Klättermusen · Ull Backpack 20L

Ull 20L: a day on skins, closed with one hand.

The Ull 20L closes with a drawcord, keeps avalanche tools in an inner pocket and carries skis, poles and ice axe on the outside. A side zip gets you into the pack without opening everything. Light, narrow, made to move.

Ski touring · Mountaineering · Hiking

The day's skin track, the fast ridge, the summer mountain hike.

The name likely comes from Ullr, god of snow, the bow and skis. From the Edda.

Take it if the down jacket, lunch or a night in a hut come along: a pocket on the hip belt, and the ice axe within reach without taking the pack off.

See the Ull 30L

Same 47 to 52 cm back, same fabric, same drawcord opening, same inner pocket for avalanche tools. The 30 L adds a hip belt pocket and an ice axe carry you can reach with the pack on; the 20 L keeps the side zip.

On your back

A back panel that comes out and doubles as a sleeping mat.

  1. Four-point sternum strap (4-S System®)One fixed side and one elastic side: the pressure spreads across your chest, the pack stays glued to your back on the descent.
  2. Rigid foam frame sheetIt keeps the load in shape, comes out to save weight, and can serve as a bivouac mat.
  3. Hip belt with safety buckleA metal buckle that does not open by accident, and a webbing loop for clipping on small gear.

In motion

The Ull in the mountains, 14 seconds.

In the rain · over 10,000 mm

The fabric holds wet snow and proper rain.

Lightly water repellent

300 mm

Drizzle, or brushing past wet branches.

Shower

1,500 mm

A shower on the trail or in town.

Waterproof fabric

10,000 mm and above

Proper rain: the fabric holds, the seams are not taped.

Waterproof

taped seams

Rated waterproof: seams covered with tape.

Wet snow and proper rain, yes. The drawcord opening lets water in over time: in rain that lasts hours, the down jacket goes in a dry bag.

Will it fit me?

47 to 52 cm

back length

Measure your back before you choose.

  1. Measure your back from the 7th cervical vertebra (the bump at the base of your neck) to the top of your hips, along the spine. Compare with the range above.
  2. Too short or too long? You have 30 days to send it back.

What clips onto it

One more pocket, same bag.

Repair rather than replace

Klättermusen repairs zips, seams and buckles. Outside the guarantee the service is paid, on quotation; Eiken passes the request on.

Care

Empty it and let it dry after the outing, hand wash with a mild soap, reproof if needed.

Eiken's take

Our pick
A ski touring pack with no frills: a drawcord to close it, straps for skis, poles and ice axe, and the avalanche tools kept apart, inside.
Worth knowing
718 g, where a Gilling 20L weighs 560: the frame sheet and the attachments have a cost. And 20 litres fill up fast in winter, between the shovel, the probe and the down jacket.
Who it's for
Day ski tourers and mountaineers who move fast, with a 47 to 52 cm back.

Baptiste, Eiken

Questions

What about rain?

Proper rain, yes: the fabric holds over 10,000 mm of water. The seams are not taped: in a storm, a rain cover still helps.

Does it carry skis?

Yes: the skis attach to the sides of the pack, the poles and the ice axe to the outer straps.

Shovel and probe?

An inner pocket is set aside for them, apart from the rest; it also takes small gear. It is not an airbag pack.

Which back length?

47 to 52 cm, regular cut. The frame sheet comes out; if in doubt, you have 30 days to try it at home, loaded.

Care

Hand wash with a mild soap. No bleach, no tumble dryer, no iron, no dry cleaning.
