The Therm Hydracloud features a full waterproof (hydra) and windproof outer combined with ultra-soft cloud-like comfort. Providing midweight warmth and protection in wind, rain and snow, and lined with soft-touch jersey mesh for a cosy feel inside. And when the puffer gets wet, a secret pattern is revealed! See the SplashMagic pattern appear in the rain then disappear again when dry. Fun for toddler and big kids alike!
