The two tents at the center of every ultralight debate. The Duplex is a Dyneema single-wall that chases the lowest possible weight, and the X-Mid 2 is a double-wall silpoly tent that gives up ounces to win on space, weather manners, and price.

Highlighted cells mark the better spec: Duplex in blue, X-Mid 2 in amber. A blank spec is never counted as a win. Every headline number is per person, so different capacities compare fairly. GearScore is the overall rating (0 to 100); re-weight it on the full tent comparison. Prices are current MSRP.
This is the classic weight-versus-value decision, and both tents are excellent. The Zpacks Duplex is the Dyneema (DCF) featherweight: it packs the lowest trail weight of almost any two-person shelter, does not sag when wet, and is the pick for thru-hikers counting every gram. The Durston X-Mid 2 is the value and practicality champion: a proper double-wall design that manages condensation better, pitches easily thanks to its offset-pole geometry, and gives you more floor and two vestibules for less than half the price.
The numbers frame it cleanly. The Duplex is far lighter and packs smaller, the reward for its Dyneema build. The X-Mid 2 answers with more floor area, a double-wall that fights condensation, and a price that undercuts the Duplex by hundreds of dollars. Both use trekking poles, both sleep two, and both pitch taut once you learn them. What you are really buying is Dyneema weight savings against silpoly space and value.
Pick the Duplex if low weight is the whole point, you are comfortable managing a single-wall in humid conditions, and the DCF premium is worth it to you. Pick the X-Mid 2 if you want the most tent for your money, a roomier double-wall that handles condensation and weather with less fuss, and you do not mind carrying a bit more. For most buyers the X-Mid 2 is the smarter spend; for gram-obsessed thru-hikers the Duplex still rules.
The Zpacks Duplex, by a wide margin. Its Dyneema Composite Fabric build makes it one of the lightest two-person shelters made, several ounces under the X-Mid 2. That weight saving is the Duplex’s whole reason for being, and why it costs what it does.
The Durston X-Mid 2. It is a double-wall tent, so an inner canopy separates you from the outer fly where condensation forms, which keeps it off your bag. The Duplex is single-wall Dyneema, so in humid or still conditions you manage condensation with ventilation and a bit of technique.
Only if weight is your priority. The Duplex buys you Dyneema and the lowest trail weight, which matters most to thru-hikers and gram-counters. If you weigh value, floor space, and easy weather manners more than a few ounces, the X-Mid 2 delivers more tent for far less money.
