GreenGoma™ Swim Cap*

Regular price $ 38.00

NOTE ON HOW TO PUT IT ON:  People intuitively want to put their head into the bigger of the two openings, but that won't work. Put your head first into the small opening of the cap as that part goes around your neck and the big part is your face. You'll know if you have it on correctly when the GreenGoma logo is on the back of your head.


  • 3 mm GreenGoma™ #9 Limestone derivative rubber for insulation and warmth
  • A thin profile chinstrap maximizes comfort, while minimizing the potential for chafing and breathing obstruction
  • This cap will add 5-7 degrees (F) of warmth and water temperature comfort
  • Added buoyancy of the head makes it easier to lift the head to site and breathe
  • Back of the neck is cut high to avoid chafing while sitting or wading in water 

A TIP FROM EMILIO: Swimming in really cold water? Try Emilio's GreenGoma™ Swim Cap Sandwich

Ingredients: 1 GreenGoma™ Swim Cap, 2 latex rubber or silicone swim caps.

  1. Put on the first latex rubber swim cap. Make sure it covers your temples and forehead.
  2. Put on the GreenGoma™ Swim Cap over the first latex swim cap. Again and more importantly, make sure it covers your temples and forehead and that it sits just above your eyebrows as shown in the photo. This will eliminate "Brain Freeze", or "Ice Cream Headache."
  3. Finally put on the last latex cap. Make sure it covers the front and back of the GreenGoma Swim Cap.

If done properly, your hair will most likely be dry when you exit the water, but more importantly, your head and your body will stay warm...and your fingers will actually work! I have raced Escape from Alcatraz over a dozen times (twice without a wetsuit). I have raced in the Puget Sound, the English Bay in Vancouver, and in the Milford Sound on New Zealand's South Island. All are races where the water temperature was between 48 - 54 degrees F (9 - 12 degrees C). This Sandwich works...I guarantee it!

wet suit and cap

i also bought a suit w/ the cap. both are excellent for warmth and flexibility. Not sure if i'm moving any faster, but that wasnt my goal. it's a joy to be in the water even in low to mid 50's temps.

Great Swim Cap

I swim several days a week, year 'round-my body temp thermostat is a bit off so I tend to be cold when others are fine. This swim cap is very effective at allowing me to swim and makes a several degree difference. So for anyone who needs help when the water temp is low this is the cap for you.

Good, but too small for me

I’m sure it is great, but if you have a big head it might be too small. At least I thought so. The chinstrap is too tight on me. Otherwise very nice.
