The Mares Comfort Mid Base Layer 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.

Key Features
- Moisture-wicking lining: Pulls sweat away from skin, keeping you dry and comfortable between dives.

- Flatlock stitching: Lies flat against the skin – no pressure points or irritation on long dives.
Suited for Malaysian Dive Sites
The Mares Comfort Mid Base Layer 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 Comfort Mid Base Layer 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’ve been wearing the Mares Comfort Mid Base Layer for a few weeks now and I’m really impressed with its durability and comfort. However, the only drawback is that it tends to lose its shape after a few washes. Overall, it’s still worth the investment for the benefits it provides.
