Spidi 4Season H2Out 繊維のオートバイのジャケット

Great jacket, extremely comfortable, rode in 34deg today in Queensland Australia very humid & the jacket breathes well, I went one size larger than I normally wear & glad I did, fits very well with all layers in & adjustable enough to fit well with layers removed.

I bought this product about 2 weeks ago and crashed it one day later.
Styling:
The jacket looks great. If you care about looks just buy it.
Ventilation:
You can't get more air through, in any other jacket, unless you get the Dainese D explorer.
Warmth: with all the liners in and vents closed this makes for a good winter jacket if you wanted to. Also the Thermal layer could be used as a destination layer easily.

Protection: here's where it screws up. The back protector has no dedicated pocket. It sits based on 2 VELCRO strips and a bit of a half pocket in the upper part of the jacket. Major slip risk. The shoulder and elbow protectors as just level 1.
There is no zipper to tie it to your pants, just 2 straps you can wear trough your crotch which is weird to me.

As stated at the beginning i high-sided off the bike the second day after I bought it. Speed was somewhere between 40-50 kmh.
My shoulder got banged up quite badly and could only use it sparingly. The jacket didnt prevent the skin on my belly from being scuffed off a bit since i didn't use the straps which gave me a superficial open wound.

However, there was no skin damage on my shoulder which was the first part of me that landed. Additionally I did not break anything despite the pain.
The jacket sustained minimal damage and looks safe to wear again.
If you decide to go for this jacket a back-protector with its own strap would be better suited. Otherwise it is a nice choice of gear.

Very comfortable and the ventilation is second to none
Really like this jacket
