When comfort, hydration, and staying power matter most, Sliquid Tsunami delivers. This ultra-thick water-based gel is specially formulated for those seeking long-lasting lubrication and enhanced moisture, making it an excellent choice for sensitive skin, vaginal dryness, perimenopause, menopause, post-surgical recovery, pelvic floor therapy, and intimate wellness support.

Powered by carrageenan, a naturally moisturizing seaweed extract, and an increased concentration of plant cellulose, Tsunami creates a luxuriously thick texture that stays exactly where you apply it. The rich gel consistency provides exceptional cushioning and glide while helping support healthy tissue hydration and comfort. Unlike thinner lubricants that quickly run or absorb, Tsunami offers prolonged moisture and slip for extended intimate sessions and therapeutic use.

Its body-friendly formula is pH balanced, hypoallergenic, non-toxic, and free from glycerin and parabens. Safe with condoms and all intimate devices, Tsunami is designed to work in harmony with your body while providing the extra hydration and comfort many people need.
