The Milton Duo DLX 1000 is the best overall Milton bottle here: vacuum insulated, a 24 hour claim, a cup lid and a one year warranty. Milton sells steel bottles in two families, plain steel bottles and Thermosteel bottles with vacuum insulation. This list covers five. The Aqua 1000 and the Comet 1000 are plain steel, and Milton states the Comet as single wall. The Duo DLX 1000 and the Flip Lid 1000 are vacuum insulated. Milton gives both a 24 hour claim. The Copper Aqua 1000 is made of copper.
The names say 1000, but the real capacities vary. Milton lists the Aqua below a litre. The Comet variant falls short of a litre as well. Choose between plain and insulated first. Then pick the lid, a screw cap, a flip top or a cup lid.
The Milton Duo DLX 1000 Thermosteel Hot and Cold Water Bottle is the cup-lid model. It holds 1000 ml. Milton sells other sizes too. The body is 304 grade stainless steel, vacuum insulated with an inner and an outer layer. Milton says drinks stay hot or cold for 24 hours.
A screw cap closes the bottle. A flip lid on top doubles as a cup. Milton calls the design leak proof and gives a one year warranty.

Pick the body type first. The Aqua and the Comet are plain steel, and Milton claims no hours for either. The Duo DLX and the Flip Lid are vacuum insulated and carry a 24 hour claim. The Copper Aqua is copper.
Next, read the real capacity. The Aqua is the smallest at 920 ml. The Comet variant is next. The others are 1000 ml. Milton also sells most of these in other sizes, so a smaller or larger one may exist.
Look at the lid. A screw cap is plain. A flip top cap opens without unscrewing. The Duo DLX flip lid doubles as a cup. The Comet has a flip-top cap with a lid. Milton claims a leak-proof build for four of the five. The Copper Aqua listing does not.
Check care too. The cup lid on the Duo DLX is a second part to keep clean. The Aqua is hand wash only. Milton says its bottles can be cleaned with a mild detergent or dish wash liquid. The others come with no care steps.
Look at warranty next. The Duo DLX and the Flip Lid list one year. The others list none.
The Duo DLX 1000 is the best overall on the listed specs: a 24 hour claim, a one year warranty and a lid that works as a cup. The Flip Lid 1000 has the same claim and warranty, with a copper coated wall and a flip top cap instead.
For plain water, the Aqua 1000 has the most complete size and weight figures. It weighs 280 g. The Comet suits a buyer who wants a flip lid without insulation. The Copper Aqua is the choice for copper.
