Why We Like The Nimbus UL 1 Tent

We like to stay light and fast on the trail with the Nimbus UL 1 Tent in our pack. Mountain Hardwear may have simplified and streamlined some features in order to shave weight, but this rugged shelter boasts superior tear strength to give us reliable reprieve from harrowing storms on the trail. Plus, a translucent rainfly not only protects us as drops begin to fall, but also gives us a portal through which to watch the thunder clouds pass overhead.

A Travel Warrior

What an amazing tent. I used it 31 times on a three month trip from New Zealand's South Island to the Philippines, including five urban camps. It is strong, flexible and completely rain tight thanks to a well fashioned rain fly. Easy to set up and pack, great in a storm with more than enough room for my 6" frame, I was impressed

Great design, ultra light.

Got this tent for a trip in the grand canyon of the Yosemite. I needed a lightweight durable one. I love it. Spacious enough for me, I'm 6ft, very easy to setup and pack, well designed. We got some rain and it handled it perfectly. Vestibule is on the small side but functional.

Sturdy bad boy

Had 4 beautiful nights in the Hoover Wilderness with this little bad boy: Mountain Hardware’s Nimbus UL 1. We were turned back at Return Pass due to snow so made the best of it and camped just below the pass, West Lake, East Lake and Green Lake. It was incredibly windy, gusting to 40 MPH - white caps on all three lakes. The sleek form factor of the Nimbus UL 1pitched away rom the wind didn’t budge. At age 67, with a 38L pack and 1/2 size bear can, I greatly appreciated the Nimbus UL 1s light weight (less than 2lbs) and small form factor. Great job Mountain Hardware Design Team!!!

Great light single tent for backpacking

Used this on a five-night pack trip in Idaho. It's light weight and easy to pack and set up. We had a few nights of good weather, and I slept without the fly on and enjoyed the stars and sunrise. There were two of us on the trip and we chose to go with singles instead of sharing a tent (one of us snores) and I would highly recommend the single set up. We were also camping in places that a larger tent would have been more challenging to find a big enough place/flat level ground without big rocks. The small narrow footprint made it much easier to find a flat, level, rock free spot. We had one day of rain and were able to place these in spots under trees with added protection from the wind and rain. Just made for a better experience. The tents stayed dry in 8hrs of continuous rain. Ultimately for this trip the best service this tent provided was escape from mosquitos that were relentless. The tent had good room for me and some of my gear. I'm 6' about 190lbs and it was long enough for me to fully stretch out on my stomach with my feet extended flat and my arm over my head. This will definitely continue to be my first choice for lightweight backpacking.

The little tent that could

I took this tent into an environment that was well out of its league....I had one of those freak summer alpine storms blow through at 6200 feet up Mt Baker and was stuck pitching, and then riding out the 2 day storm in this tent. The rainfall was very high, winds were sustained 25mph with 40mph gusts and the temps dropped about 25 degrees leaving me riding out this storm in summer gear while my water sources froze and most of my other gear wetted out. Do I wish I taken a treeline tent instead of a backpacking tent? Yes. Did this tent do perfectly in those conditions? No. Did it perform better than I thought it would? Absolutely. Some of the other reviewers mention water issues, but if you actually pitch it well and guy it out correctly, the only water entering the tent is splashing up from under the fly. This should be expected in a serious storm, because the fly does not go to the ground, like nearly all other backpacking tents. Another benefit, if this tent is when pitched well, it withstood some serious wind, even in the absence of decent attachments for the fly to the poles. Although, that part was a pain, but again, the little tent that could was far out of its element. The single pole design on the foot end of the tent needed some babysitting through the worst of it, but it never came down on me. Likes: The fly is solid, easy to get in/out of, big enough for what it is Dislikes: fly to pole attachments, overhead pocket is kinda worthless, issues getting it to work well with the footprint (this one could very well be user error)

Quick to Set-Up

Used only for a short trip, so far, but the tent is easy to set-up with plenty of space for one (6’ tall). Quality seems good. The rain fly is fairly snug fit, but should be fine for summer and fall thunderstorms.

Compact and efficient

Nice little tent fits exactly 1 person. I'm 6'2" and I fit just right head to toe. The vestibule is small, but functional; a good enough size for light weight backpacking.

CDT Tent

Ultimately, if I could purchase a tent again for thru-hiking the CDT, I'd probably but a tent that I could use my poles with didn't come in parts (rainfly and tent) to help in wet weather. Also a learning curve with the set-up. I definitely had a nice puddle at the feet after our first storm, but luckily I'm not very tall and my pup curls up by my knees. I'll probably buy a waterproof spray before I head back out, just to be safe.

Kept me and my gear in gnarly Colorado weather.

Took the tent with footprint on a 3 day backpacking trip in Colorado in June. The weight was ultra light and was the envy of the other guys I hiked in with. It rained/hailed/sleeted/snowed every day. My sleeping bag and pad stayed dry in the sleeping compartment and my 65L pack and hiking boots stayed dry in the vestibule. I’m 6’5 and fit inside comfortably with a long and wide sleeping pad and long sleeping bag.
