Rating: Needs More Ballroom For Men
Reviewer: Andrew T.
got size ml based on the size chart. have the short-sleeve top in l because ml was too smallso i was nervous to get ml shorts. fit is a little too snug but ok. bigger issue is they need more space in the crotch area for me (a man). "unisex" ? i dont think so. would stretch and work well for women as long as their hips arent too wide. used them once so far, in 77 degree f saltwater and they worked very well. i rinsed them after use and hung to dry in the bathroom (no breeze). didnt dry completely in 48 hours and had to put them in a plastic bag in my suitcase. unfortunately it took 2 days to get home and they smelled of milldew when i got home. my fault, but maybe something can be done - or just advice to other users.

Reviewer: William Smith
i am allergic to neoprene, so i need something between me and my wetsuit. i got the shorts and top and i like themcomfortable, but i do wear a wetsuit over that to keep warm enough. in warm water the lavacore would be enough, but in cooler water (74-76) i am a pussy and want more warmth. seems to be well made

    I am going free diving in the Bahamas in a week. Looking for free diving gear that will work in warm water. I was thinking of these shorts with a camo long sleeve rash guard? What do you think. Also my waist is about a 33, what size shorts?

  • Diane:

    I have several auto immune conditions that require me to stay completely dry in my genital area. Is there anything out there that is not a complete head to toe suit that will meet my needs? My female area must stay free from outside bacteria and I love the water. That is one reason I live in Florida. Please help

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.

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.
