    It's all about the mood lights.

    There's not too much four people can do in a dark tent on a rainy night, but with the Big Agnes Rattlesnake SL 4 MtnGLO Tent you can mix up some drinks and play some cards, instead of going to bed at 8:30 to wait out the rain. MtnGlo technology consists of a lightweight LED light strand integrated into the canopy of the tent, which can be operated with a three-setting push button remote. The lights can be powered through either three AAA batteries or a USB power source. This four-person option in the Rattlesnake line has room enough for you and three of your best hiking friends, whether they be two or four legged.

    The tent itself is composed of a double-wall design with a PU coated polyester ripstop fabric making up the fly and floor. A mesh canopy keeps the bugs out once the mosquitoes come out to play. The tent has a trail weight of 6lb 8oz, which can be split between hikers to lighten up the load, but it also has a fast pitch option when set up with a footprint (sold separate). The hub pole design maximizes space inside of the tent, and it also puts a steep pitch on the walls so water quickly rolls off the fly during those really rainy nights.

    Head Room

    • Familiarity: I've used it several times

    I have the 3 person tent, which I use for two people. The Copper Spur is lighter, but sitting up comfortably is more important to me, so I bear the extra pound of weight. I definitely love the head room that you get with this.

    The lights are awesome. They have look like moon light, so it feels very natural. Make sure disconnect and turn them off, when not in use. It will eat up your batteries!!

    The tiered side gear stashes are so cool. There are two set of single side stashes, and two sets of two tiered side stashes. There's a hole for your cables, if you want to use it for your phone, or for watching a movie off your device, if that's your thing.

    Everything else has been good. The 360 mesh is awesome for the views. The vestibules have plenty of room for your gear. There isn't a ton of extra room inside the tent, especially if you put 3 people or 2 and a large dog. But, there is some room, especially if you just have two people.

    This is very easy to set up, and the poles and mesh have been strong, so far. Another solid backpacking tent from Big Agnes!

    Head Room

    A great tent for roomy sleeping

    • Familiarity: I've used it once or twice and have initial impressions

    My dad recently acquired one of these and we tested in out on a two-man three-night hike in the Wind River mountains. It was stable during a windy nights and provided the two of us plenty of room. It was not too heavy for the two of us to carry comfortably, though most tent sites we could find were a little bit cramped around the corners.

    The mountain glow feature was neat and unobtrusive, but I wish it were a little brighter; reading still required a headlamp or lantern.

    Unanswered Question

    In reference to Big Agnus Rattlesnake Sl4- Are they designed so you can open the fly in the rain and not have the rain come off the top of the tent. and through the door netting onto the interior floor.? it appears the netting extends out past the lip of the fly if the fly has to be opened in the rain.and. the material below the netting does not come up high enough to block the rain running of the roof either. I just received one from you today and it appears this is the case although I have not tested it yet
