OUTWATER's intelligent textile system for active sun protection, controlled cooling and long-lasting thermal comfort.

At OUTWATER , we design our UPF50+ garments as true technical partners . Every detail is designed to meet the demands of hot, humid, bright, and sometimes extreme environments. The THERMOFLOW FIT system is the synthesis of this approach: a textile technology that not only protects, but also actively regulates, ventilates, and refreshes .

By combining a functional cut , technical materials , and natural thermoregulating properties , THERMOFLOW FIT™ allows your body to breathe, defend itself and perform better, whether you are at sea, in the mangroves, at the top of a trail or on the beach.

✅ Maximum UV protection UPF50+ even when wet
✅ Cooling effect activated on demand by humidification
✅ Ventilated and breathable cut that limits overheating
✅ Durable and breathable quick-drying technical fabrics
✅ Freedom of movement and extended comfort in hot conditions
✅ No feeling of dampness or discomfort , even during full activity

The heart of THERMOFLOW FIT™ technology is its ability to create a real feeling of freshness , even in the hottest conditions. By simply moistening your OUTWATER top—via splashing, misting, or a quick dip—you trigger a gradual evaporation process .

This physical phenomenon consumes heat at the surface of the skin: the water absorbed by the fibers slowly evaporates, capturing calories, which produces an immediate sensation of refreshment . Unlike soggy cotton or synthetic fabric that sticks, our fabric remains light, flexible and breathable , even when damp.

This efficiency is directly linked to our precise textile composition: 90% polyester / 10% spandex :

• Polyester , being hydrophobic, does not retain water but allows it to evaporate efficiently , contributing to cooling.
• The elastic spandex ensures a close fit without compression, even when wet.

Combined with the loose fit and natural ventilation , this system creates passive textile air conditioning , which lowers body temperature without on-board technology, without batteries, without compromise.

The structure of OUTWATER garments follows a logic of dynamic comfort: they do not adjust to the body like lycra, but create a breathing space between the skin and the fabric . This controlled loose fit allows air to circulate freely, creating a natural ventilation effect by convection .

More concretely:

• The warm air generated by your body escapes freely instead of stagnating.
• Cooler ambient air can enter, promoting evaporation and lowering the perceived temperature .
• The movements further accentuate this dynamic ventilation, like a small permanent current of air around the torso and arms.

This cutting architecture also provides superior freedom of movement , essential for outdoor activities where the range of motion is important: throwing, paddling, diving, climbing, running.

THERMOFLOW FIT™ is therefore not just a style choice, it is a form serving function : fighting against heat and allowing the body to move, breathe and adapt without constraint.

Our OUTWATER clothing incorporates UPF50+ UV filtering , the highest internationally recognized level of textile protection . This level guarantees that less than 2% of UVA and UVB rays pass through the fabric, effectively protecting you against:

• UV-A rays , responsible for premature aging of the skin,
• UV-B rays, responsible for sunburn,
• And to a lesser extent, UV-C .

Unlike some protections that weaken with use or contact with humidity, OUTWATER's UPF50+ treatment is intrinsic to the very structure of the fabric . This means that:
✅ The protection remains intact even after several washes ,
✅ It does not deteriorate under perspiration, rain or sea water ,
✅ It remains effective even when the garment is wet to activate the freshness effect .

This dual behavior (protecting from radiation and contributing to thermal regulation) makes THERMOFLOW FIT™ a global textile solution , suitable for intense, moving, and prolonged use.

The choice of materials at OUTWATER is not simply a question of comfort: it is guided by performance , durability and consistency with field uses .

Our textiles are made of:

• 90% polyester : a durable, lightweight, quick-drying fiber that retains its structure even after repeated use. Ideal for outdoor use, it won't lose its shape in moisture, won't stretch, and retains its thermal properties over time.
• 10% spandex (elastane) : essential for providing the elasticity needed for comfort , ample movement, resistance to twisting and joint freedom. The garment follows your movements without compressing you.

Additionally, key areas of our designs (back, sides, arm creases, etc.) feature breathable mesh panels , a flexible, airy fabric that improves targeted ventilation and accelerates moisture wicking . This further extends the feeling of comfort, reduces the risk of overheating and chafing, and promotes extended wear even in very hot weather.
