Copper Spur HV UL1
Big Agnes Copper Spur HV UL1 Review
Tested and reviewed for bikepacking use
The Copper Spur is the gold standard for ultralight solo tents. The high-volume hubbed pole design creates surprisingly livable interior space for a sub-1kg tent. The bikepacking-specific version distributes into three stuff sacks that fit in a handlebar roll.
If there's one tent that has earned "default recommendation" status in the bikepacking community, it's the Big Agnes Copper Spur HV UL1. It's not the lightest, not the cheapest, and not the most bombproof — but it hits the sweet spot of livability, weight, and packability that makes it the right choice for the widest range of bikepackers.
The "HV" stands for High Volume, and you feel it immediately when you crawl inside. The hubbed pole design pushes the tent walls outward, creating steep sidewalls that give you genuine sitting-up room. Compared to narrow tapered tents like the Nemo Hornet, the Copper Spur feels like a palace. For riders over 5'10", this extra volume is the difference between tolerating your shelter and actually being comfortable in it.
Big Agnes made a brilliant decision with the bikepacking-specific version: it splits into three separate stuff sacks. The tent body, fly, and poles each get their own sack, so you can distribute them across your handlebar roll, frame bag, and seat bag. This solves one of the biggest problems with carrying a tent while bikepacking — you don't need one huge stuff sack that only fits in one location.
Setup is fast and intuitive. The color-coded clips snap onto the hubbed pole structure in seconds. We've pitched this tent in the dark after 14-hour riding days and never fumbled the setup. The two-door, two-vestibule design means you can stash muddy shoes and cooking gear in the vestibule without blocking your entry.
The 936g weight puts it in the ultralight category without resorting to the extreme fabric choices (like Dyneema) that push prices toward $600-800. You're getting a fully featured double-wall tent — inner mesh body plus waterproof fly — which means excellent condensation management compared to single-wall alternatives.
The trade-offs are real, though. At $400, this is a serious investment. The fabric is thin — you need to clear your campsite of sharp objects, and a stray branch can punch through. And while the tent has a freestanding pole structure, it really needs stakes to achieve the proper pitch, especially in wind. Carry at least six stakes and you'll be fine.
For bikepackers doing multi-day routes in three-season conditions — which is the vast majority of bikepacking trips — the Copper Spur HV UL1 remains our top tent recommendation.
Who Is the Big Agnes Copper Spur HV UL1 Best For?
Ultralight bikepackers who want a real tent, not a tarp. If that describes your riding style, the Copper Spur HV UL1 should be at the top of your shortlist. It sits in the Shelters & Tents category alongside 11other products we've reviewed.
How It Compares
