Product Information
The Mares Apnea Instinct 50 Lady Pants are the women's bottom half of the Instinct 50 freediving wetsuit, built from 5 mm neoprene with an open cell interior and a black lined exterior, and pre-shaped specifically for female anatomy. They are sold separately from the matching Instinct 50 jacket (code 422461) so a freediver can pair the fit she needs top and bottom.
Who it is for
These pants are built for women freedivers who want a snug, low-drag lower suit for demanding dives. The pre-shaped, high-waisted cut and soft open cell interior suit divers who spend long sessions in the water and need warmth and a close, watertight fit without a bulky bib getting in the way of a full breath.
Key details
- 5 mm neoprene body thickness, with 3.5 mm neoprene at the ankles and waist.
- Open cell neoprene interior clings to the skin to limit water infiltration and hold body heat
- Black lined exterior adds durability and abrasion resistance
- Waist-high design without a bib, leaving the rib cage free to expand fully on each breath
- Pre-shaped, pre-formed cut follows the female body's natural lines for fit, mobility, and reduced resistance
Compatibility and sizing
The Lady Pants are offered in sizes S1, S2, S3, S4, and S5 (pants code 422462) and are designed to pair with the Instinct 50 jacket (code 422461), sold separately so each piece can be sized independently.

Frequently Asked Questions
How should a wetsuit fit?
A wetsuit should feel snug everywhere, with no loose pockets at the lower back, armpits, or behind the knees where water can collect and flush. It will feel tighter than normal clothing on land, which is expected, because the suit works by holding a thin layer of water that your body warms. If you cannot take a full breath or the neck chokes you it is too small, and if you can pinch loose folds of neoprene it is too big.
What do you wear under a wetsuit?
Most divers wear a swimsuit, a rash guard, or a thin dive-specific base layer under a wetsuit. A slick base layer makes a tight suit much easier to pull on and cuts down chafing at the neck, shoulders, and underarms. Avoid thick cotton clothing, which soaks up water, bunches, and makes you colder rather than warmer.
How do you put on a tight wetsuit?
Work upward in small sections, pulling a little neoprene at a time rather than yanking on one spot, and get the suit fully seated at the ankles and knees before working on the hips and shoulders. A plastic bag over each foot and hand, or wetting the suit first, helps it slide into place. Grip with flat palms rather than fingertips, since fingernails are the most common cause of torn neoprene.
Does a thicker wetsuit mean a warmer wetsuit?
As a general rule, thicker neoprene insulates more, so a higher millimeter rating is warmer in the same conditions. Warmth also depends heavily on fit, suit style, seam construction, whether you add a hood, boots, and gloves, how long the dive is, and your own cold tolerance, so two divers in identical suits can feel very differently. Use thickness as a starting point and refine it against your local conditions and personal experience.
How do I care for and store a wetsuit?
Rinse it inside and out in fresh water after every dive day, and use a wetsuit-specific wash occasionally to control odor. Dry it inside-out first and then flip it, always out of direct sunlight, because UV and heat break down neoprene faster than anything else. Store it hanging on a wide-shouldered hanger or laid flat rather than folded, so you do not set permanent creases.
How long does a wetsuit last?
Lifespan depends far more on use and care than on age, so a suit dived hard in sun and chlorine may soften within a couple of seasons while a well-rinsed occasional-use suit can last many years. Signs a suit is finished include compressed neoprene that no longer feels buoyant or warm, splitting seams, and looseness in areas that used to be snug. Repairing small cuts and seam separations early adds meaningfully to a suit's life.
What is the difference between a full suit, a shorty, and wetsuit separates?
A full suit covers arms and legs, a shorty stops at the upper arms and thighs, and separates such as tops, bottoms, and hooded vests layer to add warmth where you want it. Layering a vest or top under a full suit adds core warmth and can extend the range of a suit you already own. Choose based on how much coverage you want, both for warmth and for protection against stings and abrasion.
Can I buy the Instinct 50 jacket and pants in different sizes?
Yes. The Instinct 50 Lady Pants (code 422462) are sold separately from the matching jacket (code 422461), so you can choose the size that fits your legs and hips independently of the jacket size that fits your torso and arms.
Why is the neoprene thinner at the ankles and waist?
The pants use 3.5 mm neoprene at the ankles and waist instead of the 5 mm used through the rest of the suit.
What does a waist-high design without a bib mean for freediving?
A bib normally runs up over the chest and can restrict a deep breath. The Instinct 50 Lady Pants stop at the waist with no bib, so the rib cage is free to expand fully, which matters for a freediver taking a maximum breath before a dive.
What sizes does the Mares Apnea Instinct 50 Lady Pants come in?
The women's pants are available in sizes S1, S2, S3, S4, and S5. If you are unsure which size matches your measurements, call 888-701-4017 or chat with DiveCatalog.com for help choosing the right fit.
