START LAB insulated tumbler with straw, 1100 ml (37.2 oz)A full day of water in one cup that still drops into your car's cup holder.
The START LAB insulated tumbler with straw holds 1100 ml (37.2 oz), enough for a long workday or a drive without a refill stop. The liner your drink touches is 316 stainless steel, set inside an insulated, leak-proof body built for the car, the gym bag and the desk. Its 75 mm (2.95 inches) bottom suits the majority of car drink holders, which matters on a cup this size.
- 1100 ml (37.2 oz) in one fill
- 316 stainless steel liner
- Leak-proof build
- Base made for car cup holders
Three figures worth knowing
One large cup or a string of refills
A small everyday cup
- Runs dry before the morning is over
- Sends you looking for a sink or a cooler
- Rolls around the seat when the holder is too wide
The large START LAB
- Starts the day with a full load of water
- Straw lets you sip at your desk without opening a lid
- Narrow base drops into most car cup holders
Hold a ruler over your cup holder
The base measures 75 mm (2.95 inches) across. Most car holders take that, but some older consoles and narrow door pockets run tighter. Check the opening before you order. If yours is that wide or wider, the tumbler sits down in it properly.
Who this cup suits
A good pick if you
- Drink water all day and dislike frequent refills
- Want one cup that lives in the car and moves to your desk
- Prefer a straw at the gym or while you work
Look elsewhere if you
- Want a compact cup for one drink; the smaller CHaKOLAB straw cup suits that better
- Need something that slides into a backpack side pocket; the START LAB insulated water bottle is shaped for that
The details
Straight answers
How many ounces does this tumbler hold?
It holds 1100 ml, which is about 37.2 oz. That is a little over a quart, so a single fill covers most of a working day.
Does the START LAB tumbler fit a car cup holder?
In most cars, yes. The base is 75 mm (2.95 inches) across and is made for standard car cup holders. Narrow or shallow holders may not take it, so measure yours first.
Is an insulated tumbler with straw good for hot coffee?
Not really. The cup is insulated, but a straw pulls hot liquid into your mouth fast, which is easy to regret. Fill it with water, iced coffee or cold drinks, and keep hot coffee for a mug you sip from.
How is it different from the ceramic-lined version?
The liner. This one is lined with 316 stainless steel. The Chako Lab ceramic lined tumbler has a ceramic liner and a handle, if you prefer ceramic against your drink.
Can it go in the dishwasher?
Dishwasher safety is not mentioned in the listing, so clean it by hand using mild soap and warm water, and pass a straw brush through the straw.
