"It's a little too hot for a jacket today."
On days like that, just throw this on over a T-shirt.
It looks like a work shirt.
But the moment you put your arms through the sleeves, you can feel it in the thickness of the fabric.
It's more than just a shirt.
It’s a garment designed with protection in mind.
Keep riding, even in the heat
It is made for continuous riding, even on hot days.
The vents on the sides and back let heat escape while you're moving.
Keep it on while you ride.
Take it off when you get off the bike.
It fits naturally into the flow of your bike and the city.
No distraction while moving
Points that might be bothersome while riding have been addressed in advance.
The collar won't flap around.
You can operate it even while wearing gloves.
The sleeves won't be too short even when leaning forward.
Adjustments to reduce unnecessary stress are firmly built in.
Not just gear, but a companion you'll keep using
Rather than "heavy-duty equipment," it feels like putting on a "reliable partner."
You want to hop on your bike without fuss,
but you don't want to compromise on safety.
This is the piece that will make your daily riding
more free and secure.
* While their names differ, the Trusty Shirt and Blackhawk Shirt are the same in function, with only their colors being different.
Why riders choose this shirt
Tough fabric that stands up to hard riding
Made with 12oz CORDURA stretch twill. It combines high abrasion resistance with stretchiness, allowing for comfortable wear without hindering your movement while riding.
Enhanced protection for your arms
The entire sleeve features a DuPont Kevlar lining, protecting your arms—which are prone to injury in a fall—from friction. It provides a reassuring sense of protection.
Cool and comfortable while riding
Equipped with SmartVent ventilation, it is designed to channel airflow through the underarms and back. It suppresses stuffiness even during long rides, keeping you comfortable.
Compatible with protectors
Designed to accommodate protectors for the shoulders, elbows, and back (*sold separately). It balances the lightness of a shirt with the protection required for riding.
Are looking for riding wear that works both for touring and in the city

Want simple styling but prioritize solid protection
Not recommended for those who:
Are looking for authentic jackets for high-speed touring or racing
Prefer a loose fit or an oversized look
Staff review
“When I actually put it on, the fabric feels solid, but the stretch makes it easy to move in, and I didn't feel constrained while riding. The fit is slightly slim, which prevents it from flapping in the wind, and it feels sleek.
It looks very simple, so it’s great that I can just wear it around town after getting off the bike. If you plan to layer it over a thick hoodie or the like, you might want to choose one size up. For touring from spring to summer, it’s a great alternative to a mesh jacket.”

~Please read before purchasing~
Do not assume "I'm always a size M, so I'll be fine."

How to measure

Lay it completely flat with the buttons fastened
Measure the "flat pit-to-pit width" (from side seam near the underarm to the opposite side seam). It is important to measure accurately to the seams on both sides
