As parents, we love these SIGG 0.4L water bottles because they"re leak-proof, safe and portable with cool designs. The bottle"s special liner ensures great taste and is tested to prove 0% leaching. The small 0.4L and 0.6L sizes easily pack into backpacks or lunchboxes. Kids go crazy for the fun and colorful designs! Many of these cool styles are discontinued each year - see one you like, don"t wait! Consider getting a bottle sleeve to protect and insulate your SIGG bottle (if dropped they can dent). You can also customize your SIGG bottle with a variety of accessories, including colorful SIGG caps.
