Comparative Analysis

When comparing the Zpacks Duplex Zip to the Big Agnes Copper Spur HV UL3 and the NEMO Dragonfly Osmo 2, several key differences and similarities emerge that are worth considering for potential buyers.

The Big Agnes Copper Spur HV UL3 is known for its spacious interior and livability, offering ample headroom and vestibule space. It weighs more than the Zpacks Duplex Zip, coming in at around 3 pounds, which is considerably heavier but provides more interior volume and sturdiness.
