A triathlete can compete in the most punishing weather conditions, and thanks to trailblazing textile technology, she's covered. So why can't that same woman get in the shower and keep her hair dry? Because our hair protection "gear" is a crunchy disk of plastic stuck on a wimpy strip of elastic. In contrast, Turbella has more in common with the most elite outerwear than with any shower cap. Because for the daily shower to be free of hair hassles, our gear needs to work.
WATERPROOF. BREATHABLE. HEAT-WICKING. QUICK DRY. ANTIMICROBIAL.
The most demanding outdoor apparel brands in the world rely on 37.5® Technology to make their products perform better. And so do we.
Patented 37.5® Technology is printed on the inside of the Turbella 2-in-1 and Superpower Cap. These active particles dramatically speed up the waterproof/breathable (WP/BR) fabric's vapor diffusion to keep your hair dry and your style set. 37.5® Technology is made with naturally derived materials (activated carbon from coconut shells and volcanic sand) and never washes out. Turbella's fabric with 37.5® Technology meets and exceeds the waterproofness, breathability and moisture management of Gore-Tex®, The North Face, and Patagonia H2No.**
WHY WATERPROOF ISN'T ENOUGH
Our bodies emit moisture vapor constantly, especially from our heads. Regular shower caps keep water out by using a waterproof material like plastic, which makes your head sweat even more, and traps that sweat vapor inside the cap. It’s not enough to keep shower water out; the environment under the cap must also stay dry. 37.5® Technology moves moisture away from your head in the vapor stage, before it builds up to liquid sweat or damages your hairstyle.
WHY WATERPROOF AND BREATHABLE ISN'T ENOUGH
Water vapor doesn’t start moving through waterproof breathable fabrics until the humidity under the product reaches about 70% relative humidity. That's steamy. At that humidity, your styled hair is already compromised.
37.5® Technology pulls moisture directly to the inside of the fabric and then drives it through the membrane, keeping the relative humidity inside at around 37.5% so your style stays perfect longer. 37.5® Technology improves moisture vapor transmission (MVT) and drying time by 30 to 100%.
The science of 37.5® Technology
Here's how fabric powered by 37.5® Technology measures up:
MEASUREMENT |
FRAME OF REFERENCE** |
|
WATER RESISTANCE This is the amount of water pressure (in millimeters) a fabric can withstand before leakage occurs. The higher the number, the more water pressure it resists. |
2,112mm - Wind-driven rain 7,400mm - Hurricane-force rain 16,700mm - US Military spec for waterproof gear 20,000mm - Turbella with 37.5® Technology |
|
BREATHABILITY The Moisture Vapor Transmission Rate (MVTR) is the amount of water vapor (in grams) that can pass through a square meter of fabric during a 24-hour period. The higher the number, the more breathable. |
6,000-10,000 - Most rainwear with a laminate 10,000-15,000 - Gore-Tex® Performance 3-layer 15,000 - Gore-Tex® PacLite/Performance 2-layer 20,000 - Turbella with 37.5® Technology |
* The ratings of our waterproof/breathable fabric powered by 37.5® Technology are: Water Resistance: 20,000mm or better, Breathability: 20,000g/m⊃2;/day or better
** There isn't one universal test or rating for water resistance or breathability. The above references use the same apples-to-apples test method. For water resistance, it's the water column method; for MVTR it's known as the JIS L 1099 test. The cited waterproof/breathable ratings for Gore-Tex® Performance 3-layer and Gore-Tex® PacLite 2-layer are compiled by outdoor retailer REI.
