Great Cup, Shame About The Markings & Size

Great cup, technically superior to the XCup. But …. . Why is it smaller than the XCup? Or why is there not a larger option available? The XCup has markings (1/4 cup, 1/2 cup etc) which I use for adding water to backpacking meals. This one however only has a “1 Cup” marking. For these reasons, this cup is gathering dust in my garage & XCup still gets regular outings

Pre-owned Odor

Cup seems to look and function "like new", but the inspection must not have included anyone smelling it. The odor of coffee is unfortunately not something that I enjoy.

Lightweight And Good For Hot Bevvies

Just as comfortable to hold as the old X-Mug Cool Grip with hot drinks. Super light and stows flat next to my cook pot lid.

Frontier Ultralight Collapsible Cup Perfect For Outdoor Reunions

I gave 'courtesy' collapsible cups (400 ml) to classmates planning a major college reunion next May, and they're thrilled with it. We hope to vastly reduce plastic waste by using this well-designed, convenient collapsible cup as auxiliary party-ware all weekend long!

Perfect For Light Weight And Compact Needs

Looking to add a cup to my lightweight kit and match well with my Jetboil. It is the perfect size for a good cup of coffee and when colapsed it packs well with the jetboil

Frontier Ultralight Collapsible Cup

I always carry it in my pocket so that I can drink water at any time. A very convenient mug. When my friends saw mine, they wanted the same one. You can quickly brew porridge or tea there, it folds up very simply and fits in any pocket

Super Durable And Easy To Store! 😀

I love this little cup!! 😍 It's cute and easy to store. It being collapsible is it's best feature. I can take it anywhere, such as to work or pack it to go camping or on a trip. When I take it to work, I just collapse it and slip it into a small compartment in my purse. It's lightweight and durable too! It's even dishwasher safe! It's also super easy for my small kids to drink from and I don't ever have to worry about it being broken. It's very hard to damage. I want more of these in all sizes and I will be purchasing some in the near future! 10/10 would recommend.
