Thoughtful by design. Free by nature.
The fabric
Soft by nature.
Smart by design.
Over the past five years, we’ve refined our towel fabric through three upgrades, working towards a balance of lightweight comfort and absorbency. Along the way, we’ve improved how the hidden zip pocket is sewn into the towel, with water resistance in mind.
Every refinement comes back to the idea that started Sumoii: carry less, feel carefree and connect with nature.
Whether you’re walking down from your hotel or driving to the coast, the little things still need a place. Our hidden, water-resistant zip pocket gives your room card, car keys or small wallet a home in your towel, so a simple beach visit doesn’t need a separate bag just for your essentials.
Meet the Sumoii Sand-Free Beach Towel 3.0. Refined for 2026. Move lighter. Live freer. Find your natural rhythm.
01 / Sand free
Leave the Beach
at the Beach.
Sumoii’s microfibre releases sand easily. Give your towel a shake before you pack up, and bring home the memories of the day.
02 / Full size. Small footprint.
Stretch Out.
Then Pack Light.
At 180 × 80 cm, there’s room to settle in on the sand. When it’s time to move, the towel folds down into its travel pouch and slips into your beach tote or weekend bag.
03 / Quick drying
Ready for
the Next Swim.
Quick-drying microfibre makes it easier to move between a dip, a rest and the journey home. Spread your towel out after use and let the air do its work.
Drying time varies with airflow, weather and how wet the towel is.
04 / Soft & absorbent
A Soft Landing
After the Water.
Absorbent microfibre helps dry you off after a swim, with a soft feel against your skin and a light, compact finish that’s easy to carry.
05 / Water-resistant zip pocket
A Place for
Your Little Essentials.
A discreet zipped corner pocket gives your phone, keys and other small essentials a place to stay together while you relax.
Water-resistant protection is intended for splashes. Keep valuables out of the water and close the zip fully.
06 / Corner sand pockets
Settle in.
Stay a Little Longer.
Fill the three smaller corner pockets with sand to help hold your towel in place on breezy days. Empty them when you’re ready to go, give the towel a shake, and pack up.
A few useful details
Before You Head Out.
What is the towel made from?
Sumoii uses soft, absorbent microfibre designed to release sand, dry quickly and fold compactly for travel.
Is the zipped pocket waterproof?
The pocket is water resistant. Use it to keep small essentials together and help protect them from splashes; it is not intended for submersion.
How do the sand pockets work?
Add sand to the three smaller corner pockets to help weigh down the towel. Empty the pockets before folding it away.
How should I care for my towel?
Empty the pockets and shake off sand before washing. Follow the care label on your towel, and allow it to dry fully before storing it in its pouch.
