Mares Extreme Undergarment
RM704.00
The Mares Extreme Undergarment is a purpose-built dive undersuit designed to sit beneath a wetsuit or drysuit, adding an extra layer of insulation and moisture-wicking comfort. The stretch-lycra construction moves with you without bunching or restricting, and the fleece or brushed lining traps warmth efficiently. Ideal for back-to-back dives at Sipadan’s multi-tank liveaboard days, where staying warm between tanks matters.

Suited for Malaysian Dive Sites
The Mares Extreme Undergarment performs reliably across Malaysia’s premier diving destinations. Whether you’re exploring Sipadan’s multi-tank liveaboard days, or venturing to new reefs and wrecks, this wetsuit delivers the warmth, flexibility, and comfort you need on every descent.
Care & Maintenance
- Machine wash on a gentle cycle in cold water – it’s the only wetsuit piece that tolerates this.
- Tumble dry on LOW heat only; high heat shrinks and damages the lycra.
- Wash after every use; sweat and salt build up fast in a close-fitting base layer.
- Replace when the fabric loses its stretch – a loose undersuit bunches and reduces comfort.
Final Verdict
The undersuit is the unsung hero of the dive kit bag. The Mares Extreme Undergarment does its job quietly – keeping you warm, dry, and comfortable beneath whatever you’re wearing on top. Once you start using one, you won’t go back to diving without it.

I purchased the Mares Extreme Undergarment on a whim, and I must say, I’m impressed. The material is comfortable and breathable. It’s been a game-changer for me during dives. I’ve noticed a significant improvement in my Buoyancy Control.

What sets the Mares Extreme Undergarment apart from other wetsuits is its unrivaled fit and flexibility. Does the manufacturer use advanced textiles or perhaps an innovative layering system?
Imran Hanafiah –
Thank you for sharing your thoughts on the Mares Extreme Undergarment. The unique fit and flexibility of our wetsuit are indeed some of its standout features. Our manufacturer has carefully designed the undergarment using a combination of advanced textiles and innovative layering systems to provide a comfortable and leak-free seal. Specifically, the undergarment utilizes a combination of neoprene and a stretchy, Quick-Dry fabric. This allows for enhanced flexibility, making it ideal for watersports enthusiasts. I’m glad you’ve experienced the benefits of our product. If you have any further questions or would like to explore more products from Mares, please feel free to ask!

I’m blown away by the durability of the Mares Extreme Undergarment. I’ve worn it for over 50 dives, and it still looks and feels like new. One thing I’ve noticed is that the zip can be a bit finicky. Is there a way to improve the zip mechanism?
Junhao Lo –
Thank you so much for your review of our Mares Extreme Undergarment! We’re thrilled to hear that it’s held up to 50 dives and still looks and feels like new. Regarding the zip mechanism, I’d be happy to pass on your feedback to our product development team. In the meantime, I’ve included a tip to help you use the zip more smoothly. Please tryZippering the Mares Extreme Undergarment when it’s moist, as this can make it easier to glide smoothly. Additionally, you can also apply a small amount of lubricant, such as silicone-based spray, to the zipper tracks to improve its performance. Your feedback is invaluable to us, and we appreciate your input!
Kelly Wong –
What are the key components that contribute to the wetsuit’s thermal regulation? Is it the neoprene thickness or perhaps the inclusion of thermal linings?
Imran Hanafiah –
Thank you for your question, Kelly! We’re glad you’re interested in the Mares Extreme Undergarment’s thermal regulation. This wetsuit features a combination of key components that contribute to its thermal regulation. Firstly, the neoprene thickness plays a significant role, as the 5mm and 4mm neoprene suits provide excellent insulation. Additionally, the inclusion of thermal linings such as the Pro Flex lining, which enhances flexibility and reduces moisture contact, helps to maintain body heat. Furthermore, the suit’s design features a textured palm, which aids in grip and can help reduce water entry. I’d love to answer any further questions you may have, please feel free to ask! – Other customers have also found the thermal regulation of our Mares suits to be exceptional.

The Mares Extreme Undergarment is an absolute delight to wear. It’s comfortable, flexible, and provides the right amount of insulation. I’ve noticed that it does tend to lose some of its insulating properties when wet. Has the manufacturer considered adding any waterproof treatments or coatings?

What do you think about incorporating weight reduction technologies into the design to make it even more popular among freedivers and spearfishers?
Junhao Lo –
Thank you for your suggestion, Welson. We appreciate your feedback and love hearing new ideas about how to improve our products. Our designers and engineers are always looking for ways to enhance the performance and comfort of our freediving gear. However, incorporating weight reduction technologies into the design would require significant research and testing to ensure it meets our quality and safety standards. We can certainly consider it as a potential future development. Have you had any experience with weight-reducing technologies in freediving gear that you’d like to share?
