Fellow 10 oz Rocky Lowball Tumbler - Insulated Stainless Steel Whiskey and Cocktail Tumbler with Ceramic Interior and Swivel Pebble Lid (Matte Black)

This is my favorite to-go coffee mug I've ever had. Fits great in car cup holders, keeps coffee plenty hot for how long it takes to drink 10oz, and has a great design. Ceramic interior helps keep coffee tasting good. It's splash-proof, which is all I need for morning commutes and at my desk. I see people complain that it's not spill-proof, and it definitely isn't, but they are pretty clear with that in the marketing. If you enjoy dumping your coffee cups upside down, then yeah, this mug isn't for you, but besides that it is an amazing cup. 10/10. I've bought 2.

I recently picked up the Fellow 10 oz Rocky Lowball Tumbler, and it has quickly become my go-to glass for all my whiskey and cocktail moments. The first thing that struck me is how sleek and modern it looks – the stainless steel finish gives it a premium feel, and it fits comfortably in my hand. It’s the perfect size for a neat pour or a cocktail on the rocks. What really stands out is the insulation. Whether it’s whiskey or an Old Fashioned, this tumbler keeps my drinks perfectly chilled without diluting them too fast. The double-walled design prevents any condensation, meaning no more annoying coaster use! It also works surprisingly well for hot drinks if you want a quick coffee or tea. The build quality is solid – you can tell this tumbler is made to last. It’s durable enough for outdoor use (no worries about breaking glass!), and it has held up well after multiple washes. The versatility and thoughtful design really make it stand out from other drinkware I’ve used. If you’re into whiskey, cocktails, or just enjoy a stylish tumbler that keeps your drinks at the perfect temperature, this Fellow Rocky Lowball is a game-changer. Highly recommend!

I am absolutely loving these Fellow Rocky Lowball Tumblers! The magnetic swivel tops are a total game-changer—so smooth and satisfying to open and close. I actually did a video demo to show just how cool they are. The ceramic interior means no metallic taste, and the matte black finish is just gorgeous. They keep my drinks perfectly chilled, and they’ve got a solid, quality feel to them. If you’re looking for a sleek and functional tumbler, these are it. Let me know if you have any questions. Cheers

The Fellow 10oz Rocky Lowball Tumbler is the perfect size to take with me on-the-go and is available in three color options. This tumbler is easy to clean, dishwasher safe, easy to hold and fits in my car cup holder. It keeps my drinks cold or hot for a great amount of time; insulation is on point. I like the swivel lid, and it comes off with ease when you’re ready to wash it. I use this tumbler almost daily and love the quality! I definitely think the price point is perfect as well. I highly recommend this tumbler!

It’s Very light weight compared to other tumblers. The color is super white and easy to clean. It seems very durable as it is completely insulated. It Keeps drinks hot for about 2 hours. It’s Perfect for busy moms who always have to warm their coffee. The swivel nozzle is very convenient to keep dirt and degree out.

I gave this to my uncle as a Christmas gift and this is so cute. It’s like the perfect amount for a cup of coffee. It’s super secure and it closes great. There’s no leaking and the size is way larger than you expected because it’s super round. The durability is amazing. The qualities is great and it looks super fancy and cute. It’s super convenient.

Feels premium. Drinking without the lid is awesome as flavor stays perfect. Temperature is held as advertised. Comfortable size to hold. Not leak proof, tilting the cup too far leaks liquid, but it's much better than spilling your whole drink. I love to brew directly into this but it stays rather hot. I suggest cooling the drink to your preferred temperature before putting it in (Try a hyper chiller!)

Another Fellow failure, to which I was duped once again. Coffe stays warm maaaybe 20 min. Lid looks as if a bloodhound drooled all over after three sips. Staring to wonder if they spend one second testing their products before trying to suck you in. Looks ok, but far from functional.

Coffe tastes better and stays hot!

Absolutely brilliant coffee cup and sips very well. Works really well. Keeps a good temperature for an hour. No other material taste, only great specialty coffee taste. I actually think it’s worth the money as I know if taken care of, will last a very long time..

It keeps it hot for about 3 hours which is plenty of time for me to finish my morning coffee

Love all our fellow stuff, amazing quality and the black doesn’t chip off !

Love my mug
