[Editor’s Note: Our “First Looks” are our way of getting you information sooner on some of the products we’re reviewing, including our measured specs and the details from the manufacturer. Once we’ve started testing a given product, we detail our on-snow impressions in our Flash Reviews and our annual Winter Buyer’s Guide. When we’re able to spend extensive time testing a given product, we publish our in-depth Full Reviews and Deep Dive comparisons.]
What Romp says about the Oso 105:
“Decisive Executive for the Rugged Unknown.
Inspired by the vaunted technical terrain of Crested Butte’s North Face. Romp has built the Oso line to be smooth and unfazeable in steep, variable, and unpredictable zones. The longer turn radius makes these skis very confident at high speed but remain quick and nimble in complicated terrain. The skis of the Oso line provide you with stability and control to give you confidence when the terrain gets hairy! Find your line on a Romp Oso!
- Strong, stable, and nimble, we designed the Oso 105 to navigate Crested Butte’s vaunted North Face.
- A versatile platform & rocker profile will excel on Powder, Piste, and everything in between.
- Ski where you want and when you want on the Oso 105.”
