These 100% Chillproof longpants are equally suitable teamed up with a Sharkskin top, under a Drysuit, or under drypants for kayaking. They are cut with a high rear waist for comfort and warmth, provide protection from chafing when dry, and provide peace of mind knowing that if you do get wet you will still be warm. Chillproof longpants can be worn in combination with all other Sharkskin tops.

About Chillproof

Chillproof is an aquatic specific windchill proof, 3-layer composite material with the thermal properties of a 2.5 to 3mm neoprene wetsuit but without many of the drawbacks of traditional wetsuits. Chillproof can be worn under a wetsuit for extra warmth and enhanced wind protection. Chillproof can also be worn by itself as the perfect watersports thermal wear or layered with other Sharkskin garments for extra warmth and insulation.

It is ideal for scuba diving and snorkelling, jet skiing, paddle watersports, board watersports, wind watersports, sailing and many other watersports.

Chillproof Features

  • Nylon/Spandex outer layer for superior durability and abrasion resistance.
  • 100% windproof and 10K+ breathable membrane to stop windchill to keep you warm yet regulate body temperature to avoid overheating.
  • Hollow fibre 'next to skin' fleece for warmth, comfort and superior moisture wicking properties.
  • Durable water repellent (DWR) finish to provide a protective shell that ‘sheds’ water.
  • 4-way stretch ensures garments are non-restrictive allowing a full range of movement and are easy to get on and off.
  • Non-chaffing, itch and odour resistant properties mean that garments can be worn for long periods of time.
  • Durable seam thread to resist deterioration in saltwater so the garment will last longer.
  • Neutrally buoyant so there is no need to add extra weight when diving.
  • UPF50+ for sun protection.

    Good under a summer wettie for winter dives

    Wore these along with the top, under a 3 mm closed-cell neoprene wet suit. Free diving for scallops where the water was 12 degrees C in Port Phillip Bay and I managed at least 2 hours. When I jumped out I didn't even have numb fingers and toes :)

    Used the same 7 kg weight-belt I wear with the wet suit plus 1 extra weight. TBH I could probably have managed without the extra weight.

    Chillproof long pants - like a second skin

    Enough elasticity, thus fits well. Good quality. Good thermal insulation, but a little doubtful that it’s equivalent to a 3mm wet suit
