NEMO Hornet OSMO Ultralight 1P vs Six Moon Designs Lunar Solo

Two shelters, measured against each other on the figures that decide whether they work on a bike.

The short answer

The Hornet OSMO Ultralight 1P takes pitching on hard ground; the Lunar Solo takes weight, floor space, headroom and price. 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 Lunar Solo has no pole set at all, the Hornet OSMO Ultralight 1P does

None — trekking-pole shelter

A 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

82g lighter on the Lunar Solo

822g
Six Moon Designs Lunar Solo
740g

Trail 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, Lunar Solo is single

single wall

A 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

Needs stakes

Freestanding 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

0.58m² more floor in the Lunar Solo

220 × 99cm — 2.18m²
Six Moon Designs Lunar Solo
228 × 121cm — 2.76m²

Inner 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 Lunar Solo

Whether you can sit up, which decides how a rained-out afternoon goes.
