I have used the Halo variant skull caps for about 10 yrs year around. They are excellent for controlling sweat in the summer
and keep my scalp warm down to 20° (though I no longer ride much below 40°F anymore). Before the Halo I would routinely
get 'tiger stripes' on my scalp from sun through the vents.
One nice aspect of purpose designed caps such as Halo is that in high summer, at rest stops I can take the cap off, toss it
out in the sun on the concrete and it will dry significantly in 10-20 minutes. Previously when I used cotton sweat bands I
would actually have to call a ride stop every 20 miles or so to wring out the sweat band. This never happens with the Halo
and I never have sweat dripping off my eyebrows into the glasses like before the Halo.
