90Ninety Trilaminate BASE Spec – Complete and ready to dive from £2095
A diving holiday, does not always mean luxury live-aboards and warm blue waters.
Many diving holidays are now mini expeditions to all corners of the globe. When we began to develop our ideas for the O’Three 90Ninety Trilaminate Drysuit, weight was top of our list.
A fully spec’d Large 90Ninety Trilaminate is hitting the scales at just over 4kg, with Soft Socks 3.7kg.
We wanted a suit that would be the perfect travel companion wherever your diving adventures might take you, from 90.0000°N to 90.0000°S.
During the development period, we have reinforced key areas internally and externally and now the 90Ninety Trilaminate will meet the demands of experienced Cave / Tech and Recreational divers alike.
There are a multitude of quick replace systems to choose from. O’Three has incorporated into the 90Ninety Trilaminate two of the very best quick replace systems available.
Si-Tech’s ‘QUICK’ neck ring and KUBI’s wrist / dry glove systems are both robust, uncomplicated and functional.
You’ll never miss a dive again because of a broken seal.
Both these systems will accommodate Neoprene, Latex and Silicone seals.

Apeks low profile Auto Dump.
The most technically advanced and reliable automatic dump valve available.
Correctly adjusted, the valve gives effortless yet controlled hands free ascent as expanding air automatically vents from your dry suit.
Equipped with a manual over-ride system allowing you to vent the suit completely without disturbing your personal buoyancy setting.
This valve has the lowest profile with optimum dump rate.
It has an improved ratchet feel and is ergonomically designed for ease of use
Apeks Swivel Inlet.
Apeks robust and totally reliable inflation valve features an extra large recessed push-button allowing easy operation.
The smooth back plate gives protection from uncomfortable pressure loads and helps prevent cold air blasts through underclothing.
The valve sits low on the chest making it less prone to snagging.
The 360° rotation is a key feature of this valve to meet your personal hose configuration.
Carbon Braided Hose.
This high end hose features an external nylon safety braiding designed to resist the snags and abrasions that divers can often encounter.
The double braiding also resists UV rays out of the water, thus extending the lifespan of the hose.
OPTION
Original Automatic Dump Valve
Functions in exactly the same way as the Low Profile version.
For Re-breather users, with front mounted counter lungs, this valve will be easier to reach.
This valve can be supplied with a higher break pressure approximately twice that of the original, this higher break valve adds an additional small charge.
OPTION
Allowing you to answer the call of nature without having to remove your suit above and below the water.
Female friendly when used in conjunction with the ‘SheWee’
