Just to chime in...
I had mine here in the Grand Canyon for a week long hike in mid April. I used a SpinnTwin for rain protection most nights (it always rains in the desert!).
We had all the weather one could want, snow on the rim, clear nights where I did not need a tarp, rain and snow on the Tonto, winds that made pitching a tarp a formidable task, and great desert blooms.
Some notes on the Bug Tent:
Construction is good throughout.
All seams are tight and no fabric/mesh ends exposed to fray.
All seams are sealed (nice touch) comes with nice vented stuff sack, with a mitten hook so it does not get lost over night.
Water protection afforded by the SylNyl foot end and raised SylNyl at the entrance was sufficient for the rain we saw that blew from every direction (the canyon head walls and sides made the wind shift wildly all night).
I personally would prefer a button and loop system rather than the mitten clip to hold the door open, but that's just me, no biggie.
A stash pocket would be helpful (head lamp, the whistle I have had around my neck all day, small stuff like that).
The zipper for the front door is a bit short. It appears to be a stock size and does not go all the way to the edge of the wall. This makes the door effectively smaller than it could be.
It is a bit heavier than the MLD Serenity Shelter, but you can have it in a week or so, not in a month or month and a half. Good for us planning impaired folks!
All in all, I like it, the business is good to work with. As a thought, having it shipped via FedEx or UPS, as opposed to the USPS shipping would make tracking the package easier and might be worth the bump in costs.
I recommend this gear and would buy from AlpinLite again.
