SIISSU IN 3 LEVELS
Level 1

Familiarization

“Helps feel safe, gain confidence and comfort in the water.”
Level 1
@siissu_oficial Siissu dispone de tres niveles de progresión el cual lo hace un bañador único, innovador y adaptado a cualquier nivel que tengan los peques. NIVEL 1:Familiarización 😃 En este primer nivel se colocarán las 5 planchas para ofrecer una mayor seguridad dentro del agua eliminando el miedo 😧 y acelerando así su adaptación al medio acuático. Los objetivos a conseguir en esta fase son los siguientes: - Pérdida del miedo - Familiarización con la horizontalidad - Obtención de equilibrio - Confianza - Resistencia Aquí os dejamos también ejercicios prácticos que podéis hacer desde casa. Una vez superados estos objetivos pasaremos al siguiente nivel 💪🏽 #siissu #revolucion #swimsuit #fase1 #kids #summer #fyp #natacioninfantil #swimwear ♬ FEEL THE GROOVE - Queens Road, Fabian Graetz
Level 2

Floating and Propulsion

“Approaches correct position, gaining more strength and resistance.”
Level 2
@siissu_oficial En este nivel, retiraremos 2 planchas delanteras. Conseguimos que el niño/a gane más fuerza en las piernas y que vaya teniendo más horizontalidad en el nado. #siissu #revolucion #swimsuit #fase2 #kids #fyp #natacioninfantil #padresprimerizos ♬ One Side - Iyanya
Level 3

Water Autonomy

“Will gain greater independence in the water, achieving water autonomy.”
Level 3
@siissu_oficial Hola a todos/as. En esta última fase, el niño trabajará con tan solo una plancha. Así pues, tendrá que esforzarse aún más, ganando más fuerza y resistencia y teniendo más horizontalidad.🤟🏾 #siissu #revolucion #fase3 #kids #fyp #natacioninfantil ♬ FEEL THE GROOVE - Queens Road, Fabian Graetz

After more than 30 years teaching children to swim, I’ve found a tool that truly supports learning: helping kids improve aquatic skills in a simple, fast, and fun way.

Aside from the amazing design, my son swims with incredible ease. He never felt comfortable with floaties. Siissu gives him full safety — and gives me peace of mind seeing him swim with confidence and joy.

I used to use pool noodles in my lessons, but with siissu everything is better. The float panels provide the right buoyancy and can be adjusted for progressive learning. It’s by far the most effective, safe, and simple method for kids to learn how to swim.

Since my son started swimming with siissu, I’ve been thrilled. He enjoys swimming lessons like never before, and being calmer in the water helps him learn faster. He won’t stop playing with his siissus. I recommend it 100%
