Low Profile Swivel Suit Inflation Unit and Hose
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.
Comes complete with a 29″ (74cm) long medium pressure hose, with the more universal Seatec coupling.
Low Profile Automatic Dump Valve
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
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.
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.
Can be supplied with either Seatec or std Apeks coupling.
This hose comes as standard on the ccn range, for other suits there will be a small charge.
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 Go’

We have been working with manufacturers of Dry Glove systems and particularly Kubi so that they work perfectly with our neoprene wrist seals.
Due to various dry glove systems available and ways of fitting them to our suits please contact one of the team discuss the options –
+44 (0)1305 822820.
As with a front entry dry suit a hood attached system will tick some boxes, but will create one or two negatives.
Increased warmth and reduced flushing are the real benefits, however equalisation and neck seal setting is made harder.
Removal of the hood is obviously not an option when the weather improves.
There are several options available and you may have a preference, please call and we will be very happy to discuss those options in more detail –

Although made to measure is the ultimate way to have a suit made, at certain times of the year long lead times have to be considered. If you need a quicker completion, please consider the “off the peg – made to fit” options that are available on all O’Three suits.
The three key stages to O’Three’s customisation Made to Measure process. There are many factors that need to be considered when purchasing a made to measure dry suit. However, certain build parameters must always be adhered to.
Types of diving and individuals perception of just how a suit should fit can vary hugely. O’Three will always guide and advise on how we feel a suit should be tailored and customised, but ultimately, it is down to each person.
To ensure this 100% customisation is achieved, we always insist, where possible a fitting is done before your suit is complete. It is at this stage any adjustments that need to be made to the fit of your suit can simply and easily be done with no compromise to the integrity of any seam. Exact position of all components, valves, pockets etc are then discussed and marked onto your suit.
This might seem like a long winded way but it works. We feel this is the only way you can truly achieve a genuinely customised suit.
Stage 1: Choose Your Suit.
Either online, over the phone or in the shop. Get measured, decide on materials, seal combinations and colour ways at this first step.
If you choose to do any of the above remotely O’Three will always be pleased to guide you through this process. It’s not really that difficult as long as you remember some basic points as detailed in the measurement form section of this website. Please call if not 100% sure
Stage 2: The Fitting
This is the most important and critical stage of production. We know it’s a big ask, but it is at this stage, where every effort must be made to try and come down to our workshops here in beautiful Portland, Dorset, UK. We call this “a fitting”. This fitting date is given when you place your order.
Stage 3: Completion
After stage two, you will be given a completion date for collection or despatch of your new suit. Normally two working weeks after your fitting.
As well as the full specification above, the cost of your suit includes many customising options, some of which are listed below.

“Off the Peg – Made to Fit” Service
Taking into account our “Off the Peg – Made to Fit” service, our standard size chart should be used as a guide.
Although “Off the Peg”, O’Three will ensure that a good fit is achieved. Our extensive size range and the large amount of adjustments that can be made, for example, tweaks to the seals, arms and legs that might need shortening, or a change in boot size, means that we can correctly fit many shapes and sizes into “off the peg” suits…., we have been doing this for many years and we have called this process, “Off the Peg – Made to Fit”.
The MF5 Drysuit used in conjunction with O’Three’s PBB base layer makes it possible for O’Three to produce a suit that will fit you well throughout the entire year.
Seal alterations are free of charge.

PLEASE NOTE: Ultimately, it is you the wearer of the dry suit that is generating the heat, the suit you choose to wear (as long as it is a neoprene suit) is simply the insulator. A membrane style of suit will offer virtually no thermal protection.
The thermal guidance information above is purely that, a guide. If you are a petite lady and feels the cold when snuggled up in bed with a winter duvet on all year round, or you are a guy that wears a T-Shirt in the depths of winter your reliance on a neoprene dry suit from a thermal perspective is at either end of the scale.
Remember, if your base layer / under suit combination is coming up short at certain times of the year, just add flexible layers using the correct fabrics to improve your resistance to the cold. Think climbers and skiers. Get it wrong and you will increase bulk and buoyancy.
Please be sensible realistic and careful when choosing the appropriate thermal protection. We are all different.
Your life could depend on it.
