SF TECH Sweater Polartec

SF Tech Polartec Sweater

The Polartec SF TECH top is the ultimate technical garment to wear under your drysuit. For real comfort in cold water!

It can be used as a classic warm garment or transformed into an active heated sweater in seconds. The Polartec SF TECH top is specially designed to discreetly integrate the SF TECH heating system (pads and wiring) thanks to a specific lining.

The heating elements are held perfectly in place by Velcro strips, while remaining easy to remove for washing.

It fits your body perfectly without creating any annoying extra bulk under your drysuit. The back is longer to cover your lower back even when you lean forward, and thumb holes keep the sleeves in place.

It is the perfect complement to the Polartec SF TECH leggings for complete thermal protection to wear under your dry suit.

🤿 Diveavenue's expert opinion on the Polartec top

This SF Tech top is like a second skin. What I like about it is its ability to wick away perspiration before diving, preventing that cold, damp feeling once you're underwater. Its cut is so well designed that you forget you're wearing it under a dry suit or even a hiking jacket. It's a durable, high-performance and incredibly versatile garment.

❓ Frequently asked questions (FAQ)

Can this top replace a traditional undersuit ? It is ideal as a thermal base layer or as a main garment under a dry suit in temperate waters. For very cold waters, it can be supplemented with an additional layer.

Is it easy to care for after a day at sea ? Yes, its Polartec composition is designed to withstand frequent use. As with any technical fabric, we recommend regular rinsing and air drying to preserve its insulating properties.

How do I choose my size for maximum effectiveness ? For optimal heat transfer, the top should be worn close to the body without compressing it. Consult our size guide to find the perfect fit from our range of sizes from S to 3XL.
