Here we go with tent #3, the Six Moon Designs Lunar Duo. When I read on Brett’s Blog that four grown men were able to sit in this tent playing cards while riding out a rain storm on the Wonderland Trail I had to see it in person. Especially since it comes in at under three pounds (41 oz without stakes or poles). It does require 4-6 stakes so add another couple of ounces if you’re counting. Another 4 oz if you’re not using hiking poles and want to buy the optional carbon fiber poles.
This tent is able to deliver massive interior space by using only two small spacer poles curving at the roof and relying on two hiking poles (or optionally two carbon fiber poles that can be purchased separately for those that don’t hike with poles) to be the bones of the tent.
Similar to the Double Rainbow this is a single-walled tent meaning that the mesh sides are sewn directly into the silicon-nylon roof. It has a bathtub floor, gets staked out at the corners and by adjusting the height of the trekking poles you can create tension where you need it instead of with your tent-mate since there is enough room for the whole family. You will likely want to add a few guy lines to this set-up; there are two guy points from which you can add some stability.
While the Lunar Duo doesn’t have a porch option like the Double Rainbow, it does have vestibules on each side large enough for gear. I would be curious to know how this sheds water and wind with its surface area being so large, but it is the same surface area that creates such a huge and comfortable interior so I guess there are tradeoffs. With good staking there is no reason to doubt that this tent can hold up to quite a bit of abuse. Again, a great comparison review has been done of this tent and two others here. All in all this seems like a fantastic option for claustrophobic backpackers who want to make everyone around them envious of their living space.
Cost: (as of May 18th, 2012) the Tent is $310, optional carbon fiber poles are $30 each, optional seam sealing is $30, a Tyvek ground cloth is $12, and a set of 6 stakes is $10.50
Massive. No complaints about the size of this tent. It is the largest of the three reviewed.
Easy to set up once you get the hang of it.
The zippers are the sturdiest (#5s) of any of the three tents.
Made in the USA
Unless you have good firm dirt to plant your stakes in, keeping it tensioned might be a problem. I guess that’s where rocks come in.
Relies on hiking poles or extra carbon fiber poles which add to the weight by about 4 oz.
