Let me just start by saying: ORDER THESE.
I’ve worn and broken or lost just about every brand of sunglasses there are. Whether I’m splitboarding, mountain biking, river rafting or on my way to the beach, I seem to have a different pair for each. Most often, the arms break off or I set them down somewhere and never can remember where.
Ombraz solved for both issues by removing the arms and adding the strap. Initially, I was concerned I wouldn’t be able to wear them with a hat or helmet, but I soon found them easy to adjust and perfectly comfortable. The Dolomites even have side shades that function well enough for glacier travel. When I reach the top of the skin track or end of the trail, I just throw them in my pack and never worry about pulling them out broken.
I’ve had the same pair for about two years now and take them everywhere I go. Really couldn’t recommend them enough.
