Double vacuum protected to keep cold drinks cold and hot drinks hot, this Wide Mouth Flex Sip Lid flask by Hydroflask is lined with stainless steel for a purer taste. Sized to fit under most brewing machines so you can fill up and go at home or minimise paper cup waste at the coffee shop, it comes with a leak proof lid and attaching strap for ease of transport. The soft-touch exterior is tactile and grippy, plus it's dishwasher safe for ultimate convenience. Ideal for gifting.
