Castelli Viva Thermo Skully
Sometimes Less is more, simple products are oftern better and nowhere is that more the true than with the Castelli Skully. The thin Thermoflex fabric is extremely warm yet provides excellent moisture mangement and easily fits under your helmet. The raw-cut edges eliminate bulk under the straps. This is perfection, simplified.
  • Thermoflec is warm, soft and stretchy
  • Flat-lock stitching
  • Raw-cut edge lies flat and doesnt bunch up under your helmet
Mr Moreno Very warm skully because it covers your ears which is very important. Also fits great under your helmet for cold rides. I like the cool designer look and graphics.
Mr Grant Great fit and comfy under the helmet.
Mr Pyke For those chilly days where a lack of hair means the noggin needs a bit of extra warming. Very comfortable and covers the ears and a fair bit of the neck.
Peter This is the second one of these I've bought. Great in in both cool and hot weather if you're follically challenged.
Ian M Great! The level of flex to fit all head sizes is just right. Feels like a quality product.
Grzegorz Very good winter cap. Looks great and doesn't disappoint from -5 up to 10*C.
Mr Cheeseman Well this Castelli thermal skull cap certainly keeps your head warm and cosy you don't build up any sweat which is always a bonus but most of all is certainly keeps your noggin warm
Mr Heredero A must to be wore under tour helmet. It is thin but warm so is barely noticed.
jeff Great piece of kit, not to thick that the helmet doesn't sit correctly.
Mr CLARK Very comfy, maybe not for the very coldest of days but ok if above 3C
Mr Obertelli Fantastic fit and very warm. Anther top quality Castelli product.
CLIVE Quality skull cap. Not too bulky but very warm.
Brian I already have 2 of these and they're great for winter rides. They keep your head warm in the coldest conditions but unlike some other skull caps they don't suffer from annoying wind noise in your ears when worn. I bought another in high viz yellow just to match kit I already have and the price on Merlin was best I could find.
Mr Jordan This works perfectly under my helmet, warm but not bulky and covers the ears.
Mr Goodier Really impressed with this Skully, great fit and doesn't ride up. Absorbs the sweat really well to.
Stewart Annetts This is a good bit of kit to have. Keeps the cold wind out and the heat in. Makes winter riding a bit more bearable
Mr Jordan I use Castelli headbands in the summer to stop the sweat getting in my eyes, so thought I'd try this Thermo Skully. What an excellent bit of kit. Fits nicely under my helmet (Kask Mojito) and works well with my sunglasses and doesn't interfere with them. Pulls down nicely over my ears and keeps my head nice and warm. Excellent.
Mr Fairhurst Great little skull cap warm without being to hot and bulky and great price from Merlin
Mr Kelly Excellent, very snug and warm under my helmet. A lifesaver, or at least and ear saver :-)
Rik66 Warm and a good, snug fit under my helmet. Much better than the old woollen beanie I had been using.
Mr Cooper Nice skully that keeps my head and ears toasty without leaving me with a line across my forehead (unlike my Etxeondo one). Absolute bargain at the sale price from Merlin.
Mr Brock Favorite cap I own now. Warm and hi-viz. How do you beat that?
Yves Great hat and comfortable
Mr Skarlis The material is thinner than the pictures and description make it look like. The hat is warm but not as warm as other true thermal hats that I currently own. My other complaint is the one size fits all. I have only worn it 2 times so far but it is a little tight. I wear between a medium to large helmet so I was surprised how tight this fit. Colors are nice and it is very stylish.
Tim Surprised just how thin this skully is, for me you don't know you are wearing it because of the design and does a great job of keeping sub zero tempreatures off your head. Excellent serice from Merlin cycles
bailey Really nice fit and warm yet cooling at the same time due to the wicking. Good item.
Darren Great hat to wear in cooler weather very comfortable for long rides
