TomShop-US via Amazon offers the Tomshoo 180° Full-Face Snorkel Mask in several colors (Black pictured) from $35.35. Coupon code "DDGY4296" takes an extra 34% off, dropping starting prices to $23.33 (and no higher than $25.66). With free shipping, that's the lowest price we could find by as much as $21, although we saw select options for $2 less last month. Features include anti-fog and anti-leak technology, a flexible piston design, waterproof earplugs, and adjustable fabric straps. It's available in sizes S/M and L/XL. Deal ends November 30.

Note: Although the product title mentions an "action camera mount," only select color options have this feature. (It's noted in the color name.) Don't need it soon? Select options are less at TomTop, where all colors are $24.99 with free shipping. However, it ships from China and may take up to four weeks to arrive.
