weskiii Inc. (Head Office: Minato-ku, Tokyo https://weskiii.com/pages/corporate ), the operator of Australian-origin sleeping wear brand "ergoPouch", will launch limited edition new colors for the "New Sleep Suit", ideal for babies starting to walk, and the ever-popular "Cocoon Swaddle Bag" simultaneously on July 3, 2026 (Fri) on the ergoPouch official website and at select specialty stores nationwide. For the first few years of a baby's life, creating a healthy sleep environment is a major challenge for the well-being of the entire family. Japan's summer, in particular, is hot and humid, often leading to babies crying at night due to discomfort or suffering from skin issues like heat rash. ergoPouch offers sleeping wear that creates a safe and comfortable sleep environment by selecting clothing thickness (TOG rating) appropriate for the room temperature, eliminating the need for blankets. ● "0.2 TOG" to Relieve Summer Sleeplessness The new sleep suits and swaddle bags feature "0.2 TOG", ideal for summer room temperatures (recommended: 22-26°C). Made from high-quality organic cotton with excellent breathability and moisture-wicking properties, they gently support body temperature regulation for babies who sweat a lot. ● "Limited Edition Colors" to Brighten the Season The popular Cocoon Swaddle Bag is now joined by premium, limited edition colors available only for a short time. With a special design that catches the eye at home or on social media, these are perfect for personal use as well as for baby showers and summer gifts. ■ Product Details Sleep Suit Bag 0.2 TOG ● Sleeper for babies & kids from 8 months to walking stage ・Product Name: Jersey Sleep Suit Bag ・Colors: Daisies, Dragonflies ・Price: ¥9,680 (tax included) ・Material: Outer/Lining 100% Organic Cotton, Filling 100% Organic Cotton ・Fabric Thickness (TOG): 0.2 TOG (Recommended Room Temp: 22-26°C) ・Sizes: 8-24M/2-4Y, etc. ・Target Age: From approx. 8 months to 4 years old ・Collection Page: [https://ergopouch
