Zpacks Duplex
The Duplex is the tent the Pacific Crest Trail standardised on, and its numbers explain why: 17.8 ounces, 28.1 square feet, a 90-inch floor, two side entries with overlapping storm doors, and a pitch that takes six stakes and two 48-inch poles. It is single-wall, which is the whole compromise — there is no inner to catch condensation, so on a still, humid night the walls are wet and you wipe them. Zpacks sells the 3-person as the Triplex, which at 38.4 square feet and 21.7 ounces is the most floor per ounce of any tent in this catalog.
Best for
Long-trail hikers who will pitch it two hundred nights and want the weight gone.
Hyperlite Mountain Gear Unbound 2
Hyperlite's first fully enclosed two-person tent, and the one that competes directly with the Duplex: 22 ounces, 28 square feet, a 90 by 48 inch bathtub floor, two doors and two vestibules, pitched on two 125 cm trekking poles. The extra four ounces over the Duplex buy a taller 48-inch peak and a more heavily vented canopy, which is Hyperlite's answer to the single-wall condensation problem. The company publishes almost none of this on the product page — floor area, peak height and pack size all come from independent reviews — which at $795 is a genuine annoyance.
Best for
A Dyneema buyer who wants more venting than a bare Duplex and does not mind paying for it.
