This fills the void that I didn't know I needed, Keeps the coffee warm, doesn't leak on long rides.. & is a great looking lil' tumbler. It's also worth mentioning that the mug is easy enough to pop open & clean.
Watch: the Rift Tumbler rides the tailgate without a drop spilled
Your daily coffee, sealed against your commute.
Best For: Anyone whose full morning brew has to survive the bag, the bus, or the back seat.
- Lock it, toss it in your bag - VaultLoc™ twist-lock lid seals leakproof
- Hot stays hot, iced stays iced - double-wall vacuum insulation in recycled 18/8 stainless steel
- The everyday size - 473 ml (16oz) holds a full morning brew; still fits cup holders
- Carry it hands-free - the included Rift Link loop clips it to a bag or finger
- Grips without a handle - sculpted base fits your fingers; silicone bumper stops slides
- Eight colours - from Black to Alpenglow, pick yours
*Dishwasher safe - just unclip the Rift Link first.
Picture this: You brew at 7. Meeting at 8, site visit at 9. The Rift rides the whole way locked in your bag - and the coffee's still hot at 10.
The lid is the trick. Twist it and it locks like a jar - not a press-on cap that pops off between your laptop and lunch.
One tumbler, every day. Commuters, drivers, campers and desk drinkers - 473 ml is the size you reach for daily.
You've paid the spill tax. A cheap sip-lid, one hard brake, and there's a flat white in the footwell.
It grips back. The sculpted base fits your fingers, and the silicone bumper keeps it planted on console or desk.

I was looking for a quality mug. This one fits the bill. It is easy to hold and carry. It fits into the cup holder in my car. The lock top means it won't pop open and spill. And it looks good!
Great mug, lid seals well, looks great with a U of Michigan sticker. Go Blue!
I have been looking for a durable "no leak" way to take coffee on my motorcycle and did not want a thermos. This 16 oz is perfect. And my VSSL grinder even bits (mostly) in the container too!
There’s five in my family, we all have one and so far so good!
Good product the quality is awesome!
I absolutely love the tumbler!!! Camping in Wyoming and brewing local coffee daily!
Hands down my new favorite tumbler. Sleek and cleaning looking. The seal for the top holds fantastic when closed. I’m not much for coffee but I do love my energy drinks and it keeps em cold for a while.
I have seen the tumbler in ads for the longest time and finally snagged one on sale. I thought the design was great and I didn't have any expectations on the quality but I am truly impressed. The added rubber base is fantastic and easy to remove when trying to clean it. The tapered bottom is great to hold and place in cup holders but it still has a steady base for using the pour over set. The lid springs open so it doesn't flop down when trying to drink. The materials used for the actual lid and spout had a great texture so the drinking experience feels smooth and premium. The semi translucent lid helps you see if there is still liquid in the cup. The added lanyard is also an amazing touch too. I can tell a considerable amount of time and effort went into this tumbler to make it stand out from anything else I have seen or owned. Definitely worth the standard price knowing what I know now.
I have so many tumblers and like most of them so I was hesitant at first to get another one but I really liked what I was seeing and reading in their ads. So, I caved in and ordered one. Wow, the quality is exceptional and by far the best tumbler I've ever owned. Only regret is that I should've ordered the 20 oz!!!
Love the spill proof lid.
I received a 20 oz. tumbler for my birthday and I've used it everyday since then. The total leakproof cap and vault door is fantastic, so is its insulative quality but for me the very best thing is the lanyard. Iʻm recovering from an arm injury and reconstructive surgery so I am primarily using one hand, the left, for carrying most things and the lanyard makes this incredibly easy looping it around my wrist or even just a single finger which allows me to carry other things with the same hand something that was a challenge with other tumblers. Simply the best steel tumbler on the market, you should buy one!
Bought today at the overland expo and was extremely pleased. The build quality is exceptional and 100% leakproof. Even though I didn't use it for coffee
This is a customer service story as much as it is a product review. A few years ago I bought the small grinder that preceded the Java 25. It was great. One morning the small screw that attached the handle fell out and the handle came off. I called support hoping to get a new screw. Instead, I was sent a new Java 25 grinder. It works even better, faster and quieter. I was hoping for a screw and got a new grinder. It almost made me feel guilty, so I bought two Rift tumblers. We already had a cabinet full of travel tumblers and did not need two more. Now we don't need the ones we already had. The Rift tumbler is a great product. It does exactly what they say it will. No leaks, maintains temps, and it's easy to clean and drink out of. The Rift is as good a product as the Java 25, and they are both top shelf. I am a Marketing teacher, currently teaching a class called Services Marketing. This sequence of events has earned a permanent place in my list of great service examples. That list is much shorter than my lists of poor and just mediocre service. VSSL is a company doing things right. Great products backed up by great service. Sure, they are a bit expensive, but I think the quality makes them a bargin.
“This thing feels almost overbuilt—in a good way. ”
I'm very happy with these mugs, It keeps my coffee warm all day at work.
Great design that’s keeps coffee warm and spill proof too.
Feels great in the hand and this has got to be one of the best designed anti-spill caps I've seen.
So I ordered two 10oz and loved them, just realized they don’t hold enough coffee for work! So! I ordered 2 more at 16oz one for myself and one for the wife. And I love it. Love the top and its ability to seal tight.
Exactly as needed! Very pleased with every aspect of this product.
Love my tumbler. It is truly spill proof. Bought my wife one as well.
I had high hopes for this after using other VSSL products and I was not disappointed. Generous 16oz capacity, easy grip, cup holder friendly, and the leakproof lid is everything I ever wanted. I use it while camping, traveling, hiking and even in my every day use. To have the ability to have hot coffee and know it’s not going to spill out in your bag or car is amazing. I love the ability to customize the bumper too. I cannot wait to see what VSSL puts out next!
That warm golden-orange color feels like an adventure waiting. I use it all the time on the road and winter hikes. It keeps my coffee steaming hot for hours. It’s leakproof, no worries in my backpack, and easy to use and clean. Honestly, I love it.
Rugged and solidly built. The lanyard is a useful feature. Nice antislip grip at the bottom. The anti-leak takes some time to get used to but overall a solid product.
Very high quality product in appearance, form, and function. Superior materials and superior construction.
Super great tumblers it holds perfectly in my hand doesn’t slip and the opening springs loaded stays open love it
had my first coffee with my new VSSL tumbler this AM and it passed the gym bag test: I thought I’d secured it, but it ended upside down. Had zero leaks and two hours later, the coffee was still hot. Looks great, obv well designed and does exactly what it promises. V happy with this purchase.
Convenient to use. . . Tumbler fits " Great in the cup holder in my cars. Keeps drinks cold & hot !!!" Will be taking it with me for a majority of my fluids to hydrate !!!
I love my tumbler and use it when I hike and snowshoe. It really keeps the beverages warm and is lightweight!! Thank you
After several tries to find a tumbler that is easy to hold, fits in my car cup holder, keeps my coffee hot, no leaks, and easy to clean lid, I love my VSSL Rift Tumbler.
Just got this tumbler as a gift and it’s perfect!!! It has a leak proof top & fits perfectly in my car’s cup holder.
I just received a rif tumbler as a gift and I love it. The strap is so convenient for carrying, especially if you have many things in your hands. Since it’s leakproof, there’s no need to worry about spills. Finally, the twist-lock lid keeps the mouth piece sanitary in between sips. All in all it’s a wonderful product.
Great seal! Great size for car and the rubber bottom really holds it in place! I love the way the spill proof top goes over the sip attachment. Looks cool too…I get a lot of inquires at the dog park about it.
What a great gift idea! I received a Rift Tumbler recently and am super impressed. It's going to stay with me for the daily commute as well as the camping trips.
Awesome rugged mug. Love it
This is an excellent coffee cup. My coffee stays hot all morning and I the leak proof lid keeps my gym clothes and work clothes free from coffee stains.
Very nice
I was pleasantly surprised. There are so many stainless cups out today, but I appreciate the features the Rift tumbler offers. The strap to hold the cup is so convenient. It makes it easy to strap on or hold without feeling bulky. The textured outside of the tumbler along with the rubber bottom allows for good grip. The spout stays in an open position when not locked, I like that because if the spout is closed, I know it’s locked and won’t spill.
Well designed, and great quality. Rugged enough to handle your everyday on the go adventures. I highly recommend
Hella dope! This has turned into my emotional support mug. I never worry about it spilling when it gets knocked over, it keeps my coffee warm almost all day 😳😮💨 and honestly is the coolest steel mug I’ve ever had. I want to grab a 10 oz to keep at work next.
