SIGG Helia Optimistic Yellow 0.45 L

This vacuum-insulated, 18/8 stainless steel mug is designed to make your drinking experience as easy and enjoyable as possible. It's sturdy enough for any adventure while preserving the flavor and aroma of your beverage to ensure every sip is perfectly refreshing.

The double-wall construction keeps your iced tea, cocktail or smoothie at the optimal temperature and ensures that the outer wall of the mug doesn't sweat. Cold drinks stay cool for 17 hours, while hot drinks can last 3 hours before losing their heat. The Helia also comes with a handy durable glass straw and cleaning brush, so you can avoid single-use plastic straws altogether.

And you can rest assured that, like all SIGG products, it is designed with sustainability and food safety as a top priority, meaning it is both recyclable and free from harmful chemicals like BPA.
