Insulating neoprene construction: quality neoprene provides thermal protection to keep champagne, wine or other beverages chilled or warmly insulated for extended periods. The material is flexible and durable for repeated use. Protection and stability: Sturdy, finely stitched construction and a stable base help protect bottles from breakage and damage during transport. This design also works well as a baby bottle cooler bag solution when you need safe, insulated storage for infant bottles. Universal fit and nonslip design: Stretchable neoprene conforms to most standard bottles up to 11.5 cm in diameter and 36 cm in height, creating a secure, nonslip wine bottle cooler experience for a variety of bottle shapes. Portable, waterproof and spacesaving: Lightweight, compact neoprene tote with a practical carry handle. The waterproof material helps guard against spills, and the bag folds almost flat for convenient storage and travel. Ideal as a picnic beverage holder or a travel bottle carrier. Use scenarios: Picnic or outdoor dining: Carry chilled wine or champagne to a park or beach; the bag keeps the bottle insulated and protects it during transport. Travel and commuting: Bring a single bottle on overnight trips or to a gathering without adding bulk; folds flat when not in use. Baby outings or daycare: Use as a baby bottle cooler bag to keep infant bottles insulated and protected while on the go. Practical, reliable and easy to store — a compact insulated solution for wine, champagne, other drinks and baby bottles.
