Another stunning item from the workwear industry
Perhaps new winds often come from outside
Kajimake , a workwear manufacturer based in Takaoka City, Toyama Prefecture, released ATION Crater Mesh , a high-cost-performance mesh underwear that can be used for outdoor activities, sports, and everyday wear , and now they have once again delivered an amazing item with a mind-blowing concept.
Rainwear hoods inevitably restrict your field of vision. What's more, if they're difficult to fit or let rain in easily, it can be frustrating..
There are times when you have to ride your bike even on rainy days, but it can be dangerous and you'll get wet, which can be depressing..
The PIRARUCU Rain Shaker solves all of these rainwear-related problems .
Wider field of view than any high-end rainwear
The hood of a typical rain jacket can be adjusted to fit your head size using drawstrings at the back of the head and at both ends. A well-made model will fit snugly, but even a well-fitting hood will inevitably feel a bit tight when you move your head, as the garment will twist
Furthermore, a larger brim increases waterproofing to prevent rain from blowing in, but the edge of the hood gets in the way and inevitably narrows the field of vision (see the photo below for an extreme example). This is a structural problem that almost all rainwear has

When you wear a hood and turn your head from side to side, your visibility is impaired, the hood may shift or come off, and it may feel tight, so you actually need to be very careful
The Rain Shaker solves these problems. I had never thought of it that way
The uniquely developed rotating hood, which uses patented technology, separates the hood from the body and connects them with a resin guide rail (see photo below), completely eliminating any twisting when you turn your head, allowing you to maintain the same wide field of view as when not wearing the hood, even when you turn your head from side to side. It also eliminates the feeling of tightness in your clothing when you move your neck, so you're always comfortable from the neck up. Of course, the connecting part is covered from above, so rain won't blow in from here

The hood, connected to guide rails, slides in response to neck movements, making it feel as though you're not wearing a hood at all
A problem for men who wear glasses: Rain, cycling, and glasses can still provide good visibility

Once I tried a rain visor, I found that it not only kept out the rain but also provided clear visibility, making it an indispensable item when cycling on rainy days
For people like me who normally wear glasses, it is inevitable that on rainy days the water droplets on our glasses make it difficult to see what is in front of us
However, this Rain Shaker comes standard with a removable rain visor patented by Kajimake, which virtually eliminates rain from blowing into your face from the front. Furthermore, the transparent material provides clearer visibility than regular caps, making it safer and more comfortable. Especially when cycling on rainy days, your glasses won't get wet even if you lean forward and look forward. Incidentally, this visor blocks 90% of UV rays
Stress-free three-dimensional cutting

Although it's not a particularly stretchy material, the well-cut pattern makes it comfortable to wear
The fit is neither too loose nor too slim, with a standard width. The carefully designed cut means you won't feel any tightness or riding up when bending or stretching your elbows or arms
A stylish design that can be worn on sunny days
It's obviously great for outdoor activities like camping and light hiking, but the subdued design and coloring with an elegant camo pattern (white, black, and brown), and the hood that can be stored in the stand-up collar make it a great jacket for everyday use, whether traveling or just hanging out around town

With its sophisticated design, it can be worn with a suit and used as rain gear for commuting to work
Details that will please outdoor enthusiasts and cyclists alike

a previous interview that the designer of this brand originally had a long and successful track record working for an outdoor brand , and this Rain Shaker also makes full use of the attention to detail he has cultivated through his work creating authentic outdoor gear.
The rotating hood features a drawcord at the back and Velcro at the chin, making it easy to adjust to any face, while providing both a wide field of vision and waterproof protection. The front zipper is a smart waterproof zipper. The sleeves also feature elastic and Velcro for a perfect fit. The hem also has a drawcord to prevent it from riding up
In addition, reflectors (reflective material) for safety in dark places are placed on the right hip and both ankles with use while cycling in mind (see photo below)

Reflectors are attached to the right hip and the side of the pants leg, so you can drive safely in dark places
The important waterproof and breathable performance is fine for everyday use. It's also decent for outdoor use

With a water resistance of 10,000 mg and breathability of 5,000 mg (nominal), it is fine for everyday use as well as light outdoor activities such as camping
As for waterproofing, the outer fabric is treated with DWR (water repellent) and the waterproof performance of 10,000mm is more than enough for outdoor use. The breathability is 5,000g/m2/24hr, which is lower than recent mountaineering models, but it should be fine for everyday to light outdoor use
Amazing cost performance with top and bottom set
This well-made top and bottom set is priced at less than 5,000 yen. As always, the workwear industry is truly impressive
This is what I'm curious about
Although I know that it cannot be compared to serious outdoor rainwear that costs tens of thousands of yen, there are still some things that concern me
What bothers me the most is that the mesh lining gets caught when putting your arms through the sleeves and tends to pop out from the inside. It's a bit frustrating. I'm sure the price will go up, but it would be interesting if this hood structure and three-layer fabric were designed to be suitable for serious outdoor use. Also, is it unavoidable that the hood hangs loosely at the back when left uncovered? If it could be secured a little more smartly even when the hood is out, I could enjoy two styles, a stand-up collar and an uncovered hood, on sunny days
Summary: The ultimate rainwear for everyday use, invented by a developer who knows the true essence of outdoor activities.
Pre-sales will begin on Wednesday, October 16th on Makuake (and with over 10% off!).
This rainwear was created by someone who truly understands the outdoors, thoroughly exploring the functionality needed for everyday use in the city, and has been given a new shape in a way that has never been seen before. The unique hood, which is surely one of a kind in the world, makes you realize just how restricting hoods have always been. I know it's impossible, but I hope Kajimake will create a full-fledged 3-layer rainwear for outdoor use with this mechanism
The PIRARUCU Rain Shaker is now available for pre-order at a discount on Makuake starting (I've also commented on it). There are also some high discount options available on a first-come, first-served basis, so don't miss out!

It's versatile enough to be used not only for everyday use but also for travel and hobbies, but it also cuts unnecessary costs and keeps the price within a reasonable range for everyday use. Its exquisitely well-balanced design will make you want to loosen your purse strings, so if you keep one in your entrance hall in addition to the full-fledged outdoor rainwear that is difficult to wear in the city, you may feel more at ease in your rainy daily life
