Weight Comparison
The Big Agnes Copper Spur and Nemo Dagger are both popular two-person tents, but their weights differ significantly. The Big Agnes, without footprint, weighs in at 3.10 lbs, making it noticeably lighter than the Nemo Dagger.

Adding the footprint, an optional accessory for both tents, brings the Big Agnes to a total of approximately 3.10 lbs While the Nemo Dagger weighs approximately 4.10 lbs with its footprint. This weight difference is largely due to construction differences, which we'll discuss later.

Setup and Design
Both tents boast relatively straightforward setups. The Nemo Dagger's poles are a single-piece design, simplifying assembly. The included stakes seem durable, though they may show wear with repeated use.

The Big Agnes Copper Spur utilizes a one-piece pole design as well, but includes a separate, smaller pole piece for the top. While the stakes are lighter, they feel less robust than the Nemo's.

Inner Tent Features
The Nemo Dagger offers a spacious, rectangular inner tent, ideal for two people. Its zippers are smooth and easy to use, and include clips to keep them open. The tent features ample mesh for ventilation and pockets for gear storage.

The Big Agnes Copper Spur's inner tent has a tapered shape, resulting in less floor space, particularly noticeable if using two sleeping pads side-by-side. It features similar convenient features, including mesh windows and pockets.

Rainfly Performance and Ventilation
The Nemo Dagger utilizes Nemo's new Osmo fabric for its rainfly, which appears more durable than previous iterations. Ventilation is achieved through adjustable vents on the doors and the ability to partially or fully open the rainfly.

The Big Agnes Copper Spur's rainfly uses lighter material, impacting its performance in strong winds. Ventilation is handled through vents integrated into the rainfly's design as well as adjustable tabs on the doors.

Wind and Rain Test
A wind test revealed the Nemo Dagger to be more resistant to wind, maintaining its shape even with the doors open. The Big Agnes Copper Spur showed more movement in the wind, despite the stakes being firmly planted.

In a simulated rain test, both tents performed equally well, keeping the interiors dry. Both fabrics effectively repelled water, with minimal moisture retention after an hour.

Gear Storage and Interior Space
Both tents offer ample gear storage. The Nemo Dagger, with its rectangular shape, provides more comfortable interior space for two adults. The Big Agnes Copper Spur, while still comfortable for two, offers less floor space due to its tapered design.

The Big Agnes Copper Spur’s gear loft is a useful addition for organizing items. However, the rectangular floor plan of the Nemo Dagger proves significantly more convenient for two people using larger sleeping pads.

Conclusion
Both the Nemo Dagger and Big Agnes Copper Spur are excellent two-person tents, each with its strengths. The Nemo Dagger excels in its rectangular floor plan and superior wind resistance, making it ideal for two people and windy conditions. The Big Agnes Copper Spur offers a lighter weight solution with similar features, but its wind resistance is less impressive.
The best choice depends on individual priorities. If maximizing interior space and wind resistance are paramount, the Nemo Dagger is the clear winner. If minimizing weight is the key factor, the Big Agnes Copper Spur is a strong contender.
