Product Information
Full details
The Troy Lee Designs 3900 Upper Protection Vest is designed for adult mountain bikers and motorsports enthusiasts seeking high-level core protection without the bulk of a full jacket. Leveraging Shock Doctor technology, this vest provides robust impact defense for the chest, ribs, and spine while maintaining excellent ventilation for warm-weather riding. While it offers industry-leading safety and neck brace compatibility, riders should note that it provides coverage primarily for the torso, leaving the arms exposed to minor scrapes.

FAQs
Is this vest machine washable?
It is recommended to remove the foam padding and hand wash the vest to ensure the fabric and elastic components retain their shape.
Can I wear this under a regular jersey?
Yes, the anatomical, slim-profile design is specifically meant to be worn under a jersey or base layer.
Does this provide shoulder protection?
No, the 3900 model is designed specifically for chest, rib, and spine protection.
Is it compatible with all neck braces?
It is designed to be compatible with most leading neck braces, though fitment may vary depending on the specific model of your brace.
What is the primary benefit of Vent-Track technology?
It uses flexible channels to pull air over the skin, which significantly reduces overheating compared to solid foam armor.
Troubleshooting
Vest feels too loose during active riding
Ensure the side straps are tightened appropriately and confirm you are wearing the correct size for your chest circumference.
Neck brace interferes with the chest plate
Adjust the front plate positioning of your neck brace to ensure it rests correctly on the designated reinforced area of the vest.

Setup, Compatibility & Care
To achieve the best fit, ensure the vest is snug against your torso without restricting your breathing. If you are using a neck brace, attach it according to the manufacturer's instructions before zipping the vest fully. For maintenance, always remove the internal vented foam pads before washing the textile carrier. The vest should be hand-washed in cool water with mild soap and air-dried away from direct sunlight to preserve the integrity of the protective materials.
