ComfortSIP is a 3-walled vacuum insulated travel mug designed to be the essential choice for all hot beverage lovers. ComfortSIP quickly drops scalding hot beverages to your ideal drinking temperature and then holds that zone for upwards of 4 hours. Say goodbye to waiting, ice cubes, and burnt tongues!

ComfortSIP’s flavor optimizing and temperature control features make it the best heat regulating travel mug on the market today! Enjoy ComfortSIP’s features without pesky charging cords or hot plates. For less than half the price of competitors, ComfortSIP brings you the best way to enjoy your hot/cold beverages!

ComfortSIP’s 360° Lid is designed to be drank from any direction. Fitted with a leak- proof twist lock, ComfortSIP’s 360° ComfortFLOW lid makes drinking easy and convenient for people who are on the go.

Powder Painted Exterior, Anti–Slip Silicone Sleeve, and Sure–Grip Rubber Base protect the ComfortSIP from scratches, fall damage, and beverage stains. 

The Silicone Sleeve on the ComfortSIP ensures a secure grip even when wet, offering ample protection to the outer shell and effectively extending the lifespan of your travel mug.

The Sure–Grip Rubber Base on the ComfortSIP enables the travel mug to stick to surfaces and minimize the risk of spills. Additionally, the Sure-Grip Rubber Base diminishes noise when placing the mug on hard surfaces.

Ceramic Coating is preferred over metal for drinking due to its ability to preserve the beverage’s taste, better heat retention, aesthetic appeal, comfortable drinking experience, and dishwasher-safe convenience.

What is the best temperature for freshly brewed coffee?

All coffee is recommended to be brewed at an average temperature of 195 – 205 degrees Fahrenheit – but not every type of coffee should be consumed at the same temperature. 

There are four different coffee bean types (Arabica, Robusta, Liberica, and Excelsa) which are optimized by various drinking temperatures. The easiest way to discern the two is whether your preferred roast is light or dark. Light Roasts are recommended to be consumed at higher temperatures to bring out the most flavor and caffeine. Dark Roasts are recommended to be consumed at lower temperatures to avoid over bitterness and to improve smoothness. The safest range to consume coffee is between the Goldilock’s Range (130-150 F°) and the Heat Lover’s Range (150-170 F°). *See Graph Above for Temperature Zone References*

Enjoy your light roasts with ComfortSIP’s XL20 which settles temperatures to the Heat Lovers Zone (150-170 F°). Dark roasts should be consumed using ComfortSIP’s XL35 which drops temperatures to the Goldilocks Zone (130-150 F°). 

ComfortSIP XL35: Fantastic for dropping hot beverages like Hot Chocolate and Tea down to safe temperatures for children and toddlers! With a 360° lid and durable build materials, the ComfortSIP allows the best drinking experience for everyone in the family! 

ComfortSIP XL20: Some people like it just hot enough not to burn their mouth! The XL20 is for seasoned hot beverage drinkers who love to jumpstart their day with a heated, invigorating brew!

As your hot beverages come in contact with the ComfortSIP, excess heat is absorbed, quickly causing the temperature to cool.

Once cooled, ComfortSIP slowly releases the heat back into your beverage allowing the perfect temperature zone for upwards of 4 hours.

Vacuum insulation is a fantastic innovation in the drinkware space – but unfortunately, it takes a long time to be able to drink those hot beverages using a typical insulated travel mug. ComfortSIP’s Temperature Regulation couples the amazing properties of vacuum insulation with it’s proprietary heat sink feature allowing your hot beverages to quickly cool while holding that perfect temperature for a long time!

ComfortSIP isn’t just for hot beverages! Freeze the ComfortSIP to keep your drinks ice cold all day. Our proprietary temperature regulating technology acts as a built in icepack to protect your cold drinks for an extended period of time. No longer water down your cold brew with ice, the ComfortSIP is great for keeping your drinks chilled during long and hot days.

Want to enjoy hot coffee throughout the day? Pre-Charge the ComfortSIP to maintain a scalding hot beverage much longer than the typical vacuum insulated mug. Fill with boiling hot water, let sit for a few minutes, empty the hot water, and refill with your beverage of choice. Congratulations! Now you have a scalding hot beverage that maintains it’s burning hot temperature for multiple hours!

Why Create the ComfortSIP?

Current heat regulating travel mugs on the market often fail to maintain the ideal coffee temperature, either cooling it excessively or insufficiently.

Other heat regulating mugs on the market commonly suffer from issues like leaky lids and low-quality construction materials.

Unlike our competitors, ComfortSIP offers multiple temperature choices, recognizing that individual preferences for coffee temperature vary. Meaning: ONE TEMPERATURE DOES NOT WORK FOR EVERYONE!

It was our goal to create a temperature regulating travel mug that does not need to be electrically charged to drop and maintain temperature. Other temperature regulating travel mugs are only good for a couple of charges while ComfortSIP is able to be quickly used over and over again. 

Unfortunately, the current temperature regulating mugs on the market are inconvenient to travel with – that’s why we designed ComfortSIP to fit standard cupholders while sporting a Sure-Grip Rubber Base, Anti-Slip Silicone Sleeve, and 360° Lid, ensuring the upmost convenience while on the go.

Typically priced between $80 and $120, ComfortSIP provides an affordable option to temperature regulating mugs while using quality building materials and a long list of experience-optimizing features.

For the last 22 years, we have managed a product development firm whose team has experience in designing and manufacturing for some of the largest retailers in the world.

Finally, after years of developing and manufacturing market-ready products for others, we are launching our first product: ComfortSIP: The Heat Regulating Travel Mug

The Creation of ComfortSIP

Randy Williams, General Manager of Sino Sales & Support, (Product Development & Manufacturing Services) started on the ComfortSIP many years ago after over a decade of specializing in vacuum insulated products. As an avid traveler and coffee connoisseur, Williams has always looked for the best coffee flavor and new ways that can heighten that experience. After drinking coffee too quickly while using a vacuum insulated tumbler, Randy burnt his mouth and thought to himself, “We need a way to drop the temperature of scalding hot beverages fast, but still hold the heat people prefer?” Thus the ComfortSIP idea was born!

Over the many years of research and development, Williams experimented with hundreds of prototypes and various phase changing materials; visited multiple factories and tested a long list of aesthetic designs. Now, in 2023, Williams and the ComfortSIP Team are excited to launch on Kickstarter. We hope that each of our backers find the joy in using ComfortSIP like we do and hope your coffee drinking experience is now even better!
