Celestron's Noble series offers high-level roof prism optics and a competitive price. They are rubber armored and nitrogen purged for waterproof operation without the risk of internal fogging.
The 10x28 model is a go-anywhere high-powered pocket pack, providing excellent views when the light is good.
They also have 15mm of eye relief, which is quite good for compact roof prism binoculars.
