I'm trying to decide between the cuben MLD Duomid vs the Zpacks Duplex Tarp as a 3-(4ish) season shelter. To be clear, I'm only looking at the tarp version of the Duplex since I normally sleep in a bivy/cowboy camp. This shelter would only be used in inclement weather such as rain, wind, or snow. What's everyone's experience on the two?
My primary stomping grounds are in Northern California and the Sierra Nevada range. Occasionally I backpack on the California coastal range. I do both solo hiking as well as with another buddy, hence why I'm looking for a lightweight option to accommodate two.
Thoughts? Further clarifications?
