Lighthouse

Most of the time I use this as a solo tent, plenty of room for all my gear and myself.
But if need be I have room for a roomie. It's long enough to store some gear at my feet. All at a size and weight that rivals many solo shelters.

Even though its not considered to be waterproof, I have held up inside during a couple sierra storms and have remained completely dry.

I have this one. Very light and very sturdy. The big opening door makes climbing in and out easy with a partner. The interior poles keep it tight and provide good space without sagging.

One gripe: I swear it was advertised as waterproof back when I bought it as I was specifically looking for a waterproof tent to replace my water repelant tent at the time. Nevertheless I can't comment on the quality of the water repelancy since I have not been caught in the rain with it yet.

I've been through about three rainstorms in mine so far with no leaks. Seam sealing at least the roof seams is required; otherwise you will get a fine mist falling inside the tent as drops hit the seams. Condensation forms inside on rainy nights, but I have yet to sleep in a tent that avoids this. I find the size workable for two people and a bunch of gear. I haven't used this tent for snow/winter camping or in high winds yet.

Pros:
Very light for a freestanding tent (about the same as 2 bivy sacks).
Setup is a snap.
Huge door makes it pleasant in fair weather.

Cons:
Expensive.
Long-term waterproofness/durability of Epic fabric unknown.
Seam sealing required (though some of us enjoy working on our gear).

Bought this as a mountaineering tent (thanks Backcountry magazine!) and was appalled- it was a liability in all conditions except absolutely still, sunny days. The Lighthouse "resisted" rain/snow for only one night, had problems with condensation, and tore repeatedly (granted, I set it up quickly- but conditions often dictate this and a tent shouldn't have to be babied constantly).
$350 for this (not to mention having to seam seal it myself)? I'll carry a few more pounds in return for confidence in my shelter.

I've had my Lighthouse for just over a year now so this is kind of a long term review. I'll start off by saying that I'm pretty cheap, I generally don't upgrade to the latest and greatest until I can find it used. This is one of the few pieces of gear I've ever bought new.

The tent was expensive, and they weren't able to sell it in California and a few other states, so I had it shipped to a cousin in Oregon who mailed it down to me. First thing I noticed was how light it was, and how nicely it compacted when in the pack.

The second thing I noticed was that I had to seam seal it myself. For that price I was hoping for BD to have already handled that.

The tent is easy and quick to setup, roomy enough for two people and their gear for days at a time and easy to take down. Just like about every tent I've been in, you'll likely wake up with condensation after a relatively humid night. With the screen door up the ventilation is great for stinky partners and that always seemed to alleviate the condensation as well.

I've been dumped on twice in this tent, both times with snow and it held up well, the snow was efficiently shed off the tent both times. I haven't been rained on yet, just lucky I guess.

PROS:
Light
Easy to setup/takedown
Light
Sturdy
Pretty roomy

CONS:
Expensive

Lightweight but reasonably roomy for a two person especially with vestabule. Very light material requires care when using. Careful seam sealing has kept me dry so far.

I bought this to use as a 4 season shelter and ended up taking it back. I liked the light weight and solid feel after pitching but it seemed to gather more condensation than my other single wall tent. I don't quite trust it for harsh winter conditions. Great but not quite what I was looking for.
