Great product
It’s a back protector - fits easily and does the job. 10/10
Perfect fit into my alpinestars bogota jacket. It's really comfortable and flexible for a level 2 protector.
Good bit of kit that comfortable
The Alpinestars Nucleon Plasma Back Protector is incredibly comfortable and offers excellent protection without feeling bulky. It fits perfectly under my jacket and moves naturally with my body, making it easy to wear even on long rides. For the quality and safety it provides, it’s a fantastic value. Highly recommended for any rider looking for top-tier comfort and peace of mind!
Good item
Fits perfectly in my jacket. Good quality
Perfect fit , feels like its hardly there
This is definitely made from good material and feels like it could withstand the impact. It's flexible enough to get used to it and slots in perfectly with all 3 of my alphinestars jackets.
Fitted jacket well and quickly. Comfortable to wear did not know it was there
Hi quality very comfortable back protection that doesn’t make you hot and sweaty, moulds nicely to your shape and fits perfectly in my Alpinestars hoodie.
Great service from sportsbikeshop as ever.
Love this fits perfectly in my alpinestar chrome hoody bit pricey but really good quality item
Slim and flexible
I brought this after realising it is an optional extra with the Alpine star jacket I bought
Fits nicely in jacket and when out riding it is very comfortable and you don't get hot and sweaty with it
Fast delivery
It feels well made and gives me that peace of mind fits well into alpinestars jacket.
As the title, when this warms up (which doesn't take long) it moves and moulds to you. The old armour was so thin and light you never felt it after 5 min, this becomes part of you.
Was considering between the short and long and the short is more than enough for street riding.
SBS fantastic ordering me in the right size and making sure it fits. Which was a size medium (I am 5'10") for a size 54 Atem Jacket.
Bought to compliment a TechAir3. Like for like size (medium vest and medium back protector). Could probably fit a large back protector in, as there is a Velcro tab to accommodate longer items. Soft enough to be comfortable. Hope I never need it.
Great service & delivery, exceeding my expections. Split delivery of multiple items but everything arrived ahead of schedule.. Really pleased.
