Sailing Hat Southwester Ozean 900 designed for intensive offshore sailors seeking lasting protection from the rain, wind, and spray.

This sailing hat is ultra waterproof, windproof, water repellent and breathable. This southwester stops water getting in at the neck and the visor offers an optimised field of vision and protection.

Storm tested (450 L/hr/sqm) for over 24 hrs. Waterproof >20,000mm. Taped seams.


Very breathable, wicking away the moisture generated by your head. RET = 12.

Easy to use

Adjustable head size. Cord to keep your Southwester on in the wind.

Water repellent

Specially treated so water slides off the fabric's surface.

Salt water resistant

Treatment preventing hydrolysis (which alters properties of standard coatings)


Windproof, breathable membrane stops the windchill effect.

What does a "waterproof" component mean?

It's a fabric's resistance to water penetration. This is measured using an approved water pressure test. Since the average pressure of rainfall ranges from 1000 mm to 2000 mm, we consider a fabric to be waterproof from 2000 mm onwards. Our products are able to resist a pressure which varies from 2,000 to 10,000 mm. They are, therefore, extremely waterproof and suited to all weather conditions, even the most extreme.

What is a waterproofing test or "shower test"?

Approved test where the garment is placed under a shower simulating different weather conditions. All our products are certified fully waterproof having been tested for 4+ hours in rain of 100 L/hr/sqm to 450 L/hr/sqm depending on the product use. To put this into perspective, the highest recorded rain fall was in the USA in 1942, when 174 L/hr/sq.m. fell over 4.5 hours (NOAA). The average rainfall in Paris is 2 L/hr/sq.m. (

What are sealed seams or strips?

These are seams that are sealed (or taped) using thermally-sealed watertight strips. They are placed behind the seams and are essential to making the garment watertight as they prevent water from penetrating the fabric by capillary action (water penetration through absorption by the threads and/or stitching holes).

What is a waterproof and breathable HYDROPHILIC membrane?

The membrane works in stages to wick away perspiration. Firstly, the fabric absorbs water vapor until it is saturated. Then, due to the difference in pressure between inside and outside the jacket, the fabric disperses the water vapor outwards. The main advantage of the hydrophilic membrane is that it does not contain pores; consequently, there is no need to constantly rinse the fabric to wash off any salt water crystals. Breathability therefore remains constant over time.

What is hydrolysis?

Hydrolysis is a chemical process whereby a membrane or standard coating is broken down by salt present in sea water and sea spray. All Tribord membranes and coatings use a technology which halts hydrolysis, allowing the garments to retain their essential properties for long periods of time. The garments don't degrade and remain waterproof and breathable for a long time.

What does water repellent mean?

A quality achieved by applying a hydrophobic, water repellent treatment to the fabric. This process prevents water from sticking to the fabric's surface, so less water is absorbed. When movement is added to the equation, water glides over the fabric. This means the fabric is water repellent. Thanks to its water repellent properties, water does not soak into the outer fabric, so the jacket stays light and dries more quickly.

What is breathability and the RET index?

A fabric's breathability is its ability to disperse water vapor produced by the body (perspiration). It can be measured using the RET index (Resistance to Evaporative Transfer). The RET is a resistance index; the lower the value, the greater the breathability of the garment. RET between 6 and 12: very breathable; RET between 12 and 20: breathable; RET above 20: not breathable. Our products are very breathable, with a RET between 7.2 and 12.

How important is windproofing?

Protection from the wind is critical, as wind can chill the body significantly whether you are active or at rest. According to the "windchill" model, which measures how the air temperature feels when factoring in the wind and cold: at a temperature of 41°F combined with winds of 19 mph, the temperature felt will be 32°F. If the air temperature is 32°F and wind speed is 19 mph, the temperature felt will be 21°F. The materials used in our products help to counter the windchill effect.
