FEATURES
The D9 comes with all the features you'd expect from a top-of-the-line drysuit from SITech valves, a flexible TIZIP, neoprene warm neck, neoprene cuff protectors, telescopic torso and internal braces.  The D9 is a front entry drysuit so you can get in and out of it without the need for a buddy to seal you in or let you out.  The TIZIP has a Velcro zip protector to protect it from damage and a Velcro tab on the chest to help with hose routing. 

SIZE
The first thing you realise about this drysuit is just how small it packs down to; because it is a membrane drysuit, with socks and a flexible TIZIP it packs down smaller than my wetsuits.  The D9 will pack down into its bag to about 65x20x25cm and weighing only about 2 kilograms (a Medium Large complete in its bag with hose weighs 2.2kg) it is perfect for travel.  When I first went diving out in the Red Sea I thought it was weird for people to take a drysuit as I'd only ever used them in the UK in cold waters but it makes a lot of sense;  the worst part of diving in the Red Sea later in the year is getting out of the water.  Later on in the year the wind starts to pick up and climbing out of your wetsuit is a damp cold nightmare but a drysuit solves this.  And everybody who has done more than one dive knows the awful sensation of pulling a cold, soggy wetsuit that hasn't dried; only chilled for a second dive, whilst the smug drysuit divers just pull their suits on without a second thought.

MATERIAL
Whilst being thinner and lighter than most membrane drysuits the materials the D9 is made from is still quite tough to protect from abrasions.  On the inside the internal lining is a much softer and all of the internal seams have been taped for comfort.  The breathable nature of the fabric increases the comfort especially if you're standing around in the sun. The taped seams are sealed using an ultra-sonic weld to seal every little gap to prevent even the smallest of leaks.  Fitted with a TIZIP and flexible socks this drysuit is completely flexible except for the chest and shoulder valves, everything else, including the dryzip, is completely flexible.
