Sea to Summit Telos Evo
Sea to Summit's Tension Ridge is the one genuinely novel pole idea in mainstream tents: the ridge pole bends upward rather than down, which pushes the door tops out and turns the usual sloping tent doorway into something closer to a rectangle. The Telos Evo pairs that with 19.4 square feet of vestibule and a stated non-PFAS fabric set. Note that Sea to Summit's own listing carries a unit-conversion error in the floor area — 2.6 m² is 28 square feet, not the 84.65 the page prints — so the figure here is converted from the metric number.
Best for
Backpackers who spend time sitting in the tent and want the interior volume rather than the lowest weight.
Durston X-Dome 2
Durston's freestanding tent, for people who liked the X-Mid's numbers but camp on platforms and slabs. Thirty-two square feet on an 88 by 52 inch floor, 18 square feet of vestibule, 3500 mm on both fabrics, and carbon poles that bring it in at 44 ounces — genuinely freestanding with no mandatory stakes. It is thirteen ounces heavier and $200 dearer than the X-Mid 2, which is the price of not needing trekking poles.
Best for
Someone who wants X-Mid-class space and fabric specs but pitches on wooden platforms or rock.
Rows where the two differ are tinted. Specs are the makers’ own; floor area per person, weight per person and pad fit are our arithmetic on them.
