Anyone who has experienced ‘brain-freeze’ when swimming in cold water will know how valuable triathlon skull caps can be to get you going! Our Heat-Tech Warmth Swim Cap offers fleece-lined insulation while maintaining optimal hydrodynamics through the water.
We have found the biggest complaint from swimmers who use one-piece caps is that they can feel ‘tight’ under the chin and have no adjustability. Our design is focused on making this cap the best fit possible, with hook and loop fastening under the chin to cater for different head sizes.
Part of a neoprene accessory range designed for year round training.
Key Benefits:

Thermal Cap
"Purchased this cap to complement my Aspire Thermal suit. Swam daily in the Lakes last week and despite some cold water temperatures I never experienced water shock. The cap is light, flexible and really warm. Remember though to use anti chafing stick on your neck when swimming for more than 20 minutes"

Toasty!
"Well, at least the top and back of my head is warm! I was flip-flopping between the strap-less cap and this one, and am happy that I went for this. The strap doesn't feel uncomfortable for my 30-45 minute swims. One thing is that water was getting trapped between the strap and in my ear, which felt uncomfortable. I solved this by putting swimming plugs in my ears."
