NEMO Hornet OSMO Ultralight 1P — shelter drawn to scale. Inner floor 220 by 99 cm. Packed poles 32 cm, inferred from packed length: fits across a 40 cm drop bar.
NEMO Hornet OSMO Ultralight 1P, drawn from the maker's published figures. Inner floor 220 × 99 cm, with a 183 cm sleeper drawn in for scale. The packed poles are 32 cm, inferred from the packed bag rather than published by the maker.

Will it go on your bars?

The folded pole set is 320mm, which is the 15th shortest of the 29 shelters we hold a pole length for. At 822g it is 9th lightest of 37.

On the two weights. The 879g at the top of this page is the figure we hold on the product record. NEMO also publish a minimum (trail) weight of 822g and a packed weight of 1000g. Minimum weight leaves out stakes, guys and the stuff sack; packed weight is everything in the bag. We show all three rather than picking one and calling it “the” weight.

On drop bars
320mm poles — fits drop bars

Comfortably inside the usable span on drop bars, with room for cables and a harness. This figure is the packed bag's long dimension, not a pole length the maker publishes — for this style of tent the two are the same thing, but measure before you commit.

On flat bars
320mm poles — fits flat bars

Comfortably inside the usable span on flat bars, with room for cables and a harness. This figure is the packed bag's long dimension, not a pole length the maker publishes — for this style of tent the two are the same thing, but measure before you commit.

One shelter here is both shorter-poled and lighter: Nordisk Lofoten 1 ULW (220mm, 490g). Anything not on that list is a trade rather than a straight win.

Only 29 of the 43 shelters we track publish a figure we can compare, which is why this question is so hard to answer anywhere else. The figure above is the packed bag's long dimension rather than a pole length the maker publishes — for this style of tent the two are the same thing, but measure before you commit.

NEMO Hornet OSMO Ultralight 1P — Specs & Analysis

Manufacturer specifications, compared against every other shelters & tents in our database. We do not test gear in the field — we measure, verify, and compare.

The Hornet uses Nemo's OSMO fabric which doesn't stretch when wet like traditional nylon. This means consistent pitch in rain without the saggy-tent syndrome. At 879g, it's one of the lightest full-featured solo tents available.

Who Is the NEMO Hornet OSMO Ultralight 1P Best For?

Riders who camp in wet conditions and want consistent tent performance. If that describes your riding style, the Hornet OSMO Ultralight 1P should be at the top of your shortlist. It sits in the Shelters & Tents category alongside 17 other products we track.

How It Compares

At 879g and $370, the Hornet OSMO Ultralight 1P is 729g heavier than the lightest option in this category (the Borah Gear Cuben Fiber Tarp at 150g). The most budget-friendly option is the MSR Thru-Hiker Mesh House 1 at $150.

The price-to-weight ratio comes in at $42 per 100g — a premium price point, but you're paying for quality, materials, and design that justify the investment for serious bikepackers.

What We Like

  • +OSMO fabric stays taut when wet
  • +879g is class-leading light
  • +Excellent ventilation design
  • +Jake's foot design for quick setup

Watch Out For

  • Tight for larger riders
  • Single vestibule limits gear storage
  • Stuff sack is tiny and hard to repack

The Bottom Line

We haven't scored the NEMO Hornet OSMO Ultralight 1P, and neither has anyone else we can cite. It's here for its verified specifications and dimensions, which is what the fit tools run on — a score is an editorial judgement, and we don't hand one out until someone has a basis for it. What this page can tell you is measured: 879g, $370, and how both sit against every other shelters & tents product we track.

The price and weight above have not yet been checked against the manufacturer's own page. We are working through the catalogue and saying so as we go, rather than letting silence imply otherwise.

Specifications and dimensions come from the sources listed above. Where a page draws on first-hand riding, it says so.

What it packs down to

NEMO publishes a packed size of 5" x 19", which is 6.1 litres as a stuff sack. Of the 55 bags we track that publish a capacity, 28 have room for it and 27 do not.

Volume is computed from NEMO's own packed size, treating a two-dimension figure as a stuff sack. Bag capacities are the makers' published figures, not ours — 12 of the bags we hold dimensions for publish no capacity and are left out of the count rather than assumed. A stuff sack does not reshape itself, so read the headroom as room to spare rather than a guarantee it goes in easily.

How the Hornet OSMO Ultralight 1P compares

Against the bags people cross-shop it with, measured rather than reviewed — including how many real frames each one fits.

Weight and price come from published specifications. Cost per 100g is a blunt measure — it rewards light gear and says nothing about durability or whether the thing works — so treat it as one input, not a verdict.
