Product Description

Color: Black

The Thermos brand is well known as the quality and performance leader in insulated food and beverage products. The Sipp line is our newest series of insulated beverage containers that mixes fashion with function. By using a Sipp product instead of a disposable cup, you can help the environment without compromising style.

Why Thermos?

An ideal choice for people on the go, the Sipp Vacuum Insulated Travel Tumbler is built to last and loaded with features to make for a more enjoyable drinking experience. Thermos vacuum insulation technology virtually eliminates temperature change within the beverage container by creating an airless space between two stainless steel walls. The result is an insulation layer that performs better than any other. A superior insulated container you can depend on to keep your beverages hotter, colder, fresher, longer. This travel tumbler keeps beverages hot for 5 hours or cold for 9, making it a great choice for long days out and about or in the office.

Features and Benefits

Constructed with double wall stainless steel, this 16 ounce travel tumbler is virtually unbreakable, yet its sleek design is both eye-catching and functional. It is also dishwasher safe for easy care and use.

For tea drinkers, a built-in tea hook is just the ticket to brew tea on the go. The tea hook can also accommodate most loose leaf infusers.

Leak-Proof and Worry-Free

The Sipp Travel Tumbler comes equipped with a leak-proof lid that operates with the push of a button. The lid is made of BPA-free Eastman Tritain copolymer which resists staining and provides durability. And because of the double wall insulation, the stainless steel body stays cool to the touch with hot beverages and condensation-free with cold beverages.

Recommended Tip for Maximum Beverage Enjoyment

In order to maximize the incredible insulation technology, it is recommended to either pre-chill or pre-heat the travel tumbler just prior to use. This can be accomplished by filling the tumbler with cold or hot tap water, attaching the lid and letting it rest for a few minutes. Before you are ready to use, simply empty the water and fill with your favorite beverage. Attaching the lid will further increase the thermal efficiency.

The Sipp Vacuum Insulated Travel Tumbler is made of BPA-free materials and is backed by a five-year limited warranty.

Highlights

• Insulated: Keeps hot for 5 hours or cold for 9 hours with Thermos vacuum insulation technology
• Durable: Unbreakable stainless steel interior and exterior
• High Quality Materials: 100% BPA-free
• Capacity: 16 ounce

5.0 out of 5 stars Excellent Travel mug July 1, 2010

By Sam R. Elmore

Color Name:Black

I bought this tumbler for my girlfriend. When I got it home; I opened it and poured in water from the teakettle. Using a instant read food thermometer I checked the temp. I started at 206 deg, closed the lid and let it set. at 1 hour the temp was 193 deg. At 2 hours 182 deg; at 4 hours 164 deg; and at 6 hours temp was still 152 degrees. over a 6 hours period the temp only decreased 54 degrees. During my test I noticed that the outside of the cup did not feel at all warm to the touch; the only part that changed at all was the top and then only slightly warmer. I also tested the seal by turning the cup upside down for one of the hours with no leaks at all.

I do recommend that you don't put liquid that is too hot in it expecting it to cool down to drinking level on the way to work. you won't get anything to drink.

4.0 out of 5 stars Leak proof, keeps real hot July 13, 2010

By S. Kit

Color Name:Black|Amazon Verified Purchase

Sipp is the latest tumbler from Thermos & has several improvements over my Thermos Nissan 14-Oz Stainless-Steel Travel Tumbler. Although the Sipp is good, there are some small cons.

PROS:
1. Keeps drinks hot
Thermos Sipp keeps my coffee piping hot at the office (which is air conditioned) much longer then the Nissan tumbler. Drink is really hot after 4 - 5 hours even with button in open position. Drinks in the Thermos Nissan would be lukewarm by then. As other reviewers have said, be careful not to have drinks too hot or risk a scalded tongue.

2. Leak proof
New mechanism and seals makes the Sipp leak proof when button is in closed position. It will not leak when held upside down (great for traveling). Thermos Nissan has to be kept upright as it is not leak proof.

3. Holds more drink, Fits my car
I love the bigger capacity of 16oz. Slim design fits cup holder in my car.

4. Easy to clean
Mechanism is easy to take apart and clean. Unlike the Nissan lid which traps gunk in the corners and beneath the rubber rim.

CONS
1. Seals
Two soft seals in mechanism ensure no leaks. However I'm not sure how long these will last. Thermos has not replied to my enquiry about replacement seals. Tumbler will still be useable, but not leak proof without the soft seals.

2. Where to drink from
Two slit openings on the inside depressed section allow liquid out. Because there is no handle, there is no tactile reference point when the tumbler is picked up as to where to drink from. That may be why a reviewer had problems with spillage. I get around this by referencing the plastic label on the mug wall which I line up with the drink slit when putting the lid on.... With the Thermos Nissan, the lever is the physical reference so I can pick it up & know where to drink from without looking (eg: when reading documents).

The Sipp has many great features & I'm very pleased with it. It is a worthy successor to my Thermos Nissan which is still good after more than 5 years of faithful service. However I gave Sipp 4 stars because of the uncertainty of getting replacement seals (at the time of this review). Read more ›

5.0 out of 5 stars great mug March 30, 2010

By david austin

Color Name:Black|Amazon Verified Purchase

I noticed that this was coming out when I was shopping for mugs a couple of months ago, so I kept checking back until it was released, and I'm glad I did. I had ended up with the Contigo mug before, which was OK, but I never really liked the styling. This mug is at least as good as the Contigo, and is able to be completely disassembled, so those that were worried about the build up in the mechanisms of the Contigo don't need to have that concern here.

Really the only downside of this mug is that to fit the disassembling seals, it is a couple inches taller than most mugs are, being only slightly shorter than an average 20 oz. bottle. The size doesn't bother me, and the sealing mechanism is good enough that even with the mug in the open position (you press down on the middle button, and it will snap in an open position) I'm still almost burning my tongue on my coffee 2 hours later.

Highly recommended!

5.0 out of 5 stars Great commuter mug! February 22, 2011

By R. Lau

Color Name:White|Amazon Verified Purchase

I am a Chicago commuter and a maturing coffee addict. Since our public trans system can be extremely crowded, I needed the following characteristics:

~Easy to hold (1 arm is usually propping myself up) & aesthetically pleasing (my girly side)
~Leak/spill proof
~Opens/closes with one motion
~Stainless steel
~Retains heat/cold temperature
~ALL components can be cleaned

I paid $23. Not bad considering it held up to all my requirements. I've received many compliments on its look/style, it absolutely doesn't leak/spill, bought my coffee this morning at 8am- it's now 1:30pm and STILL warm! Mind you, it's very cold and windy today! Since I need caffeine throughout the day, this allows me to sip leisurely.

I spent a lot of time researching and found that even though Contigo's are popular, black crustiness builds in the lids b/c they cannot be taken apart. Since coffee contains dairy products, it *NEEDS* to be cleaned thoroughly-- pls do not overlook this important feature! I must say, assembling it after the 1st wash was a bit frustrating, but I'm sure it'll get easier the more I use/wash it. Stainless steel doesn't affect the flavor of your beverage. This is also a factor most people tend to overlook. Plastic is less expensive, however, will not insulate your drink. This particular travel mug is well worth the $23, it's the commuter's dream come true!

PS- If there was one thing I would add to the mug... it'd be a rubber slip proof sleeve. But no biggie!

5.0 out of 5 stars All you need! July 21, 2010

By Tia

I was skeptical to say the least and couldn't understand why a cup would cost so much. I had tried many other brands but still could't find a cup that would keep my coffee hot for more than 2 hours. This Thermos brand promised it would keep liquids hot for 5 hours. I filled this cup with hot coffee at 7:30am and it was still hot after 1:30 pm! I have not tried cold liquids but I'm sure that it meets the promised 9 hours. If you want a cup that really keeps your liquids hot and doesn't spill-this is the one...don't waste your money or coffee on anyting else!
