The Mehlsack is known for its enormously long north face, which is also popular among heliskiers. The Mehlsack and the Schneetäli are the last two drop-off points for heliskiing, which somewhat spoils the idyll on good touring days.
Anyone wanting to do this tour should start as early as possible so that helicopter tourists haven't already taken everything. Usually, helicopters don't start before 10:00 a.m. Ambitious ski tourers are ideally already on the summit before that.
If you are in good shape, you can start the tour through the Stierloch to the Stierlochjoch and then enter the route. You don't have to wait for the first ascent of the Madlochbahn, and you are thus definitely ahead of the air traffic at the summit.

Safety information
Beware of numerous terrain traps in the upper part of the bowl near the summit.
The large north slope in the middle section is regularly controlled and skied. However, it is also a textbook avalanche slope and should be skied with caution. The catchment area is enormous, thus providing potential for large avalanches.
Tips and suggestions
Roadbook
From the top station of the Madlochbahn, you follow the "Stierloch" variant along the route to the Stierlochjoch. This is where you put on the skins. The first 250 meters of elevation lead up the steep eastern flank until the terrain becomes flatter. From there, continue northwest until you reach the distinctive saddle. From there, you face the impressive summit bowl, which you traverse in a wide left curve and thus reach the summit through moderately steep terrain.
The descent can be extended in the sense of the ascent, or under good conditions, you can take a more direct route into the bowl. However, the bowl contains numerous terrain traps, gullies, and hollows that must be cautiously assessed. Eventually, you reach a fairly steep section at the northern end of the bowl, which you skillfully pass and then enter the very wide and long main slope. From here, you descend in wide, large turns until you reach the forest road. From there, follow the road always downstream along the Zugerberg chairlift and back into the ski area.
