Big AgnesTiger Wall UL2
While my specific tent from Big Agnes isn't available anymore, the Tiger Wall UL2 is comparable and I'd highly recommend it. It's lightweight, sturdy, and will be the perfect tent for any backpacker looking to put miles between themself and civilization.
Big Agnes sets the bar when it comes to backpacking equipment. I've had my current tent for three years and it's still tough and reliable as ever. When looking for a backcountry tent, staying around or below the three-pound mark will make your back happy.
The Tiger Wall UL2 is definitely below that weight limit and is packed with features. However, be prepared to pay a pretty penny as these are a true investment.
