Armored Tops

About Armored Tops

For riders who have hit the ground hard enough to start doing math. Use this guide to choose the right upper-body MTB armour for your speed, terrain, and tolerance for heat.

1. Mountain Bike Armoured Top Types (and When to Use Each)

2. MTB Armour Safety Standards and Certifications

• CE and the EN 1621 series are the closest thing to a universal language for impact armour. Even though EN 1621 was written for motorcycle PPE, the same inserts and certifications show up in cycling protection because it is a real lab test, not a vibes based promise.
  
• EN 1621-2 (back protectors) is the key standard for MTB armored tops. Back impacts on rocks and roots are common, and this standard defines two performance levels. Level 1 allows higher transmitted force than Level 2.
  
• Back protector Level 1 vs Level 2 is a meaningful jump. Level 1 targets a mean transmitted force below 18 kN, Level 2 targets below 9 kN (with limits on single hits too). Lower transmitted force is the whole point.
  
• EN 1621-1 covers limb joint protectors (shoulders, elbows). If your armored top includes shoulder caps, look for this number. Two performance levels exist, and lower transmitted force is better.
  
• EN 1621-3 covers chest protectors. Level 1 is force transmission only. Level 2 adds force distribution requirements, which generally means more rigidity or structure.
  
• Meeting the standard isn’t the same as best protection. Passing a standard only proves it survived a specific test setup. It does not guarantee coverage where you actually hit the ground, nor does it guarantee comfort, stability, or heat management. If the protector shifts, the rating becomes trivia.
  

3. Key Features and Trade-Offs in MTB Armored Tops

4. Comparing Mountain Bike Armour Design Options

• Option A: Hard shell (roost guard style)
  

• Ideal user: bike park, downhill, shuttle laps, riders who hit rocks at speed
  
• Strengths: great at deflecting sharp impacts, usually broad coverage, durable outer
  
• Limitations: heat, bulk, and sometimes poor pack comfort
  

• Option B: Soft armour (base layer or vest with viscoelastic inserts)
  

• Ideal user: trail and Enduro riders who still climb and want protection they will actually wear
  
• Strengths: comfort, mobility, fits under jerseys, usually better ventilation
  
• Limitations: less deflection for sharp point loads, and fit is critical (movement ruins coverage)
  

• Option C: Hybrid or modular
  

• Ideal user: wants hard protection zones plus soft conforming areas, or wants removable inserts for brace or washability
  
• Strengths: best balance when done right, can be more pack-friendly than full hard shell
  
• Limitations: more parts, more failure points, more ways to fit it wrong
  

5. Fit, Sizing, and Compatibility for MTB Armored Tops

• If it shifts when you shake your shoulders, it will shift in a crash. Snug is not vanity. Snug is keeping the back protector centred when you hit the ground.
  
• Back protector length matters. Too short and it misses the lower spine. Too long and it digs into your hips when you bend, which makes you stop wearing it.
  
• Pack compatibility is non-negotiable for most riders. Shoulder straps should sit on fabric, not directly on hard edges.
  
• Jersey fit changes everything. Tight jerseys can pull armour out of position. Loose jerseys can snag on shoulder caps and bunch under a pack.
  
• Neck brace and full face helmet users need a reality check. If the back protector is tall, it can interfere with brace movement or helmet clearance. Look for designs that explicitly allow insert removal or brace clearance.
  
• Heat, sweat, and mud decide what you will actually wear. If you ride humid summers, prioritize ventilation and quick-drying fabrics. If you ride dusty, open mesh collects grit and turns into sandpaper.
  
• Youth sizing is not just “smaller adult.” Shorter torsos and narrower shoulders make strap adjustment range and protector length more important than the label.
  

6. Care, Maintenance, and Lifespan of MTB Upper-Body Armour

• Replace after a serious impact. Cracks in hard shell, permanently compressed foam, or a protector that feels “softer in one spot” are all retirement signals.
  
• Wash the garment, don’t ruin the armour. Remove inserts when possible, hand-wash or gently wash the carrier, then air dry. Heat is the enemy of elastomers and adhesives.
  
• Check straps and buckles like you check tire pressure. Loose hardware means movement. Movement means your protection is somewhere else when you need it.
  
• Do not store it in a hot car. Heat cycling accelerates material aging and warps some plastics.
  
• If it smells like a biology experiment, fix the drying process. Sweat left in foam and mesh breaks down materials and makes you avoid wearing it.
