Protection vest Alpinestars Bionic Tech V3: Why is it one of the best?

For enduro and motocross riders who place safety at the top of their priorities, the choice of a protective vest is crucial. Alpinestars, leader in the sector, offers with its Bionic Tech V3 a solution designed for those who do not want to compromise. Announced as the most protective vest in the Alpinestars range, we have analysed it in detail for you.

Maximum protection: Full CE level 2 approval for this vest

The characteristic that immediately distinguishes the Alpinestars Bionic Tech V3 vest from the competition is its level of certification. While many vests combine Level 1 and Level 2 protections, the V3 offers a EC Level 2 homologation on all its main hulls :

• Chest
• Back
• Shoulders
• Elbows

This certification ensures maximum shock absorption capacity, which is rarely seen on such a comprehensive set. In addition, the breastplate does not simply cover the chest; it extends over the flanks to provide a enveloping protection of the coasts, a major asset in the event of a lateral fall.

The Alpinestars Bionic Tech V3 vest has a built-in abdominal strap with kidney protection, which makes it easier to keep the vest in position, making it safer and more secure in the event of a fall.

Design and Modularity: A two-part system

One of the smartest features of the V3 is its modular design in two distinct parts:

1. A technical underwear (basic layer): Ultra-breathable and elastic, it incorporates shoulder and elbow protection.
2. The protective plastron: type stonewall, it includes the front plastron and the backbone, connected by adjustable straps.

This separation offers remarkable versatility. You can choose to wear only the backbone with the plastron (like a stone guard) over or under the jersey, or wear the complete set for maximum protection. This also greatly facilitates the washing of the vest.

Key Technologies and Materials

To reconcile a high level of protection with a contained weight and good ventilation, Alpinestars uses its Polyhedron Technology for chest and back shells. This lattice structure, inspired by the very light Alpinestars stonewalls A1 Pro, provides excellent shock absorption while allowing air to circulate freely. The V3 is therefore surprisingly light for the level of coverage it offers.

The technical underwear is made from a very airy mesh fabric. It should be noted that the meshes are particularly wide under the arms and on the sides of the torso, maximising the evacuation of heat. The ventilation of this basic fabric seems superior to that of the other vests of the brand such as the Bionic XTR or V3 Plasma.

Adjustment, comfort and user feedback

Size and adjustment:
The vest size is quite standard. For example, pilots of around 1m70 to 1m75 for 75-80 kg will feel comfortable in a size L. Multiple adjustment straps (on the shoulders and sides) allow the vest to be precisely adjusted to the pilot’s body.

Points to consider:
During the tests, a few potential friction points were noted:

• Light pinch: Some users noted a slight gene on the flanks, at the lower part of the back protection, in a sitting position.  This is a point that was not felt with the Alpinestars models XTR or Plasma, but it should be noted that their back protectors are less wide and covering.
• Fitted cut on the forearms: The underwear can be quite tight in the forearms for the most muscular pilots.

How does it compare to other Alpinestars models?

To make a better choice, it is useful to position the Bionic Tech V3 in the range:

Bionic Tech V3 vs. A-1 Pro : TheAlpinestars A-1 Pro is a pure stonewall, designed to be as light as possible while being certified. The V3 uses its Polyhedron technology but for a different purpose: provide protection maximum and complete (shoulders, elbows). The V3's backbone is thicker, wider (with hard plastic "wings" going up to the shoulder blades) and CE Level 2 certified, where the A1 Pro compromises for weight.

Bionic Tech V3 vs. Bionic XTR Plasma : The Bionic XTR vest uses the flexible protection technology ‘Plasma’. Its back is slightly longer than that of the V3. However, that of the V3 is judged by some testers to have a better overall fit. The V3 is distinguished by its rigid hull and greater coverage of the ribs. This is a trade-off between Plasma Flexibility (XTR) and Maximum Rigid Protection (V3).

Compatibility

The upper panel of the back protection is removable. This feature is specifically designed to allow perfect integration with Alpinestars cervical protections BNS (Bionic Neck Support), ensuring that the neck brace rests as close as possible to the body.

Verdict Freenduro

The Alpinestars Bionic Tech V3 is not a minimalist vest. It is aimed at pilots who do not want to make any concessions on safety and who are looking for the highest level of certification on the market. Its positioning is clear: it is the most protective full-length vest in the Alpinestars range.

For whom?
The committed enduro driver, the competitor or simply the one who wants to ride with maximum peace of mind. Its modularity and relative lightness make it more versatile than it seems, but its main asset remains its almost impenetrable armour.

In conclusion, if your budget allows it and protection is your main criterion, Bionic Tech V3 is arguably one of the best choices on the current market. It represents the pinnacle of what Alpinestars can offer in terms of upper body safety for Motocross, enduro or ATV riders.
