Stainless Steel Thermos
Most of the wide mouth thermoses on the market right now are designed with stainless steel on the exterior. This gives the thermos an appealing style and helps seal in heat even more effectively. Also, stainless steel is more durable and will not crack or break the way some cheaper made plastic thermos may do.
You can find Stainless Steel Wide Mouth Thermos from all of the top brands, including Stanley and the original Thermos brand.
