A little bulky, but well made and reliable. A great helmet for those wanting a quality commuting lid. Also perfect for those just getting into cycling.
nice range of colours
retention system is little bulky
The Giro Trinity Helmet is the American companies entry level road specific helmet. At £39.99 it is slightly bulkier than Giro's more high end offerings. The helmet weighs 300g on our scales for a size 54cm-61cm (M), slightly heavier than the claimed 298g, but nothing to complain about. Although about 100g heavier than a premium lid, once riding you quickly forget.
There is ample padding on the inside that is pretty comfortable. The internal shape of the helmet is good too and felt comfortable on my head. With regard to helmets I would always suggest try before you buy, but the fit of this helmet is consistent with other Giro helmets, which seem to suit a wide range of different peoples heads.
The padding is also removable, meaning you can wash it if it starts to get smelly and sweaty after several rides – a feature you don't always see on entry level helmets at this price point.

The chin strap is different from the standard clip on other helmets. Although this slide through design (pictured below) is bulkier and heavier, it is ideal for children, because it is much harder to nip you skin when closing it. It is easy to adjust too.
The retention system on the back works well too. Giro call it an Acu Dial™ system, but all you need to know is that it allows simple one handed adjustment of the tightness of the helmet. It isn't as good as the Roc Lock system found on more expensive Giro helmets, which in addition to being much more minimalist, allows for more precise adjustment.
The Giro Trinity helmet comes in a wide range of colours which is nice. You can spend a bit more money and get the Giro Foray (£49.99 rrp), which is considerably better for just £10 more, however for those wanting a no nonsense, well made helmet for commuting, this is a great option. We would also highly recommend it to anyone getting into cycling, perhaps considering their first sportive or triathlon.
Being Giro, it also conforms to all the required EU safety standards.
