Giro

Stays put once installed. I don't detach it to charge it. I assume if you always take it off the helmet to charge it the clips will get worn out. It's a great addition a bike mounted tail light. It's bright enough to grab the attention of others.

I have this helmet in both white and black. Both were purchased months apart during a Gold Member promotion. I first purchased the helmet for the spherical, multi-level, rotational protection design. The numerous air vents keeps you cool, especially for those heavy sweater. It is very lightweight and I hardly notice I'm wearing it.

I recommend this helmet for its spherical, rotational design, its protection, and its ability to keep you cool.

I use arm sleeves instead of slathering on sun screen. It's faster than applying sun screen, and there's no clean-up afterwards. I've owned sleeves from many different manufacturers, and these have been my favorite. They're longer which allows you to pull them all the way up to your arm pits, and still have plenty to cover your wrists. The ribbed material may actually help them cool better, and they're a little thicker which likely means better protection from the sun. I'm only sorry I didn't buy a 2nd pair.

I like the helmet and visor feature. It worked great during my 70.3.

The only negative was my confidence with the visor's magnetic attachment. Its fine if you don't mess with it, but I would recommend anyone to 'set it and forget it' especially in a race. I was fine during the race, but My course was littered with visors with this magnetic technology- That said, love the helmet zero regrets about the purchase and there is no evidence that any of the lost visors were Giro.
