Black Diamond Firstlight 2-Person Tent

I spent two months sleeping in this tent while hitchhiking through europe with a buddy.
For light weight, ease of setup and take-down, functionality, durability, and simplicity, this is the greatest tent i have ever had the pleasure of sleeping in. The tent took a beating (we pitched it everywhere from Irish mountaintops to Spanish parking garages) with nary a tear or loose thread. The zippers pulled snag free every time. The ventilation was effective - I never felt like I couldn't breathe in the tent, as I have in many single and double-walled tents. I have a hunch the bright interior played a role in keeping our morale up throughout the two months. By the end of the trip, I was questioning the value of houses: why not live in a tent for the rest of my life? I would live in no other tent but this one.
I'm 5'11" and my buddy is 6'. We were able to sleep in the tent with our backpacks on rainy days (which there were a lot of). It was admittedly cramped, because our backpacks were huge, but cramped can equal cozy with the right mindset, and I think backpacking in general requires a certain psychological shift that makes you more open to discomfort in exchange for freedom/exploration/escape/whatever reason you are camping to begin with.
The tent leaks in heavy rains. We dealt with it, but some may not want to. Those who say this tent is meant for alpine-style summit assaults are correct-it's better at sheltering you from dry snow than rain. However, if you're not afraid of a few drips, this tent is great for extended backpacking trips. A waterproofing fabric treatment is something else you could look into, however do your research because chemicals in waterproofing treatments could theoretically compromise the integrity of the fabric.

I have spend many nights in a Firstlight and consistently been impressed by its durability. This is a great tent for lighter alpine style climbing as it is light, minimalist and simplistic in design, and very easy to set up in high winds and storm. Designed to be set up from inside is a great feature when you need it. Spent a lot of time in this tent in the Andes and it has always held up against strongest winds I've ever felt.
I would recommend this tent for use in dryer environments or on snow as it is not the best in the rain. Even when new it will get pretty damp in the rain. In addition, as with almost all single wall tents the Firstlight will build up a pretty good amount of condensation on the inside when conditions are right. That being said, this tent will dry out as fast as any in good sun.
I would recommend the ground cloth if planning on using on anything else other than snow. Vestibule is great for cooking when you don't want to leave your bags, and also a great place to store boots/shoes, ect. Another great item I use with all my tents are the Mountain Hardwear Snow & Sand Tent Anchor (Item # MHW0178). I just leave them on the tent lines and they fit right in the stuff sack when I pack it up. The anchors work great if camping on snow.
All in all a great tent, but definitely minimalist. I have taken this tent on quick overnights in the desert, as well as expeditions in the high Andes, and Canadian Rockies. I've had great success with this tent and it will continue to serve as my go to tent for when weight matters.

I really like this tent, it is roomy for one person, cozy for two people and light weight. I am 5'11, by myself I sleep diagonal and am fine with room. With two people my head touches one side and my feet touch the other. My buddy is 6'4 and his feet hang out the door, which is fine because I have the vestibule. Condensation is a pretty big issue, so I will open up the vent, leave the door open and just zip up the vestibule, no problems after that. I have only used the tent above treeline, and never in rain so I can't comment on how it would do in rain, though I would say that I wouldn't want to. On snow, the bottom will wet out a little bit at pressure points where you lay down. It seems to hold up pretty well in the wind, I dead man the tent tie outs and the vestibule tie outs and have never had any worries. The only thing I do not like about this tent is that it just feels flimsy to me as far as the fabric. I am very cautious with it setting it up and breaking it down and where and what I place it on or around. I guess that is the price you pay for the incredible lightness of this tent though. After all was said and done, I would most definitely buy this tent again and would also recommend it to others who are looking for a seriously light tent.

For trips in the mountains where weight is the primary concern and I know that it isn't going to rain this tent is the bees knees.
Like most other reviews point out- you will get wet in a downpour. But for alpine use it is solid, handles wind pretty well, is light and packs well.
For any trip where I anticipate some rain, or having to spend a lot of time sitting in the tent waiting out bad weather I generally use the Ahwahnee.

Has always kept me very comfortable in super cold weather in the snow. Never leaks, won't blow over even in very heavy winds.
Pretty much the best winter tent and about half as light as the competition. My only issue is that it's too short. I'm 6'3" and just barely fit.
Haven't tried it out of the snow but I've heard it leaks and gets condensation. I'd say it's not the right tool for that anyway, get a Tarptent for those trips.

Seriously backcountry? This tent could easily be a four-season mountaineering tent.(maybe not on everest but...) Anyways this is a great tent that packs down small as your food. Love the wasabi color also.

I used and love this tent ...just don't get it to close to any sharp or abrasive rocks
