Apart from leaks, most other insulated mugs are very large considering the amount of hot or cold drink within. HydroFlask have completely changed the game with this insulted flask as it doesn't leak at all even when you turn it upside down! It also solves the size issue by being very small, more in line with the size of the contents. This also helps it to fit under the spouts of our coffee machine. The good news is that the size isn't at the expense of performance as the contents are kept hot for hours. I've found tea in particular stays hot for a long time. Travelling to a venue to watch some sport and having a hot drink for the duration is absolutely achievable. A points to bear in mind is that assembly and disassembly of the lid section can require some strength and so would not perhaps suit people with strength issues. Also, the red silicone seal needs to be fitted the correct way round (match the lid moulding with the cut outs on the seal) during reassembly as other wise this leak proof flask will leak! Personally, I think this flask is completely worth the cost for the high quality of the item. It's literally a game changer 😀 Review: No leaks, keeps drinks hot and looks great. - Best coffee flask I've bought to date. No leaks, and easy to carry. I have a pile of useless travel cups in the cupboard. This is the first one I've been able to consistently use. It's easy to wash as the lid comes apart. It also keeps my drink hot for hours which is handy when you work in the NHS as I never get to finish a cup of tea. Highly recommend. ## Features - DESIGNED FOR HOT DRINKS: The Hydro Flask 12 oz (355 ml) Wide Mouth Bottle with Flex Sip Lid is perfect for coffee, tea, or your favorite beverage on the go. - IDEAL TEMPERATURE CONTROL: TempShield double-wall vacuum insulation keeps drinks cold for up to 24 hours and hot for up to 12 hours, with no condensation. - LEAKPROOF WHEN CLOSED: Flex Sip Lid seals securely for worry-free transport, making it reliable for commuting and travel. - DURABLE STAINLESS STEEL: Built from high-quality stainless steel for long-lasting performance; dishwasher safe for easy cleaning. - CUPHOLDER COMPATIBLE: Designed to fit most car cupholders, with a wide mouth opening that accommodates ice cubes for added versatility. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0DG34JMPK | | Age Range Description | Adult | | Age range (description) | Adult | | Best Sellers Rank | 21,044 in Home & Kitchen ( See Top 100 in Home & Kitchen ) 153 in Insulated Bottles | | Brand | Hydro Flask | | Brand Name | Hydro Flask | | Cap Type | Flex Cap | | Capacity | 591 Millilitres | | Colour | Birch | | Country Of Origin | China | | Customer Reviews | 4.3 out of 5 stars 5,841 Reviews | | Is Oven Safe | No | | Is the item dishwasher safe? | No | | Is the item microwaveable? | No | | Item Dimensions W x H | 7.4W x 27.3H centimetres | | Item Type Name | Coffee Flask | | Item Weight | 0.37 Kilograms | | Manufacturer | Hydro Flask | | Material Type | Stainless Steel | | Model Name | Wide Mouth Flex Sip Lid Flask | | Number of Items | 1 | | Pattern | Surf | | Product Care Instructions | Hand Wash Only | | Recommended Uses For Product | beverages | | Recommended uses for product | beverages | | Special Features | Double Wall | | Special feature | Double Wall | | UPC | 840394204628 | | Unit Count | 1.0 count | | With Lid | Yes | ## Product Details - **Brand:** Hydro Flask - **Capacity:** 20 Fluid Ounces - **Colour:** Birch - **Recommended uses for product:** beverages - **Special feature:** Double Wall ## Images ![HYDRO FLASK - Coffee Flask 591 ml (20 oz) - Vacuum Insulated Stainless Steel Travel Mug with Leak Proof Flex Sip Lid - Wide Mouth - Birch - Image 1](https://m.media-amazon.com/images/I/510HYohJhyL.jpg) ![HYDRO FLASK - Coffee Flask 591 ml (20 oz) - Vacuum Insulated Stainless Steel Travel Mug with Leak Proof Flex Sip Lid - Wide Mouth - Birch - Image 2](https://m.media-amazon.com/images/I/717qChy6VZL.jpg) ![HYDRO FLASK - Coffee Flask 591 ml (20 oz) - Vacuum Insulated Stainless Steel Travel Mug with Leak Proof Flex Sip Lid - Wide Mouth - Birch - Image 3](https://m.media-amazon.com/images/I/61vhtsPCW4L.jpg) ![HYDRO FLASK - Coffee Flask 591 ml (20 oz) - Vacuum Insulated Stainless Steel Travel Mug with Leak Proof Flex Sip Lid - Wide Mouth - Birch - Image 4](https://m.media-amazon.com/images/I/81mRcZ1pBKL.jpg) ![HYDRO FLASK - Coffee Flask 591 ml (20 oz) - Vacuum Insulated Stainless Steel Travel Mug with Leak Proof Flex Sip Lid - Wide Mouth - Birch - Image 5](https://m.media-amazon.com/images/I/71iPyKY8tpL.jpg) ## Available Options This product comes in different **Color, Size** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Outstanding and no leaks! *by S***S on 14 September 2024* I've used various insulated coffee mugs over the years and all of them have had the same problem - leaks.
