Outdoor drinkware
The Blue Sky Gear Double Up Cup is a 10 fl oz vessel built for outdoor meals. It pairs a hard anodized aluminum shell with a BPA-free, food-grade silicone liner that handles both hot and cold drinks. The two parts nest together for hot beverages or separate for cold ones. Both components are dishwasher safe.
Campers and minimalists
Backpackers who want one cup for coffee and water will like the dual-use design. The 300F rating covers boiling liquids without extra gear. Buyers who want more storage or a sealed travel mug should look elsewhere. The open top offers no spill protection.
Pack and kitchen
The aluminum shell and silicone liner pack flat and add almost no bulk to a cook kit. They free up space by replacing separate hot and cold cups. No stove, fuel or special cleaner is required. The parts wash in any dishwasher after the trip.

Questions about this item
Do I need a separate heat source to use the hard anodized aluminum outer cup with hot beverages?
No, the outer cup is designed to hold hot liquids directly and withstands temperatures up to 300F.
Can I keep using my existing 10 fl oz lids with the silicone lining on its own?
The silicone lining is a flexible sleeve without a rigid rim, so standard snap-on lids for a 10 fl oz cup will not seal against it.
How can I confirm the double-wall insulation is performing after the first wash?
Pour hot water into the assembled cup; the outer aluminum should stay cool to the touch while the lining holds the heat.
