Specialized S3 Helmet

Rated 3.8 out of 5 by 4 reviewers.
Rated 3 out of 5 by Great design poor build quality I bought the S3 to replace my ageing Giro. The fit and feel are great. The click wheel retention system works a treat. The downside is that the finish and build quality are below par. Jagged edges, poorly applied decals and parts of the black plastic coming away from the expanded polystyrene. With hindsight I should have bought a Kask or Giro. Buyer beware. Cycle Surgery do not do refunds on helmets! 26 March 2014
Rated 3 out of 5 by Mushroom head I thought I'd try a specialied helmet because I have an oval shaped head measuring 58cm and was told that this might be a good fit. It was a perfect fit and felt very comfortable and lightweight. Quality looks great too. Sadly I had to return it because it looked more bulky than I thought giving that dreaded mushroom look. 04 November 2013
Rated 5 out of 5 by Saved me from a serious injury I bought one of these a year ago. I went over the handle bars in a rock park and landed on my head straight on to a slab of rock without getting a hand down. The helmet cracked in two places and I got away without a scratch and just a stiff neck for two weeks. I went back to cycle surgery to get a new helmet and ended up getting the same one. It was 20% off and they got the correct size in from another shop. Great service. Thanks 22 October 2013

Specialized S3 Helmet

The Specialized S3 helmet is a ultra-lightweight and versatille performacne helemt for the rider wanting that little bit more from a helmet. With Specializeds 4th dimension cooling system and patented Kevlar-reinforced Inner Matrix, its a helemt speced out as high as most bikes.


  • Complies with one or more of the following safety standards for bicycle helmets: CPSC, SNELL B90A, CE and AS/NZS
  • Patented Kevlar-reinforced Inner Matrix saves weight and allows larger, deeper channelled vents
  • 4th Dimension Cooling System w/ Mega Mouthport
  • Thin, soft and lightweight 4X DryLite webbing won’t stretch out with sweat or water
  • Ultralight Mindset micro-dial fit system with height adjustability for perfect fit and comfort
  • Instrap system minimises strap length and reduces strap contact for more comfort
  • Tri-Fix web splitter for improved comfort and ease of strap adjustments
  • Lighter, low-profile buckle
  • Quadruple in-moulded shells protect the foam and your head
  • Patented clip-on matching colour visor included


Kevlar Inner Matrix
Dual Density EPS foam and Kevlar Inner Matrix reduce excessive material to create an ultra-light helmet, while still surpassing the industry's toughtest safety standards. Plus this internal structure minimizes weight and maximizes vent size, allowing larger vents and deeper channels.
Micro-adjust Mindset fit system lets the rider fine-tune the fit of the helmet with one hand. Tactile and audible dial adjuster ensures a precise and secure fit for all head shapes and sizes. Design is 30% lighter than original Pro Fit 360.
4th Dimension Cooling
4th Dimension Cooling technology with Mega Mouthport provides unmatched airflow in an ultra-lightweight package. Strategically placed vents and channels provide maximum airflow over the head to cool the rider during high-intensity efforts. At slower speeds, the large top vents allow heat to escape through passive ventilation.
Unique Tri-Fix retention system simplifies strap adjustments, improves ergonomics, and reduces weight. Fixed ear loop provides generous ear clearance for greater comfort. Ultra-light straps and sculpted adjustment mechanism eliminate redundant webbing and buckles found on most helmets.
