For the past 90 days, I've been putting the Oeppeo Daiwa Cap—specifically the Sun Protection Fishing Cap model—through its paces. This review provides a day-by-day breakdown of my experience, focusing on real-world performance and long-term value to help you decide if it's a smart purchase.
Before buying, my main criteria were a cap that could withstand long days outside. Sun protection and breathability were my top priorities, along with adjustability and durability, since cheaper caps often don't last.
This review walks you through everything from the initial unboxing to how the cap held up after three months of regular use. I'll also share a few pleasant surprises I discovered along the way.

The cap arrived in a simple plastic bag—nothing special. My first impression was how surprisingly lightweight the material felt. It seemed almost too thin at first, which made me question its durability. The stitching looked decent upon inspection, and the adjustable strap in the back was straightforward to use. As one of the large baseball caps I ordered, it matched the product description.
One slight letdown was the lack of extra features. I've seen other fishing hats with neck flaps or hidden pockets, but this one keeps things basic. If this model doesn't suit your needs, the Oeppeo store offers a good variety of other hats worth browsing.
Verdict: My initial impressions were mixed. The lightweight feel was both a pro and a con—I needed to test it over time to see how it would really perform.
During the first week, I wore the cap while hiking and gardening. The breathability was noticeably better than my old cotton cap—I stayed less sweaty even in direct sun. The large size provided ample shade for my face and neck.
That said, the cap's shape took some getting used to. It's more structured than others I've owned, so it felt a bit stiff initially. I adjusted the strap a few times before finding the perfect fit.
Here are a few adjustments I made early on:
Verdict: Breathability is a big win. The fit requires a little fine-tuning, but once adjusted, it's quite comfortable.
