I’m sure that most everyone has heard the phrase “you lose most of your heat through your head” at least once and probably a lot more often. Sometimes it even gets really hyperbolic, with people throwing out stats like 70% or 80% of your heat evaporates here. Is this the truth or is it an long told fable?

Well, like so many things in life it isn’t black and white — the truth lies somewhere in the middle.

On a purely logical level it wouldn’t make sense that we lose that high a percentage of heat through our heads. The head accounts for such a small surface area that its rate of heat loss would have to be exponential to lose that much total heat, when compared to the rest of the body. Not surprisingly it doesn’t.

In the following we’ve taken a thorough look at skull caps and selected the most optimal for runners. Herein are reviews, details, and discussion — all you need to know about skull caps. Enjoy!

Ergodyne 6630 High-Performance

Nike Pro Combat Hypercool

Much like UA ,skull caps are very much the territory of a company like Nike. Their flagship skull cap is called the Combat HyperCool, and it is predictably quite good. It’s made from Dri-FIT fabric and comes with layered ventilation zones to make sure you stay cool and as dry as possible. This is one of the most minimalistic skulls caps out there, and it has a relatively thin construction. Despite its lack of bulk this cap will keep you pretty warm, and you can count on it in all but the most extreme conditions. Very reasonably priced (by Nike standards) there is a lot to like about the Hypercool.

Under Armour Mesh 2.0

Under Armour’s penchant for making good quality compressive gear makes them a shoein in the skull cap category. Their Mesh Skullcap 2.0 does not disappoint. The Signature Moisture Transport System wicks sweat and keeps your head dry. Plus you’ve got 4-way stretch material fabrication that allows you to move and offers a little support. Every once in awhile (especially if you size something wrong) Under Armour goes a little heavy on the compression for our taste. Not the case here. Highly recommended.

SweatHawg Shorty

Skull caps are often worn for the purposes of warmth, but this is far from their only utility. Working as an absorbing entity is equally as important in some cases. If you tend to sweat a lot, wearing a skull cap it one way you can work to remedy this. As the name implies the SweatHawg is a skull cap designed to suck up as much sweat as possible. This skullcap combines powerfully wicking stretch material with a high-absorbent brow band to stop excess perspiration. We’ve experienced this cap to stand behind its identity and when it comes to dealing with sweat this is one of your best options.

Icebreaker Pocket

If we’re being honest this hat is probably on the borderline between a skull cap and low profile beanie — the truth is it’s too good to leave off. We’re extremely partial to products made from Merino Wool (as you’ll know if you’ve read some of our other posts) and the Pocket Hat from IceBreaker is 100% Merino. As the name implies this hat has a slight build and easily stows in your pocket. It’s a fully functioning, breathable, and odor resistant hat made from non itch fabric that will softly protect your head. If your priority is to be comfortable you probably aren’t going to do much better than this hat.

Craft Active WindStopper

If a hat has “windstopper” in the name and plastered on the front of it you know there must be something to it. And in this case there is. Craft Active has produced a hat that stands up to the harshest of conditions, and is a trusted brand when it comes to top quality base layers. There are two primary ingredients in the cap’s material: air-channeled polyester which expels extra heat away from the body, and filament yarns which move moisture away. The microclimate created within this hat is ideal for endurance training and race day performance. The price is a bit higher, but the results are more than than worth it.

You may end up getting a little bit of hat head, but the insulation offered will be more than worth the ruffled hair. This cap fits nicely (not to rigid or loose) it deals with moisture in an efficient way, and it adds more visibility to your body for nighttime training. If we had to go with one skull cap recommendation this might be it, if for no other reason than it’s incredibly broad appeal.

To borrow a phrase from WebMd: “The real reason we lose heat through our head is because most of the time when we’re outside in the cold, we’re clothed but not wearing a hat.” It’s the difference between simply covered skin and not covered skin. Research has more or less shown that the head loses heat at the same rate as any other part of your body.

So, there’s that myth busted. This does however leave the the task of making sure our heads are well covered in cold weather. If you’re training in the winter (or summer for that matter) you need some good protection for your dome. There’s a million hats to choose from, and there’s also skull caps — a sleek and high performing alternative.

Whether you’re training in the bitter winter cold or blasting summer heat skull cap can do quite a bit to help your body thermoregulate itself. There is a reason a lot of NFL players wear them for a competitive advantage. Running bands can be another solution, however we’ve found their lack of full coverage to provide less benefit when it comes to staying warm or remaining cool. Be sure to pay close attention to sizing, the last thing you want is elastic constricting your head. So that’s it, these are are our top eight — cheers to warm ears and a sweat free brow!
