Gear Review | Auftriib Saucer

Game changer for ascents in steep gullies

by Carla Brandt 11/20/2023
Anyone who has ever walked up behind someone who has used Auftriib can hardly do without these "gamechangers". What am I talking about? Polypropylene plates that you strap under your ski boots (in conjunction with crampons) to move forwards or upwards in couloirs or any kind of deep snow. As the name suggests, they give you buoyancy and make your bootpack a lot easier in deep snow.

You won't get up there without sweating and working hard, but two plates on your feet can make your life so much easier!

The first impression

For the test in northern Norway (Tromsø), I choose the Saucer version of Auftriib as a climbing aid. It is known as the "Powder Adaptor" for crampons and (like all Auftriib products) is made of thermoplastic. They are therefore add-ons for your ski boots with crampons. The plates come in a jute bag and instruction manual, which explains the functions and application again.
The saucers have a front recess for the front points of the crampons and a rear hole for the rear points. Two Dyneema loops on both long sides are connected by a ski strap made of a stable rubber compound. This attaches the ski boot and mounted crampons to the Saucer. The first impression is therefore visually appealing, carbon look despite thermoplastic, light, pressure-resistant and minimalist in design. Not a lot of bells and whistles - after all, they are supposed to be easy to fit and help where you would otherwise get almost nowhere: in steep (sometimes exposed), deep snowy terrain.
The weight of the pair in size S including ski straps and Dyneema straps, measured on our own scales, comes to exactly 400g.
The pack size is so practical that I actually don't even think about not taking them with me all winter in Norway. You never know what to expect, whether you might find a couloir somewhere in the valley. Firmly stowed away in the back of the backpack, where many manufacturers usually provide "bladder storage", they are simply always with you. You have to admit, however, that I have a smaller pack size due to the size S I chose (sole length: 275-300mm). Measured 31cm long and 25cm wide.

The tester

I'm 1.80m tall, weigh 70kg with equipment (with skis on my back I can easily weigh 75kg) and have an extremely small footprint with size 38 boots or Mondopoint 24. This generally means that I don't have much "buoyancy" anatomically when I take off the big skis and strap them on my back.
Most of the time, someone broke the trail ahead in the boot pack - and even then I had my difficulties, despite being in pretty good basic condition. It wasn't unusual for me to sink deeper than the track that had already been laid and I struggled to make progress.
Now I've been living in Norway since the winter of 2022, and the gutter game takes on yet another dimension. To be honest: you almost always try to find a gully somewhere. Be it because of visibility, because of wind-protected snow or because of darkness - you have such a great spotlight effect when you're hurtling down in the dark and the walls give you "safety".
In terms of skiing, I like to push myself to my limits, but I often choose to turn back, because coming home healthy and happy is at least as nice as having powder on your face.

The test report

The saucers are used a lot during March and April. When putting them on, you should make sure that there is a narrower side and a wider side. So there is a right and a left plate. Choose the narrow side so that it is on the inside of your foot. This narrows the width of your crotch.
I walk quite upright in the bootpack, have the skis strapped to the triangle on both sides of the pack and therefore have a good vertical vector. I take one pole shorter than on a normal ascent and the ice axe in the other hand for safety. For the "crawlers" among us, i.e. those who like to have all fours in contact with the snow, support the poles parallel in front of them in the snow and therefore generally have a lower centre of gravity: this technique should also work, see Merrick Mordal and co. Personally, I find it more comfortable to have the plates working underneath me rather than behind me.
If there are small climbing sections in the couloir, you can simply leave the saucer on. The front spikes are free at all times. You should just make sure that you always place your foot with the front points facing the mountain. To be more precise (and this also applies to the normal bootpack): You shouldn't put your weight on the foot that is placed sideways. These things are suitable for walking straight uphill and NOT for traversing. If you are traversing, keep your face to the mountain and put your foot next to your foot - otherwise your crampons will have no snow to grip under the plates.
I use my Blue Ice Harfang Crampons as test crampons, which are advertised as compatible (see list below for compatibilities). Initially, I still find it difficult to mount the crampons in steep terrain, but that changes just as quickly as you get used to putting on crampons.
We sometimes do two couloirs a day and I track ahead. That's never been the case before. The energy saving is actually huge and I have a lot more energy left in my thighs for the descent.
I still work up a sweat and the feeling of "scrambling up" remains, especially in steep terrain. The Saucer also doesn't change the fact that you have to push your knee forwards from 45° to maintain the right angle for stability. Nevertheless, everything is just a little smoother. Another plus point is that when going uphill, the risk of getting your crampons caught in the snow guard of the expensive Goretex trousers is minimised to almost zero. The width of the plates (25cm for size S as written) forces you to walk with your legs a little wider than you would without the plates. This is not annoying and I am grateful to have avoided the Goretex repair this season.

The bottom line

The Saucer is an integral part of my backpack. 
Extremely high benefit with easy use, light weight and as a reward more power on the descent.
The price makes you swallow and think twice (there are also people who try to replicate this - so far I have not been able to find a comparison that works equally easily and safely). The company with founder Andreas Trunz is from the Säntis region, has its production in Zurich by the Swiss company Cem Koeylueer and is unique in its field. A real pioneering achievement, which has come onto the market through the collaboration of ski pros such as Cody Townsend, Sam Anthamatten and Andreas, initially in his spare time, private investment and the support of his own family. Andreas produces all the products himself. Cem had made the prototypes from carbon, now he presses the boards himself in Zurich.
In my eyes, absolutely worthwhile - it's not for nothing that Nikolai Schirmer says: "Probably the best thing that has happened to backcountry skiing since the double rocker skis".

Perfect for you, if:

  • Your crampons are constant companions on your ski tours 

  • You are planning technical lines with long bootpacks and/or rocky passages

  • You want to save your leg strength for the descent/ski mountaineering 

The details

RRP €183,-

Dimensions     35 × 25 × 3 cm

Size    S, M, L (S: 275-300mm / M: 295-320mm / L: 305-330mm)

Weight in g per pair (according to manufacturer) 394, 424, 438 (measured in size S - 400g)

Material: High-end fibre-reinforced polypropylene, 100% recyclable. It is a fibre composite material from Germany that looks like carbon, but is more impact-resistant, less energy-intensive and recyclable.
TIP: It is possible to make small adjustments to the material to adapt it to other types of crampons. For example, the "nose" can be shortened by 1-2cm using a conventional wood or metal cutting tool. Edges can be rounded with sandpaper or a file.

Until now the Saucer was used with the following crampon models :

  • Edelrid Shark Lite

  • Petzl Leopard LLF / FL

  • Petzl Irvis (Hybrid)

  • Petzl Sarken

  • Petzl Vasak

  • Grivel Air Tech New-matic

  • Blue Ice Harfang

Here is the website of Auftriib with further information. There is also a very interesting product guide.

The Saucer was provided to PowderGuide by Auftriib free of charge for testing. You can find out how we test it in our test statement.
