The 661 range of Mountain bike Full Face Helmets featuring the Comp Shifted Helmet

SixSIxOne is pushing product development to the limits to build a range that exceeds the standards within the motocross and mountain bike industries. Their designers incorporate the newest technology to provide quality products that excel in comfort and protection.

Technologies for the 661 MTB Comp Shifted Helmet:

  • Neck Brace Compatible: Certain technologies work better if the supporting products are designed to work in conjunction with each other. Neck braces are one of those technologies that need products design specifically to work with other safety equipment. Certain helmets, chest protectors, and roost deflectors are designed to work in conjunction with a neck brace to maximize comfort, fit, and motion.
  • Full helmet Venting System: The Full Helmet Venting System, or FHVS, is a system designed to give maximum airflow by linking channels and vents to create a vortex of airflow pushing warm air out of the helmet allowing cooler air to keep you cool.
  • Panorama Eye Port: The Panorama full view eye port is designed to give maximum peripheral vision and allow any goggles to fit without interference.

MTB Helmet specifications:

  • Polycarbonate shell
  • Interior channeling to aid ventilation
  • 12 exterior ports
  • Suitable for: BMX and DH

This helmet conforms to, or exceeds EU Standards only.

The 661 range of Helmets is available from Chain Reaction Cycles, the online bicycle store for the amateur to the professional cyclists.

Rated 4.7 out of 5 by 112 reviewers.
Rated 4 out of 5 by Great value, light weight... a little warm in summer First full face helmet, bought for racing the steeper rocky sections of the Victorian Alpine Gravity Enduro Series (Australia) Light Weight and confidence inspiring Could do with more vents as it got a bit hot in the warmer weather although I have no other full face helmets to compare it to. 15 July 2014
Rated 4 out of 5 by what a bargain! this is a brilliant product and will protect heads fiom any direction. is light and cofortable an nice and hard wearing too. for the money it is absolutely fantastic.....one problem-the inside isnt easily washed! 07 July 2014
Rated 5 out of 5 by 661 kids helmets great fit and looks great. kids loved them. would recommend 09 May 2014
Rated 5 out of 5 by Отличный лёгкий шлем! Это второй у меня фуллфейс от 661, так же модель Comp. Весит 860 грамм всего, на голове сидит отлично, совсем не напрягает шею. Падал лицом в землю и в асфальт, защищает на ура! Единственный момент, при падении сразу же отрывает центральное крепление козырька, и я затягиваю посильнее болты по краям! Можно было бы как-то доработать этот момент с креплением, чтобы козырёк не ломал его каждый раз, а так отличный шлем! Смотрится стильно, сидит удобно! 07 May 2014
Rated 5 out of 5 by Hard Hat a good helmet that's both strong and light. not the most airy of helmets but great for the price. definitely recommended 23 April 2014
Rated 5 out of 5 by Buen casco y ligero Se puede decir que es un buen casco despues de dos caidas con el no le a pasado nada a mi me a salvado de estar sin cara es muy comodo y tiene buena visibilidad 12 March 2014
Rated 4 out of 5 by Great helmet - for the price I can not tell how this helmet holds up in a hard crash, since I have not crashed hard with it yet. The inside is not washable, you can't release it and put the soft stuff in the washing machine. So if you are looking for a long lasting helmet which smells like parfyme I would try another one. :) But the fit and feel is great for the money. Nice with "simple" black and white design. But as usual you get what you pay for, there is always a reason why one product cost 60€ and another one cost 200€. 28 February 2014
Rated 4 out of 5 by Ottima qualità. Costruito con materiali di qualità, abbastanza leggero, prezzo conveniente. 26 February 2014

Answer: 
mmm... you would definately need to get xs, i think the xs would be a bit to small for the 3.5 year old, and xs may just fit the 6 year old, (try looking out for a youth helmet, they would have better sizing options)

I have a very small head and a "youth" size helmet but it's slightly on the tight side. Is it good to have it really tight so it doesn't rattle around while riding and will it compress after a few uses making it a perfect fit?

Answers

Answer: 
A helmet should be a tight fit; but not uncomfortably tight. Due to the nature of a helmet being designed to last for a long time; it is unlikely that the padding will compress.

Answer: 
661 sizing suggests Medium for 57-58, and Large for 59-60cm. If you find yourself on the cusp between two sizes I would suggest you opt for the larger option.

Answer: 
The MTB and Road cycling helmets we sell comply with British Standard BS EN 1078:1997 this is the British and European standard.
It covers helmet construction including field of vision, shock absorbing properties, retention system properties including chin strap and fastening devices, as well as marking and information.

This is not AS/NZS 2063, so it is not technically legal to use in Australia.
