Rated 5 out of 5 by from Perfect backpacking tent I bought this tent last summer during the 4th of July sale. Got an awesome deal. I backpack in WA state. I've had some issues with the tent spikes coming up during a wind storm, but I'll strike that up to user error. The tent fits great in my pack. Keeps me very dry in all our rain and I think the weight is awesome. I picked it up once and literally threw it in the air. Floated like a kite in the breeze. Man they have come a LONG way with tents. The lights inside are a nice added luxury. It has nice inside pockets for things you need quick in the middle of the night. And I can pop the tent up up in under 5 minutes. All and all a rad deal. Amazing tent. Can't wait for another summer of fun!

Rated 5 out of 5 by from Lives up to it's reputation I read a lot of reviews before purchasing a tent. I have owned many in the past. I was looking for something that sleeps 2, 2 entrances, 3 season and very light. This tent sleeps 1.5 comfortable, two is a squeeze. Since I usually camp alone the tent fits fine. With my wife we would be very tight. The vestibule on both sides is handy for storing a few items, I wouldn't count on putting the gear for two people in them. One person, no problem storing. I was on a two night campout with Boy Scouts a fe weeks ago. It was cold and wet and the tent was a champ. We had buckets of rain at times and everything inside remained bone dry. It led to a great nights sleep.

Rated 4 out of 5 by from Great tent, even for two Used this tent on a 3 day backpack trip to Havasu Falls. Temperatures were cool and we had rain one night. This tent held up very well and was nice and cozy inside. It vents well so there was no excessive condensation inside. It sets up easily and quickly and is light to carry on the backpack. Our two Big Agnes sleeping bags and pads fit well side by side with enough room at the top for our packs. And the built in lights are very handy. The only cons - if there are rain drops on the fly and you zipper open the door the rain runs right into the tent and onto the sleeping bags, sometimes the door zipper sticks and the battery case for the lights broke the first time it was opened. I am happy with this purchase and would recommend this tent.

Rated 5 out of 5 by from Great Tent for Backpacking This tent was great for our couple night backpacking trip near the Twin Cities in Minnesota. We had a nasty storm roll through which had 60mph winds plus heavy rains and the tent stood up to it all. Because we were about 100ft into the woods, we were somewhat protected but had issues of branches coming down on us due to the winds. Through all of this the tent held up and we had NO water coming in whatsoever, even without the footprint that night. The MNTGLO feature is really nice when it gets dark but make sure to unplug the battery case when storing the tent. If the USB connector is left plugged in the battery will be drained for next use leaving you an unhappy MNTGLO camper... Overall the tent is great due to the size, weight, and ability to withstand a serious storm. I would highly recommend it!

Rated 5 out of 5 by from Great lightweight tent Went to Rocky Mountain National Park and Canyonlands in Utah last week with this tent. This tent was so light i really forgot that I had a tent in my backpack. Easy to setup and tear down. The back of the battery pack on the mtnglo broke (???) so I had to use my handy dandy duct tape to patch it together so the batteries wouldn't fall out. Other than that one issue, I would definitely recommend this tent.

Rated 5 out of 5 by from Liking this tent Just back from a two day trip in cold, wet, and windy weather. It rained hard both nights with continuous 25 mph winds and some major gusts. No water leakage at all and while the tent flexed a little on big gusts, there were no problems and that's with only "guying" out the four corners, the vestibules, and one line on each side wall using the included 8 stakes. Tent weighs just over 4 lbs which to me is the only negative but if your splitting weight between two people, that not bad. Since I carry it alone, I'd like to move to an ultralight. I'm 5'11" and there is plenty of room to stretch out and store all my gear inside. The MtnGlo system is a nice touch and I find myself using it often especially when adjusting my sleep system in the middle of the night. So much easier that having to aim a flashlight or headlamp.

Rated 5 out of 5 by from Tremendous Backpacking Tent This is a great product: Lightweight, sturdy, plenty of head room, and the integrated lighting is a great feature. Pros: Quick to set up. Plenty of room for two, but light enough that it can be viably used by one person who desires extra space on a longer trip. Nice gear storage pockets on inside. Well ventilated; no condensation build up on inside. Stands up to the most severe rain / wind storms, keeping occupant bone dry at all times. Very cool to have adjustable, integrated, ambient lighting rather than having to use a lantern or headlamp when accessing / organizing gear at night. Cons: Zipper cover on rain fly has a tendency to get caught in zipper. Tip: When rain fly gets wet it will sag a bit, and if not sufficiently taut, has a tendency to make contact with tent mesh. Make sure to use the adjustable straps to tighten up fly (straps located at all 4 connection points) when inclement weather is expected. Overall, this is an exceptional tent, worth every penny.

Would this be a great tent, for me and my girlfriend while we be hinking down the Grand CANYON. It would be for next month. And are they lights included aswell with the tent ?

Asked by: Pete187
The Rattlesnake SL 2 mtnGLO Tent is a great choice for the Grand Canyon. The tent does have built-in LED lights.

Can I fit 2 Big Agnes Double Z sleeping pads side by side in the Rattlesnake SL2? My pads measure 25x78. It looks like it will be a tight fit.

Asked by: windypilot
The pads would not fit very well. One pad would have to lay on top of the other pad for most of the tent's length. The head of the tent is 52" wide. Just enough for the two 25" pads. The tent tapers down to 42" at the foot. This would work for 20" pad.

The lights are built into the tent so... if the LED lights should fail (or one of them), can the light string be replaced or are they permanently out?

Asked by: spazerien
The LED lights on the Rattlesnake SL 2 mtnGLO Tent should last the life of the user in terms of them never burning out. If any of the lights malfunction or get damaged, Big Agnes can replace the entire strand. If one light gets damaged for example, the remaining lights will still function normally. Big Agnes recommends using the tent for the remainder of the season and sending the tent back to them in the winter months as the summer is their busiest season.
