Hydrus 3L (3-layer) is a waterproof breathable three-layer fabric designed to keep paddlers completely dry in extreme conditions.

The outer layer is super-tough woven nylon, providing long lasting abrasion protection and features a durable water repellent (DWR) coating which repels water. The mid-layer utilises a proprietary polyurethane micro-porous coating, allowing water vapour to transfer from the inner layer to the outer. The soft, knit polyester inner layer is engineered to help manage moisture, wicking it from the inside out.

The result is an exceptionally waterproof, breathable alternative that stays dry and comfortable. 

• Hydrus 3L socks with gravel guard
• Re-sized (5cm larger) XXL waistband
• Neoprene waistband with adjustable “hook & loop” tabs
• Factory sealed seams

This model has a relief zip in the front, same as the men's dry suits (some of the pictures above show the pants without the zip).
These are essentially the same pants as Kokatat Hydrus 3L Tempest Pants with Socks, with a zip inserted (in Kokatat Factory, USA).

These pants are ideal for sea kayaking and kayak fishing - they will keep you warm and dry in the cooler weather - keeping off the wind chill you get with damp thermals from launching and landing your kayak.

Look after the socks - wear footwear over the top to protect them.

After use, make sure your pants are well rinsed and hung loose to dry. Check additional care instructions on label.

Colour: Some are Dark brown-grey. Some sizes are now a paler grey colour.
Relief Zip (front): Yes

Also available without relief zip (separate listing)

Size Guide (Men's sizing):

We use these - they are awesome kayak fishing you won't believe the difference!

KOKATAT MEASURING GUIDELINES

Do not measure yourself. Measurements should be performed by an authorized and trained Kokatat retailer. Failing that, someone you trust to get in close with a cloth measuring tape.

Just relax! Look forward and stand up straight with your feet about 12 inches apart. 
Don’t move around and look straight ahead. Stop looking at your measuring partner or the floor. Remember, relax!
Take measurements in - preferably washed - street clothes and bare feet.
DO NOT make allowances for insulation layers under the suit. Kokatat patterns are designed to allow for adequate layering under dry suits. 
All circumferences should be taken at the widest point. If you happen to be measuring your wife or mother-in-law, you may want to refer to this as… oh, forget it.
Again… measure twice, cut once. 

The following measurements should be taken on the person’s front side:

WAIST: Measure just above your hip bone where your body bends when bending sideways.

HIPS: Take this measurement from the side to ensure the correct placement of the tape. Place the tape around the hips and across the widest point of the buttocks. This might be a good time to come up with a descriptive word other than “widest”. Make sure that all pockets are empty.

INSEAM: This is also referred to as the “crotch to ankle bone” measurement for those very secure individuals. Have the person stand with legs straight and feet about 12" apart. Have them hold their hand to the side, with palm facing out. Place the end of the measuring tape between their first two fingers. Ask them to place the hand with the tape in their crotch area, snug up against the body. Just relax! Stretch the tape straight down your ankle bone. Ask the person to look straight ahead, turn their head to the right and cough.

GIRTH: This measurement is for the entire torso length. Place the tape at the base of the neck on top of the shoulder. Run the tape down the front, through the crotch and up the back to the starting point on the shoulder.
