Gossamer Gear The One vs NEMO Hornet OSMO Ultralight 1P
Two shelters, measured against each other on the figures that decide whether they work on a bike.
The short answer
The The One takes weight, headroom and price; the Hornet OSMO Ultralight 1P takes pitching on hard ground and floor space. On a bike the pole set usually decides it before the rest do.
Assembled from the differences below rather than written over them. Every figure is a published measurement or computed from one — nobody here has used either one.
Where they differ
7 of the 7 things we can measure come out differently.
Poles to carry
the The One has no pole set at all, the Hornet OSMO Ultralight 1P doesA trekking-pole shelter has nothing to fit across your bars, which removes the constraint entirely — but you then need poles from somewhere, strapped to the frame or bought separately. It is a different problem, not a smaller one.
Minimum weight
264g lighter on the The OneTrail weight where the maker publishes one — fly, inner and poles, without the stuff sacks or the footprint. Worth reading against the pole length rather than instead of it: a Bikepack edition is usually a few grams heavier for shorter poles.
Construction
Hornet OSMO Ultralight 1P is double wall, The One is singleA double wall puts a gap between you and the condensation; a single wall saves the weight of the second layer and puts the condensation on the inside of your shelter. Which is right depends on where you sleep, not on which is better.
Pitching
Hornet OSMO Ultralight 1P needs less from the groundFreestanding matters on a bike trip more than on a hike: gravel bars, wooden platforms and hardpack are where you end up when you are following a road, and none of them take a stake.
Floor area
0.39m² more floor in the Hornet OSMO Ultralight 1PInner length by inner width as published. On a bike trip the floor also has to take whatever you brought inside off the bike, so a few centimetres is not nothing.
Peak height
27cm more headroom in the The OneWhether you can sit up, which decides how a rained-out afternoon goes.
