Comfy skull cap
Great little skull cap. Helps prevent me getting a striped tan on my head through the vents in my helmet.Wicks sweat away from the front pads on my helmet, no sweat running onto my cycling glasses.Good fit under my helmet, helps keep my head cool even in the recent heatwave.Comfy and decent value for money.

A fantastic purchase!
I sweat a lot and don’t have much hair, so I have always struggled with sweat getting in my eyes when cycling. This scull cap helps that greatly. It also seems to keep me cooler, as it holds the sweat, which then evaporates off it and cools your head. I’d previously tried traditional cycling caps, and struggled to find one that fitted my large head and sat comfortably under a helmet. This skull cap does both of those things, and it is fantastic. It really helped me to keep cool and comfortable when cycling 330 miles in a recent heatwave!

A good piece of kit
Protects your skin from strong UV and helps wick away sweat. Just what I needed.

A great fit under the helmet.
A great fit, and cooler than a bandana without the peak of a cap obscuring my vision.

It works very well.
Been a hot one in the UK this summer at tines I was actually finding hard to see with the amount of sweat getting in my eyes on rides especially since I was wearing glasses which makes it harder to wipe them. This has totally solved all my issues I was very sceptical at first but works so well.

Excellent product

Great piece of kit
Bought this mainly because cycling in summer and finding helmet padding strips soaked in sweat and having to wipe brow frequently. Started wearing this and it effectively stops my helmet padding getting wet and means I don’t have to wipe sweat off brow. I also wear it for cycling in winter and it keeps my head a lot warmer. Has proven to be very durable and comfortable to wear, thin enough to go under helmet without affecting the fit. My helmet, like most cycling helmets is well vented, not sure how well it would work on a non-vented helmet.

Excelente
Extremadamente cómodo y muy transpirable.Obligatorio para no cargarte el casco si paras la cabeza o llevas pelo muy corto.El como se adhiere ayuda mucho a que no baje sudor a los ojos también.Calidad GripGrab.

erfect Under‑Helmet Protection Without the Bulk
The GripGrab Summer Skull Cap is exactly what I needed for hot‑weather rides. It’s thin, breathable, and disappears under the helmet—no pressure points, no slipping, no overheating. The UPF 50+ protection is a huge bonus, especially on long rides when the sun is relentless. It wicks sweat fast and keeps it out of your eyes, which makes a bigger difference than you’d think. Light, comfortable, and genuinely effective. A small piece of gear that makes every ride better. I chose white to better reflect the sun and keep cooler.
