RH Plus Thermo Duo Hat

The Zero RH Thermo Duo skull cap delivers a surprising amount of warmth for its relative lack of bulk, making it ideal for keeping the noggin toasty on cold winter rides.

Constructed from five separate panels, the Thermo Duo manages to successfully tread the fine line between coverage and unnecessary material, at least for my averaged-sized head. The sides dip down slightly and completely cover one's ears, keeping them warm and preventing heat loss. When lining the front hem up with the rim of the helmet, the rear section comes down far enough to provide warmth without causing any bunching when in an aggressive position on the bike. All in all, I couldn't have asked for a better fit.

The material itself is quite stretchy, which enables it to be tugged into the right place, and is lined with a fleece material for warmth. In use, I found that the Thermo Duo was good up to temperatures of double figures, while I never really found its lower temperature limit. Though Zero RH don't make any claims about the material, I found it to be quite windproof and never experienced any issues when descending quickly.

Despite the warmth factor, the material is still quite thin, so it won't cause any issues with helmet compatibility. I sometimes find that I have to adjust my helmet straps to account for the increased helmet height, but this wasn't the case here.

The Thermo Duo is available in white and red as tested, or in three other combinations of white and black. Given that it will be used during winter for the most part, I would've gone for the black option myself, as the state of the local roads means that these things get dirty quickly. That said, I've used the white/red option on a couple of mountain bike rides and it has come out the washing machine looking none the worse for it.

Some reflective details are included on the sides, but these are only really visible if using the skull cap without a helmet.

At £28 full retail price, the Thermo Duo is definitely on the expensive side, even taking into account its fit and function – after all, it's still just a skull cap. However, with a bit of searching, it can be found for closer to the 20 quid mark bringing it more in line with the competition. At this price, I'd highly recommend it.

Verdict

A well-fitting skull cap which provides enough warmth for all your winter needs, albeit at a cost that puts it above much of its direct competition.

I've just recently bought a very similar speced skull cap from Dimex on EBay for £4.99. It is absolutely brilliant and washes up a treat. £26 for a skull cap strikes me as insane!

You can buy three of these for that price.
There's a great wind proof section at the forehead part of the cap. Just where the cold wind hits first.

Looks like something Ali G would wear, or a pair of pants. Think I'll be putting my money elsewhere.....

Probably knocked-up in a sweat-shop in Bangladesh for a couple of quid too...or are they trying to claim there's the high cost of R&D, wind-tunnel test etc to justify the rip-off price?

Make mine an Italian with Campagnolo on the side

4 quid at Aldi version is almost identical, albeit in black.

I've got a shaved head and even I sweat like a 1970s TV presenter with these. I prefer a buff tucked under a regular cap.
