Product Overview
No need to overthink it — just grab 'em and glass. Triumph® HD binoculars strip it down to what matters, giving new users the confidence to pick apart the woods and spot game with ease. Fully multi-coated lenses deliver impressive images, and a rugged, no-nonsense design means you can focus on the moment, not second-guessing your gear.
The HD optical system uses select glass elements to deliver genuine resolution, cut chromatic aberration, and provide strong colour fidelity, edge-to-edge sharpness and light transmission for the price. A true open hinge design decreases total weight and bulk while offering superior ergonomics, and adjustable twist-up eyecups accommodate use with or without eyeglasses.
Built on a roof prism design for durability and compact size, the 10x28 is nitrogen gas purged and O-ring sealed for genuine waterproof, fogproof and shockproof performance — a dependable, grab-and-go binocular for travel, hiking and everyday outdoor use.
