Mountain Hardwear Nimbus UL 2 Tent

What We Think

At 2.3 pounds, the Mountain Hardwear Nimbus UL 2 sits in the sweet spot where legitimate ultralight performance meets livable shelter, and it does so without the compromises that plague many sub-3-pound tents.

This double-wall design scored a 8.2 overall, earning that mark through a combination of genuinely impressive setup speed, solid weather protection, and a weight that disappears in your pack.

The "2" in the name is technically accurate but practically optimistic, something we'll address honestly below.

Ease of Use

The Nimbus UL 2 scored a 9.0 in Ease of Use, and owners consistently back this up.

Mountain Hardwear's G-Hook pole attachment system is the star here, replacing traditional clips with a faster, more intuitive connection that also lets the tent pack down smaller.

The five-minute setup time is real, not marketing math, with multiple owners reporting they've pitched it solo in fading light on their first attempt.

DAC Featherlight NFL poles are the industry standard for a reason: strong, light, and reliable enough that you stop thinking about them.

Weather Resistance

The 1,200mm silicone-coated rainfly handles three-season conditions with confidence, earning a 8.5 in Weather Resistance.

That rating is solid for typical mountain weather, though it's not the tent you want in a sustained coastal storm.

The double-wall construction and three-quarter mesh canopy balance ventilation against condensation management well, a tradeoff that trips up many ultralight competitors.

Value for Money

At $460, the Nimbus UL 2 scored a 8.5 in Value for Money, landing in competitive territory against the ultralight field.

The NEMO Hornet OSMO Ultralight 2P runs $20 more and shaves off a couple ounces, but gives up some storm-worthiness with its single-wall design.

The REI Co-op Flash Air 1 undercuts this tent significantly at $329 and weighs just 1 pound 6 ounces, but it's a true solo shelter with less weather protection.

Mountain Hardwear's Limited Lifetime Warranty adds genuine long-term value here.

Quality & Durability

The 40D nylon ripstop floor with 1,500mm waterproofing is meaningfully burlier than the 20D floors common in this weight class, which matters on rocky terrain.

The tent scored a 7.3 in Quality & Durability, reflecting the inherent tradeoffs of ultralight fabrics, but owners consistently praise the DAC pole strength and report the shelter holding up over multiple seasons.

Space & Comfort

Here's the honest weakness: the Nimbus UL 2 scored a 7.0 in Space & Comfort, and owners consistently flag that two adults is a tight squeeze.

The 28.1 square feet of floor space and 41-inch peak height work well for a solo hiker with gear, but couples report bumping elbows.

The single door compounds this, a recurring theme in negative reviews is the awkward entry when your tent-mate is already inside.

The 7.7 square-foot vestibule is modest but functional for boots and a pack.

User Reviews

Owner feedback is notably positive, earning a 9.0 in User Reviews.

The most common praise centers on how the ultralight design makes long miles feel easier, with the G-Hook system specifically called out for improving pack compressibility.

Who It's For

Solo backpackers who want a legitimate ultralight shelter without the durability anxiety of sub-2-pound designs will find the Nimbus UL 2 hits the mark.

It's ideal for thru-hikers, fastpackers, and anyone who counts ounces but still wants to sit up inside their tent.

If you're truly solo-focused and want to save weight and money, the Mountain Hardwear Nimbus UL 1 drops to 1.9 pounds at $420.

The Bottom Line

The Mountain Hardwear Nimbus UL 2 delivers on the ultralight promise without the usual compromises in weather protection or setup sanity, earning its 8.2 score.

The single door and snug two-person fit are real limitations, so think of this as a roomy solo tent rather than a true two-person shelter.

For backpackers who prioritize trail weight and fast camps, it's a smart investment.
