Friday night at the first hut, Sunday night back at the car.


On your back
A frame for a full pack, a back that breathes.
- FrameA foam back panel rimmed with spring steel wire: it holds the pack's shape when it's full.
- Suspended backBreathable mesh on the panel and under the shoulder straps: air moves between your back and the pack.
- Hip belt with pocketsTwo pockets on the hip belt for the small things; the hydration tube exits on the left or right.


Will it fit?
41 to 48 cm
size M, the only size sold at Eiken
The back length isn't adjustable: the Terravia Pack comes in S, M and L, and Eiken sells size M. With a shorter or longer back, the hip belt sits below your hips or rides up onto your stomach.
A fixed back, cut in M: measure yours.
Measure your back from your C7 vertebra (the bony bump at the base of your neck) down your spine to the top of your hip bones, and compare with the length shown.
Too short or too long? You have 30 days to send it back.

What fits inside
36L
Two nights in huts, and a roll top that follows the load.
The top rolls down: unrolled, it takes extra gear; for a light load, you roll it lower and cinch it. On the front, an open pocket keeps an extra layer within easy reach.
- Two nights, hut to hut
- A jacket in the front pocket
- Two bottles and a hydration reservoir


Colours
Black, or a grey-green you can spot on the trail.
Black
Black from fabric to straps, only the blue label stands out: it blends in with any hiking kit.
Blue Sage
A pale grey-green, khaki straps and zip pulls: easy to spot from a distance on a scree slope, without shouting about it.

In the rain
Two days on foot, a shower: the cover is waiting in the base.
Light rain
Water-repellent fabric
PU coating and a durable water repellent (DWR) finish: water beads up, then eventually gets through at the seams and zips.
Shower
Laminated fabric
Fabric covered with a TPU film (a flexible plastic) that stands up to the weather. The seams aren't taped.
Proper rain
Rain cover
A removable cover goes over the whole bag. Without it, the coated fabric eventually lets water through.
This bag
Get the cover out before the shower hits: packed away in its pocket, it protects nothing.

Eiken's take
- Why we chose it
- A frame, a hip belt with pockets, a roll top and a rain cover included, for 1,066 g: what you need for two nights in huts, and no more.
- Worth knowing
- 36 litres is the size for huts, where a bed and a meal are waiting for you: there's no room for a tent, sleeping bag and stove to camp self-sufficiently.
- Who it's for
- Hikers who string together two nights in huts, or go fast and light on a long day.
Baptiste, Eiken

Questions
What are the dimensions and weight of the Terravia 36L?
65 × 30 × 23 cm for 1,066 g, in size M: the largest of the Terravia Packs.
Is the Terravia 36L waterproof?
With its rain cover, included and stowed underneath, it handles proper rain. Without it, the coated fabric lets water through in the end; it still isn't waterproof.
How many nights can I go out with it?
Two nights hut to hut, where a bed and a meal are waiting for you: the roll top takes the extra. To camp with a tent, sleeping bag and stove, 36 litres is too tight.
What does the frame do?
It holds the pack's shape when it's full: a foam panel rimmed with spring steel. The Terravia 14L, 22L and 28L don't have one.
