Canon 10×42 L IS WP
This 5.4 x 6.9 x 3.4-inch pair of binoculars weighs more than most competitors at 39.2 ounces, but is worth considering. They are the smallest binoculars on the market that offer both image stabilization and a full waterproof rating. Image stabilization isn’t cheap (check the price, ouch), but it’s super cool.
