Rating: Great tech for dedicated purpose
Reviewer: Jason Griffiths
3mm polytherm by lavacore i was shocked to find out how warm this material is. as great as the tech is for keeping heat in, its still a thin suit that will allow heat to be drawn out in colder waters pretty quickly. i would recommend this as either a warm or shallow (>35ft) cold water dive. theres loads of mobility for wreck dives and i hope to test it as a base layer under a glacier this winter...will this review then.

I got these to cope with oooler water (17 degrees celcius and below) to wear inside my boots and they made a huge difference! Would highly recommend any lavacore products for extra warmth underneath your wetsuit.

These dive socks will keep your feet warm even if the rest of you is cold. I wore a 3ml wetsuit in 78/79F water on a recent Caribbiean dive trip. The 3ml wet suit wan not as warm as I would have liked but my feet never got cold! Easy on, easy off.

  • cynthia:

    Is there a size 13 or 14 for men.

    Bob  (Certified Scuba Instructor at

    The sizes we list on our site are the sizes the manufacturer offers.

  • Lee:

    Would these be good for my 80+ year old mother, who is always cold, to use inside her shoeboots. Nothing to do with water sports. I was recommended to this site for this purpose. She wears a size 6.5 shoe. Thank You

    Darrick  (Certified Scuba Instructor at

    Hello Lee, yes these socks would add warmth to your mother's feet.

  • Pam:

    I wear a size 8 shoe (womens) - small or medium?

    Darrick  (Certified Scuba Instructor at

    Hello Pam, you would need a size Medium.

  • Tom:

    I plan on wearing these under my 3 ML dive boots and have a size 7.5 shoe size. Dont want to get socks that are too small but want tight fit. Should I go with SM or Med?

    Darrick  (Certified Scuba Instructor at

    Hello Tom, you want the size 7-9 (medium). If you went with the size small they would be to tight on your feet since you are a 7.5 size.

  • catherine:

    Hi I have an allergy to rubber. Is there any rubber in the material or neoprene? Also is there a bootie that has a sole like a reef walker that is polyolefin that you carry? I saw that you have a polyolefin hot sock. Can it be worn on rocks?

    Arthur  (Certified Scuba Instructor at

    Hello, there is no rubber or neoprene in this product. unfortunately there isn''t any booties that are made of this material.

Close to the skin, this soft internal fleece combined with high 4-way stretch produces the ultimate comfort / warmth / weight ratio, a true leader amongst artificial/man-made fabrics within the water sports industry. Wet or dry, hot or cold, Polytherm helps control your core temperature longer and when wet maintains neutral buoyancy, crucial to divers and any high activity watersports enthusiast.

Whether worn as a stand alone garment, under your wetsuit or even clothing, olytherm is guaranteed to keep you well insulated, flexible, lightweight and free from windchill.

Polytherm Tri-Laminate
Combining the outer shell and the inter PU layer, the fleece of Polytherm integrated ensures a very high heat and insulation rating, the PU film layer gives this combination added water resistance and high protection from windchill. Used in areas where extreme heat retention is required.

Seam Construction
All of the Lavacore seams are overlapped during flatlock sewing to ensure maximum water integrity and reduced waterflow through the seams. Maximum heat retention is therefore achieved when worn in colder water conditions. See diagram. To ensure maximum integrity and longevity of your Lavacore garment the seam cross-overs on the inside of the suit are locked under the threads of the adjoining seam. The seam construction being doubled and flat-locked allows for maximum stretch out of the four way stretch fabric technology without compromising at seam edges.

Panel Design
The Lavacore range includes female and male specific cut and unique design.
Lycra panels with contemporary lines and graphics are incorporated into all garments.
Full Under the Arm Gusset. This ensures there is no rub or irritation on the sensitive under side of the arms and side of the body. It also reduces restricted movement considerably and allows for extra reach without seam strain and damage.
