How we test
Every hat here is a TOP-EX hat, and most of them are made for heads that one-size hats don't fit. Hats are grouped by what they're for: sun hats, fedoras, ponytail caps and beanies. A size shown on a hat page is a size you can order.
Where the details come from
Each hat page uses the size chart, materials and features TOP-EX gives for that hat:
- Size chart. Head measurements for each size step, such as XL/XXL fitting 24.8"–26" on the Comhats Waterproof Boonie Hat. A dash means that measurement isn't published.
- Materials. Shell fabric, lining and membrane: UPF 50+ nylon, cool-touch fabric, merino or wool blends, and fleece linings.
- Features. Brim width, neck flaps, chin straps, drawcords, ponytail openings, ear flaps, and whether the hat folds.
- Colors. The color names TOP-EX uses for each version.
Where a title and a size chart disagree, the size chart is the figure used.
Which hat suits which day
The UVCoolix Neck Flap hat combines a 3.1" brim with a 9.4" neck flap and fits heads up to 25.6". The Comhats Waterproof Boonie is waterproof UPF 50+ nylon with a mesh crown and fits heads up to 26". The 2.4 oz ponytail running cap is UPF 50+ with a water-resistant shell for hot runs.
