Good Helmet poor fastening system

This is a good Helmet and it initially felt like a great fit too, but once out on the rough trails it was sliding all around my head, therefore I probably should have purchased a size smaller. So if you're tempted to buy this don't buy it online like I did and instead go in to the store and try it on first.

Good Fit and good price

Good Fit and good price recommended

Bad fit

No adjustability and one very unique size No ventilation system either Good delivery but awkward shape


I bought this because my friend recommended this product to me. Where I use it I feel safe. I have crashed with this on and it has protected me from everything I do. I highly recommend this helmet to beginners.

Spot On !

I love this lid, fits a treat, feels so much better than a standard road helmet ( not that i go anywhere fast ) the extra protection sides & back is barely noticeable when it is on. Get one you wont be disappointed.

Amazing Value with good protection

It's a very practical helment it offers extra protection to the rear and side which older style and road style helmets do not offer( I'm pretty sure you can ski in it) . The only downside is the lack of ventulation in summer months as in there is very little when compared to the premium brands like Poc.Also the visor looks like it moves but you need a big star shaped screw bit to move it up and down (odd choice). However for the money its the best helmet you can buy for off road/single track riding.

Why have I purchased a black B'TWIN mtb helmet ?

I am 76 years old and have spent many , many years cycling on ever more dangerous and congested roads here in the UK . I have owned a variety of helmets since they first became available , but without doubt this model is by far the most stylish and comfortable . It looks good , fits fine and is both lightweight and excellent value for money .In fact , I really like wearing it . Sadly I think it may be some years before I take it into the mountains ! !
