Nordisk Lofoten 1 ULW vs Outdoor Research Helium Bivy

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

The short answer

The Lofoten 1 ULW takes pole length, floor space and vestibule space; the Helium Bivy takes 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.

5 of the 7 things we can measure come out differently.

220mm — fits drop bars
Outdoor Research Helium Bivy
311mm — fits drop bars

The length of the pole set broken down, which is what decides whether it goes across your bars. Almost no maker publishes it, which is why this comparison is hard to find anywhere else. The verdict beside each is for drop bars.

double wall

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.

Floor area

0.39m² more floor in the Lofoten 1 ULW

220 × 85cm — 1.87m²
Outdoor Research Helium Bivy
208 × 71cm — 1.48m²

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.
