850ml durable stainless steel bottles with vacuum insulation and a diameter of 8.6cm (it fits in most backpack side pockets). The bottle is designed to keep liquids cold for 24 hours or hot for 12 hours and is 100% leak proof. The reinforced structural ribs on the body give strength and improved grip and the wider than average diameter makes it more stable on rough surfaces. Presented in an individual giftbox.
