are, that they are under normal circumstances lightweight, making them easy to carry around. In nearly all instances, tents used for backpacking are of the dome type. They are usually, freestanding and very easy to set up. In good weather, you could do without securing the tent with stakes and ropes, not that this is recommended.

Dome tents are easily the most common of all the various sorts of tents you will see when camping. They tend to do better in the rain than other types, allowing rain to easily slide off the sloped sides, unlike cabin tents that have flat tops, allowing the rain to pool on the top. The most straightforward dome tent should have a square floor, sloped sides a couple of poles which cross in the middle of the roof. Due to the way they are made, it is generally considered that they are ideal for up to a maximum of 6 people.

Beneath you can check out a list of the tent's pros and cons.

  1. Freestanding. The Rattlesnake SL mtnGLO can support its own weight on any terrain. It does not even have 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. Offers you a place to store shoes and other things 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 things.
  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 whole body of the tent from the top to the bottom and has a waterproof rating of 0mm. Meaning it will easily protect you against heavy downpours.
  6. Other sizes are available. Big Agnes has also made this model available in Other Sizes.


  1. Not roomy. With a floor area of 43 square feet, the Rattlesnake 3 is smaller than quite a few of the 128 other 3 person tents we have looked at.
  2. Lacking in Headroom. With 8% less headroom than similar sized tents, one can see how this could be a negative factor for some campers.
  3. Footprint not Included. There is no included footprint, The floor may be made of Ripstop nylon but it is still best to protect it further with a footprint, especially on rough terrain.
  4. Discontinued: Unfortunately this particular tent has been discontinued on the manufactures website and is not available elsewhere, that we are aware of.
  5. Sloping walls. Even though Dome tents have heaps of qualities to rave about. The sloping walls do tend to make it all the more smaller inside.

Value for money: When contemplating value for your money, this tent is tad bit more competitive than the average price of all the one hundred and eighty-two, three-person tents we have taken a look at, all alone this does not make it good value for money. One should also take into account other areas in detail, as we do with each tent.

When we calculate the score of a single tent, we study a lot of conditions, looking for points where the tent could shine against other comparable tents and where it is coming up short.
