MTB Protection Guide: What You Really Need for Downhill Trails

Downhill mountain biking is raw, fast, and unforgiving. From high-speed rock gardens to gap jumps and steep technical chutes, DH trails demand absolute confidence - not just in your skills, but in your protection. Whether you're racing World Cup tracks or riding lift-accessed trails on the weekend, this guide outlines what you really need in MTB protection gear for downhill. 

Why MTB Protection Is Critical in Downhill Riding 

Downhill riding is inherently high-risk. Speeds are higher, features are bigger, and mistakes carry serious consequences. Protective gear is not optional - it’s fundamental. And choosing the right gear can be the difference between walking away or ending a season early. 

1. Full Face Helmet: The Cornerstone of Downhill Safety 

No piece of equipment is more important than a full face helmet when it comes to DH. These helmets are engineered to absorb high-speed impacts and protect your entire head - including the jaw and chin - during crashes. 

What to look for: 

  • Lightweight yet robust shell (carbon fiber or composite) 

  • Multi-density EPS liner for progressive impact absorption 

  • Advanced ventilation to reduce heat build-up on long descents 

  • MIPS or similar rotational impact protection system 

Alpinestars’ Supertech M10 offers a premium blend of lightweight performance, protection, and race-ready comfort. 

2. Knee Pads: First-Impact Protection with Race-Fit Comfort 

Knee pads take the brunt of most crashes - especially in corners or during failed landings. For downhill, they must provide hard-shell or reinforced foam protection without slipping or restricting movement. 

Choose pads that offer: 

  • CE-certified Level 1 or Level 2 impact protection 

  • Secure fit systems (straps or compression fit) 

  • Breathability and moisture-wicking materials 

Alpinestars A-Impact Plasma Elite Shield Knee Protectors are a top choice for aggressive DH riders who want robust protection without excess bulk.

3. MTB Body Armor: Chest, Spine, and Shoulder Protection 

For downhill racing or bike park riding, upper body armor is a smart investment. Modern MTB body armor is lightweight, articulated, and compatible with hydration systems or neck braces. 

Key features to consider: 

  • Integrated chest, back, and shoulder protectors 

  • CE-Level 2 impact protection (especially for spine) 

  • Low-profile construction to fit under jerseys or jackets 

  • Adjustable fit for different body types and riding styles 

The Alpinestars A-5 Plasma Chest Protector offers full upper-body coverage with industry-leading ergonomics and impact performance - designed for elite-level DH riding.

4. Elbow Pads and Impact Shorts: Often Overlooked, Always Useful 

While less common, elbow guards can be valuable on high-speed or technical tracks, especially for riders pushing the edge. Similarly, padded shorts can protect hips and tailbones during slides or awkward landings. 

Look for: 

  • Slim-profile elbow guards with flexible impact foam 

  • Shorts with integrated hip and lower back padding 

  • Comfortable fit that doesn’t restrict movement or pedaling 

These are smart additions for riders who race regularly or ride in bike parks with unpredictable terrain.

5. Gloves, Goggles, and Finishing Touches 

  • Gloves should provide excellent grip, abrasion resistance, and subtle knuckle protection. 

  • Goggles offer crucial eye protection and improved visibility in dust, mud, and low light. 

  • Neck braces, while optional, can reduce the risk of spinal injury during high-impact crashes.
