Salomon has introduced this year a new line of light and wide backcountry skis the “MTN Series” (which also includes a light touring boot and a new pin binding). I have not skied the Salomon MTN Explore 88 (2540g at 169cm), but reviews I found were very positive:
Test in Outdoor Guide (in German): Easy to ski, good in powder, stable, rather soft, also good on groomed slopes, highly recommended.
Test in Alpin Guides Blog (here): “It’s simply great fun to ski.”
The wider Salomon MTN Explore 95 (2800g at 177cm) also gets good reviews and has won the 2016 Editor’s Coice Skis 95-99mm of the Backcountry Magazine. The ALPIN Magazine found the Explore 95 to be suitable for powder, but generally rated the Explore 88 higher.
Salomon’s light MTN skis seems seem to perform great (and they are also a bit cheaper than other high performance backcountry skis). I have not skied them yet, unfortunately!
