ddLUCK Silicone Foldable Cup (2 Pack) BPA Free Collapsible Travel Mugs with Sealing Lid
Product description
The essentials
A collapsible travel mug is one of those bits of kit you don’t realise you need until you’re trying to squeeze a takeaway cup, a water bottle and a spare layer into the same bag. The ddLUCK Silicone Foldable Cup set (2 pack) is aimed at exactly that: a reusable, fold-flat cup you can carry easily for picnics, camping, road trips and outdoor hiking.
On paper, it’s a straightforward concept done in a practical way. The body is silicone, there’s a stainless steel rim to make drinking more comfortable, and you get a plastic sealing lid designed to keep dust and dirt out. It also folds down to a very small footprint, which is the main reason people go for collapsible cups over bulkier travel mugs.
What you’ll notice day to day
The foldable design is the headline feature. According to the product details, after folding the height is only 1.5cm / 0.59”. That’s the sort of size where it’s much easier to stash in a pocket, purse, backpack or suitcase without it becoming a “thing” you have to plan around.
In use, the stainless steel rim matters more than you’d expect. It gives you something firmer to hold and drink from, rather than a fully soft silicone edge. There’s also a tick mark inside the cup described as easy to read, which can be handy when you’re portioning water for a walk or trying to keep a rough amount.
One practical plus: the product mentions it can be hung on the bag using a strap and portable hook. If you’re the type who likes gear that doesn’t constantly end up at the bottom of your rucksack, that’s a nice touch.

Where it shines (and where it may fall short)
This is best seen as a portable, space-saving cup for everyday outdoor life. If you often carry food and drink on the move, a collapsible cup set like this can make sense because it’s reusable, it’s described as easy to clean and non-staining, and it’s built around keeping stuff out with the sealing lid.
That said, it may not suit everyone. A collapsible cup is inherently a bit more “simple” than a fully insulated travel mug that’s designed to keep drinks hot or cold for long periods. If your priority is temperature retention for commuting or all-day walks, you may feel this set comes down more towards convenience and packability than thermos-level performance.
Also, it’s only 260ml per cup, so if you regularly want a larger single drink volume, you might find yourself refilling more often.
How to get the most from it
A good way to think about it is: use it when you want a drink that’s easy to carry, easy to rinse, and not bulky. For example, on a day out you can fill one cup at a café before heading to the park, take the second for later, and then fold them up once you’re back. The lid is described as preventing dust and dirt getting in, which is useful when the cups are rolling around in a bag.
If you’re hiking, the stainless rim gives a more stable drinking experience than an all-silicone rim, but you still get the benefit of folding flat afterwards.
Should you buy it?
A solid pick if you want a reusable collapsible travel mug for outdoor days where storage space matters, and you’ll appreciate a sealing lid and a stainless steel rim for easier drinking. The 2 pack also means you can keep one ready while the other gets washed and dries.
You may want to skip it if temperature retention is your main goal, or if you’d rather carry one larger mug than refilling 260ml cups during longer trips.
Worth considering if you’re planning picnics, camping or hiking and you’re trying to keep your kit lean. It might not be a great match if your routine is very “commute-focused” and you need a cup that behaves like a fully insulated hot drink system.
