Perfect in AStars Halo Drystar Jacket - L
Bought this in size Large to go in a size Large AStars Halo Drystar Jacket (I’m 6’ Tall, 145lbs, with a 6’7” wingspan, jacket has room to layer, arms are good).
Protector fits great, breathes well, can barely even tell it’s in there.
Also grabbed a size Large Nucleon KR cell CIR Chest Protector, same deal, fits great, breathes, and can barely tell it’s there.

Great protection and lightweight
Seems to be very light and breathable for the level of protection you get. Not super flexible but still comfortable. Thin, I wear it in my jacket and still wear a Ogio no drag mach5 overtop. I barely notice it there.

Remplacement facile vs mousse originale
On sent qu'il y a une protection plus rigide au lieu de la mousse originale mais je ne peux pas dire que je la sens dans mon manteau. Elle ne gène pas mes mouvements.

Low profile and excellent quality
Purchased a size L for my Halo jacket (also size L) fits great and hardly know it's there. 6' 190 pounds

Good stuff
I put it in my Alpinestars T-GP Plus R V3 Air. Good fit, easy to insert and good looking. I hope to never test it.

Perfect fit, comfortable and barely notice it!
Picked this up for a little extra protection, and once I put it in my jacket, I barely notice it's there. I have a 2xl Alpinestars crazy eight jacket and a L back protector fits it perfectly. Definitely worth the investment!

Bought to add safety on my jacket. Feels good and flows a lot of air. It has a bit of weight and a stiffness but still feels good having i

Trop rigide
Trop rigide pour moi. Semble offrir une très bonne protection mais manque de flexibilité bien s’adapter à mon dos. Mauvais fit, j’ai retourné le Nucleon.
