Learn how to use the Kelso Tumbler 15 oz 2-Pack for your morning coffee routine, with tips on preparation, safety, and cleaning.
Quick answer
Use the Kelso Tumbler 15 oz 2-Pack for morning coffee by pre-warming it, filling safely, and cleaning properly to enjoy a spill-free commute.
Why the Kelso Tumbler works for coffee
The Kelso Tumbler's silicone sipper spout with built-in valve stops liquid flow when not in use, making it ideal for car or desk. Its 15 oz size suits a standard coffee serving, and the 2-pack gives you a backup or a second drink.
Note: This tumbler is not insulated, so your coffee will cool faster than in an insulated cup. Plan to drink within about 30-45 minutes for best warmth.
Steps for a great morning coffee with the Kelso Tumbler
- Pre-warm the tumbler: Fill the tumbler with hot tap water for 2 minutes before adding coffee. This reduces heat loss from the cold plastic.
- Fill with coffee and secure the lid: Pour your coffee, leaving about 1 inch of headspace to avoid pressure buildup. Screw the lid on tightly and push the spout closed. Check that the spout valve is fully closed before moving the tumbler.
- Drink within 30-45 minutes for best temperature: Because the Kelso Tumbler is not insulated, coffee cools quickly. Sip within this window for a satisfying warm drink. If you need longer heat retention, consider a different tumbler design.
- Clean immediately after use: Rinse with warm water and mild soap. Use a bottle brush to clean the spout valve area to prevent residue buildup. Avoid soaking the lid in hot water for extended periods to protect the silicone seal.
Product facts
- Kelso Tumbler, 15 oz. (2 Pack): The silicone sipper spout has a built-in valve that stops water from flowing when no one is drinking. This prevents coffee spills in the car or on your desk, even if the tumbler tips over.
