Enjoy comfortable fishing even in the strong summer sun!
Comfortable as if you weren’t wearing anything, and it stays in place! Shimano instructors rave, “This is great!” 【Cool Skin Arm Cover】 【OCEA Cool Skin Arm Cover】
The summer sun in Japan seems to be getting more intense every year. Fishing under such harsh sunlight can damage your skin, and you want to stay as cool as possible. That's where arm covers come in, but Shimano's 【OCEA Cool Skin Arm Cover】, released in 2025, offers a different wearing experience from previous models. Let's take a closer look at its performance.

Sunburn prevention makes your body feel much more comfortable
Due to global warming and climate change in Japan, summer heat is intensifying. During the day, the sun’s rays feel like they’re piercing the skin. Fishing in such conditions requires sunburn prevention. Neglecting this can lead to skin irritation and, in severe cases, burns. It can also cause sunspots, so caution is necessary. The simplest sun protection measure is sunscreen. However, sunscreen loses its effectiveness over time, so it is important to reapply it frequently. Another measure is to minimize skin exposure. While it may seem counterintuitive, using breathable or cooling materials can help. By preventing sunburn in this way, it is said that fatigue after fishing can be reduced. As a result, a style of layering breathable long-sleeve undershirts or innerwear with T-shirts has become popular recently. However, even with breathable or cooling materials, many people find wearing two layers too hot or less breathable. For such cases, we recommend arm covers that only cover the exposed parts of the arms when wearing a T-shirt.
Arm covers cover the area from the wrist to the upper arm. While various products are already available from different companies, some have drawbacks such as being too tight, slipping out of place, having thick fabric, or poor breathability. However, the “Cool Skin Arm Cover” to be released by Shimano in 2025 is different. It is praised by Shimano instructors for its comfortable fit.
A wearing sensation as if not wearing anything
So, what is the “Cool Skin Arm Cover”? First, it uses contact cooling material that feels cool upon contact with the skin. The material is thin, and by densely weaving ultra-fine yarn at the micron level, it achieves a soft, smooth texture. Additionally, the high-density weave and excellent stretchability allow for unrestricted movement while also preventing slippage. It is designed to eliminate the discomfort and stress caused by slipping, which is common in arm covers.

The fabric is soft and moderately stretchy, conforming to the body without feeling tight.
Additionally, the seams, which can sometimes feel uncomfortable when worn, are designed with M-stitching for a flat finish. It also offers UV protection with a UV blocking rate of 97.9%. It also has moisture-wicking and quick-drying properties, so it dries quickly even when sweaty, maintaining comfort.

Thanks to the M-stitching, the seams are barely noticeable. It offers exceptional fit.
Yamamoto Keito, an instructor specializing in jigging, calls it an indispensable item for summer fishing.
“Personally, I used to wear two layers—underwear and a T-shirt. While two layers can feel less breathable, I didn’t like wearing arm covers for sun protection because they felt tight and tended to shift. However, when I was given the ‘Cool Skin Arm Cover’ to try, I was blown away. It doesn’t slip, feels great on the skin, and doesn’t have a tight fit. Plus, it doesn’t get sticky even when you sweat. The seams don’t bother me either. It’s now an item I can’t live without.”

Yamamoto, who used to dislike arm covers, has come to love the Cool Skin Arm Cover. It stretches well, making it easy to put on. It can cover up to the front of the shoulder.
