FOX BASEFRAME PRO SL BACK PROTECTOR

The Fox Baseframe Pro SL Back Protector is a protective MTB base layer that puts the focus on the back with the smallest possible footprint. With its D3O® Viper back insert certified to EN1621-1 level 1, it delivers serious protection for enduro, trail and bike park while staying thin, close-fitting and easy to wear under a jersey.

The D3O® insert is the real star: the polymer softens with body heat and conforms to the shape of the back, then stiffens on impact to absorb the energy of the hit. The certification also covers high and low temperature conditions, so protection stays reliable from summer to deep winter. Large perforations and flex grooves let the foam follow the rider's movements, while the open stretch mesh manages moisture and lets air circulate.

Back protection and materials of the Baseframe Pro SL

• D3O® Viper back insert, CE certified to EN1621-1 level 1, including high and low temperatures
• Foam with large perforations and flex grooves that follows the body in motion
• Polymer that softens with body heat for a custom fit
• Open stretch mesh that wicks sweat and improves breathability

Unlike a full chest protector, the Baseframe Pro SL concentrates protection on the back and leaves the chest free, a setup appreciated by riders who pedal a lot and want ventilation. It is worn like a normal close-fitting base layer, with your favourite jersey and, if needed, a backpack on top: the protection stays in place and does not get in the way of your riding position or movements on technical sections.

Why choose Fox Baseframe Pro SL

• Minimal restrictions, maximum benefits: back protection without the feeling of wearing armour
• Built-in hip padding for extra comfort
• Removable D3O® Viper insert for easy washing

It is the ideal base for building your protection kit: riders who pedal a lot and descend fast get back protection they can wear all day, without having to choose between safety and freedom of movement. For those who want to protect their back without giving up lightness and ventilation, the Fox Baseframe Pro SL Back Protector is the practical choice for every ride.
