Giro Nine.9 MX Helmet

The Giro Nine.9 MX helmet is rooted in freestyle but equipped with a visor for ripping backcountry and trees. It's all about the freedom of choice, so the visor and earpads are removable. In-mold construction fuses the outer shell and impact-absorbing liner, so it's not only tough but also super light. 12 mammoth vents grab cool, fresh air when you're riding or hiking for glory, and the waterproof Weatherstrip vent pugs stop snow and wind chill. The Nine.9 MX has a compact shape with wide-open field of vision and gapless goggle fit. The Nine.9 MX is TuneUps compatible. –Vendor

Nine.9 MX Helmet
My first time using a helmet. A very good experience. Extremely comfortable and warm. I highly recommend the stereo ear flaps. The sound and convenience was unbelievable.

Great Protection that looks good too
Saved my life in the first day need I say more buy one!!!

Stoked on the Helmet
I'm really happy with the Giro.9 MX. It's lighter than my old lid, so in comparison feels like I'm wearing nothing at all (cue Ned Flanders vision). It's also warm. Only drawback is the shim thing on the back of the helmet snaps loose sometimes, but it's only one snap and is a minor issue.

Jibbed out
Put this baby on and you're the next Pete Olenick. No kidding, a great looking dome-piece. It's very comfortable, and I was surprised at how warm it was, I ski out east and I was shocked that I didn't have brain freeze when the wind chill was down to about -5 F. I highly reccomend the red color, I love it, you can't miss it. Although the visor did lift the helmet slightly at high speeds, it was easily remedied with a camouflage bandanna. Every one will be looking up to you when you sport this helmet. It's good all around, even if you're not a jibber, I love it in the trees, keeps the branches away from your goggles. Don't wear this unless you are an experienced skier, otherwise you'll look like a poser.

Light, Comfy, Safe
This helmet has saved my noggin more than once through skiing and extreme sledding. It's warm and light and comfortable. It also provides just the right amount of venting for those warmer spring days. I highly recommend this helmet.

Training Tips

Anaeroic threshold is when lactic acid starts to build up in your body as your muscles are not getting the oxygen they require. This threshold is typically expressed as a percentage of your VO2 max - the amount of oxygen per kilogram of weight that a person can use in converting fuel to energy. Elite athletes threshold might be as high as 90% of VO2 max.

Efficient running position allows you to run farther and faster. Keep the heel raise to a minimum, relax your upper body and hands, keep your upper body poised and quiet.

If you want to make progess in your training, join a running group. A commitment to meet on a regular basis with a group of like minded individuals will help you keep your focus.

An efficient long distance running stride will have you landing on your heal first and rolling to the front of your toes.
