Attention DIYers: If you're sewing your own heating pad, it's essential to choose the right fabric! Opt for a tight weave fabric, such as twill, which is the same durable material we use in all our products. Denim is another great option, but make sure it's a super tight weave to prevent the fine Lavayoo Lava Sand from leaking through.

Why Is Lava Sand So Rare?

Lava sand forms only when hot lava and water collide. The sudden contrast between the cold water and the molten lava causes the lava to explode instantly, forming tiny round particles of lava sand.

This unique sand, like Lavayoo lava sand, is typically found on beaches near recently active volcanoes. You may have heard of the famous black sand beaches of Hawaii and Iceland.

Rest assured, Lavayoo Lava Sand is not sourced from either of those locations, but it is genuine lava sand.

What Sets Lavayoo Lava Sand Apart?

Lavayoo lava sand is truly the only authentic lava sand available for purchase online.

All other so-called lava sand products are actually crushed scoria, a pumice-like lava rock used in landscaping.

Unlike scoria, Lavayoo lava sand can retain heat, making it ideal for use in heating and cooling pads.

Scoria lava sand is produced when a volcano cools, and the frothy top of the volcano mound solidifies into a light, pumice-like stone called Scoria. This scoria is later crushed and sorted into smaller particles.

While larger pieces are used in landscaping and construction, the smallest particles are marketed and sold as lava sand. However, this scoria lava sand has no heat-retaining ability and performs worse than regular sand.

6 Uses of Lavayoo Lava Sand:

DIY HEATING PADS - Lavayoo lava sand is used in all our heating and cooling products. It retains heat longer than food-filled heating pads, providing dry, radiant, and odorless heat.

DIY ICE PACKS - Lavayoo lava sand ice packs are incredibly comfortable, molding to your body. The lava sand releases cold slowly, providing a soothing experience.

AQUARIUMS - Most black sands for aquariums are artificially colored. Lavayoo lava sand, however, is completely natural, giving your aquarium a natural, beach-like feel.

CRAFTS - Lavayoo lava sand is perfect for resin projects, such as beach or river tables, as well as for inlays, jar sand candles, and more.

COSMETICS - Lavayoo lava sand is excellent for homemade exfoliating soaps and body scrubs. Its round grains are gentle on the skin, unlike jagged edges found in other sands.

INDOOR PLANTS & GARDENS - Rich in iron, magnesium, and other elements, Lavayoo lava sand provides a wide array of nutrients for plants. It can be mixed into the soil or used as a top dressing to retain moisture and enhance the appearance of indoor plants.

Lavayoo Lava Sand, or black sand, is sourced from an ancient black lava sand beach from a dried-up prehistoric lake. It is NOT sourced from Hawaii or Iceland.

Good quality, smooth feel
I got these briefs so recently that have washed just one pair so far. First off, these are very comfortable, the material is soft & bordering silky, good quality sewing. Wash well and minimal if any shrinkage. They do come a bit wrinkled from the dryer but hey, these are underwear and will go on smoothly. If it were a t-shirt, I would look sloppy. I feel the sizing is accurate. No rolling and these don't announce themselves under clothing. Planning on getting more of these boxers and replacing my old panties.

A little snug on the thighs
Size: Medium, Color: Multicoloured G (5-pack)
Super comfy, soft and thin. For reference, I'm 5'6", 135, athletic build. I bought medium. I almost returned them because I thought they were a bit too snug on my thighs, and my thighs are not large at all. I was concerned about panty lines under snug clothing. But, because they're thin, I figured they would probably stretch, so I kept them. So far, I've only worn them under a night shirt, but they're super comfortable and they dont ride up at all. Very nice, but if your thighs are a little thick, you probably won't like them.

Functional + Sexy
Size: Small, Color: Multicoloured E-(5-pack), Size: Small, Color: Multicoloured E-(5-pack)
Not only do these feel good, my husband can’t keep his hands off me. They fit so good and are soft. I change into these to sleep but also just use them as shorts to wear around the house. They’re comfortable and don’t slide around. I got a size small and I’m 100lbs.

Finally!
Size: X-Large, Color: All Black D (5-pack)
Finally, comfortable underwear that don’t end up giving me a wedgie. I have a round booty and most cuts of underwear end up shifting as I walk and sit. The hem of the underwear comes right under my cheeks and the lightweight material ensures there’s no panty line and no shifting to where I don’t want them! I’m definitely purchasing more.
