Real owners rate these about evenly: 84% of 112 Big Agnes Copper Spur HV UL2 owners recommend it, vs 79% of 140 for the MSR Hubba Hubba NX 2-Person.
Verdicts aggregated from Reddit, enthusiast forums, and YouTube owner comments — affiliate reviews excluded. Sample sizes differ; judge accordingly. How we score
Both the MSR Hubba Hubba NX and the Big Agnes Copper Spur HV UL2 earn owner loyalty for being light, quick to pitch, and durable enough to hold up through years of wind and rain, and both draw the same core caveats of a snug fit for two adults and a premium price. Hubba Hubba owners praise its light weight and small pack size, good headroom for one, and how it handles wind and rain, while noting it's cramped for two adults, heavy by ultralight standards, and chilly and airy in cold weather. Copper Spur owners highlight how light it is at around 3 lbs, its livable interior for the weight, dual doors and vestibules, and thoughtful pockets, but caution that the thin fabric, mesh, and zippers are fragile and need care. A backpacker who prioritizes proven weather durability and doesn't mind extra weight leans to the Hubba Hubba, while one wanting maximum livable room and features at the lowest weight, and willing to handle it gently, leans to the Copper Spur. Neither is simply better; the choice hinges on whether rugged weatherproofing or lighter, roomier comfort matters more.
“Big Agnes Copper Spur HV UL2. Upgraded from Marmot Limelight 2p (which is still awesome btw) but saving 3.5 lbs makes a huge difference.”— thatonedayinmay on Reddit
“Get a Big Agnes Copper Spur HV UL2 Bikepack and forget about it. I just did a 8,571-mile cross-country moto trip and camped most of the way, and my Copper Spur was incredible in all kinds of weather.”— lowfox on Reddit
“I’m currently in the older model Big Agnes Copper Spur HV UL2 and am looking to get something else. Every sleeping pad I use in the copper spur sounds like a rubbery balloon squeaking as it rubs against the floor. Not ideal for anyone else sleeping nearby.”— bb-backl8er on Reddit
“I'm beyond excited to get out and use it”— @dudeymcduderson on YouTube
“Vestibules are huge at 8.75sq-ft for a total of 17.5sq-ft.”— CJOttawa on Reddit
“I have a MSR Hubba Hubba, that I use solo. It's definitely small for two people. I don't like that it's pitched inner first, meaning if it rains the inside gets wet.”— oops_whatnow on Reddit
