Mossy Oak Black 30oz. Double Wall Stainless Tumbler, 1 Each

I bought this on a whim after seeing so many people with the expensive stainless tumbler. I have tested this tumbler on several occasions and in varying climates. I have not tested hot liquids, as it's the summertime in Louisiana right now. However, even in 90+ degree weather, this thing maintains ice cubes and cold beverages for HOURS and HOURS! I'm really impressed. If you are looking for a smaller cup than the large 30 oz, perhaps for a younger person with smaller hands, the 20oz is a good option. But if you want a large cup to last you longer, this is a SURE BET. You will not be disappointed.

This tumbler works very well. There is no glaring difference in performance when compared to the Ozark Trail version of the same size. Only one small thing might be worth the additional $5 cost to you, the lid. The MO has a 2 piece lid that rotates to open /close the drinking slot. Might be nice if you work someplace where its likely that something could crawl or fall in your drink. On the down side, liquid migrates between the two parts, necessitating a more through and frequent cleaning. Lid does snap apart for washing. The cup is not leak proof however and must remain upright. OT has a slot that is always open and easy to clean up. BTW, the lids do not interchange. The MO is a slightly smaller. Comparing overall size - base diameter on MO is slightly larger than OT. MO= 2.90 , OT= 2.81. Less than 1/8". This could be a factor depending on your vehicles cup holder size. As well, the exterior profiles are different. The MO is about 1/2" taller than OT. As previously mentioned, the top has a smaller diameter. MO= 3.86 OT= 3.95. This small amount might be needed for side clearance if your cars cup holders are less than 4" center to center. Both work just as good as the Y brand for a lot less dough.
