Spidi says: Spidi Netrunner is a new, technologically advanced design that was developed to offer excellent protection to motorcyclists operating in warm and tropical climates. Significant ventilation is offered by the large mesh panels on the mid chest, upper chest, arms and back, allowing air to flow directly to cool the rider without compromising on safety. The main chassis is a high-tenacity Extra Tenax triple twisted nylon 6.6 offering excellent abrasion and puncture resistance. The Netrunner jacket has CE certification to the Pr En 17092-3:2017 Class AA standard, and it comes with ForceTech removable protectors in the shoulders and elbows, that are CE certified to the EN 1621-1:2012 standard. The jacket also come with a waterproof H2Out liner that can be used either inside or outside, It has a water-repellent barrier at wrists and bottom to offer excellent water resistance even in the heaviest of downpours. Netrunner features an innovative waterproof membrane that can be worn inside the jacket during a light rain, or outside in case of thunderstorms. The membrane has adjustable “gaiters” to adapt for the InsideOUT use. There are 3M® Scotchlite® reflectors for excellent nighttime visibility and there’s a jacket-to-pant zipper connection for additional safety. In order to ensure that the jacket can be tailored to fit perfectly, it has the Spidi integrated adjustment Ergofit System, with an adjustable E.S.T. fastener on the collar. For those unexpected rain showers, there’s a waterproof outside pocket, offering double protection when you have the waterproof H2Out liner on the outside.
This jacket is sold in “alpha” sizes (Small, Med, Large, etc).Generally speaking, the sizing of Spidi jacket run about one size smaller than normal US men’s alpha sizing.We’ve confirmed the smaller sizing through measurements and by trying them on our /info_pages/motorcycle_gear_fit_check.html.Spidi’s standard sizing chart for men confirms the smaller-than-normal fit.Our basic advice is to buy one size larger than you normally wear in men’s clothing.
To help you confirm the size you need in this jacket, I’ve put together the sizing chart below.You’ll want to measure yourself with a tape around both your chest and belly and choose a size using the chart.We’ve included a waist/belly measurement so you can make sure you are buying a jacket that is large enough for both your chest and belly.
The mid-section of this jacket isn’t cut as trim as a more sporty style jacket, and it has a very effective size adjustment setup through the belly and waist, so as long as the jacket’s max belly measurement is big enough for you, you should be able to find a fit even if you are much trimmer than the max belly size.
| Jacket Size | Max Chest | Our Estimate of Max Belly/Waist |
|---|---|---|
| Small | 38 | 36 |
| Medium | 40 | 38 |
| Large | 42 | 40 |
| XL | 44 | 42 |
| XXL | 46 | 44 |
| XXXL | 48 | 45 |
Note:If you plan on adding a back protector to this jacket, add 1” to your chest and belly measurements before using the size chart.If you plan to add the Thermo Jacket Liner also add 1” to your chest and belly (or 2” if you plan on adding both).
For reference, you can also have a look at Spidi’s standard sizing chart which includes similar chest size estimates along with recommended heights for each jacket size.
