Compare the Big Agnes Copper Spur UL2 mtnGLO and Tiger Wall UL2 backpacking tents. We break down the key differences to help you choose the right ultralight 2-person tent for your adventures.
Quick answer
Choose the Copper Spur UL2 mtnGLO if you want integrated tent lighting and a proven freestanding design. Choose the Tiger Wall UL2 if your top priority is saving weight and you prefer a side-entry layout.
Lighting vs. weight: the core trade-off
The most obvious difference between these two Big Agnes tents is the built-in mtnGLO light system on the Copper Spur UL2 mtnGLO. This overhead LED system lets you light up the interior without fumbling for a headlamp, which is a genuine convenience on dark nights or when you're setting up camp late. The Tiger Wall UL2 skips this feature to save weight, making it the lighter option for gram-conscious backpackers.
Both tents use Big Agnes' proprietary HyperBead fabric, which the brand says makes them lighter, stronger, and more waterproof than previous versions. So you get the same weather protection regardless of which model you pick.
Entry style and interior feel
The Copper Spur UL2 mtnGLO uses a traditional two-pole, cross-arch design with two doors and two vestibules. This creates a spacious, open interior that many campers find easy to live in. The Tiger Wall UL2 uses a single-pole architecture with large side-entry doors and generous vestibules. This design is popular with minimalists who value a streamlined setup and a lower pack weight.
Your personal preference for entry style matters here. Side-entry tents like the Tiger Wall can feel more efficient when you're crawling in and out, while the Copper Spur's more traditional layout may feel roomier for two people sitting up.
