10 Best Collapsible Cups

This collapsible silicone cup is a practical choice for camping, hiking, and travel thanks to its compact size and lightweight design. It holds 180 ml (about 6 ounces), which is enough for a small drink like coffee or water but might be a bit small if you prefer larger servings. The food-grade silicone is BPA-free, odorless, and heat-resistant, so it can handle hot and cold drinks safely.

When folded, it becomes very thin—only about half an inch tall—making it easy to stash in a backpack or purse. The included lid fits tightly to keep dust out, though it’s not explicitly described as leak-proof for carrying liquids upside down. Cleaning is simple as the cup is dishwasher safe and has a smooth interior that resists stains. The set comes with four cups in blue and orange, each with a spiral texture that helps grip, plus carabiners for easy attachment.

While it suits casual outdoor use and travel, the relatively small capacity and the absence of a strong leak-proof guarantee might make it less suitable if you want a larger or fully spill-proof cup. It remains durable, reusable, and convenient—especially for those who value easy storage and portability.

This IYYI collapsible cup is a handy choice for anyone who loves camping, hiking, or traveling light. Its standout feature is how thin it becomes when folded—just about half an inch—making it easy to carry in a pocket or backpack. The cup is made from food-grade silicone with a metal rim that helps it hold its shape and feels sturdy when you drink from it.

It comes with a lid that fits tightly, helping keep dust and dirt out, which is great for outdoor use. Cleaning is simple since the cup is dishwasher safe and its smooth silicone surface prevents stains and odors. However, the cup’s capacity is about 6.15 fluid ounces, which might be on the small side if you want a larger drink. Also, while the lid is good for keeping things clean, it doesn’t claim to be fully leak-proof, so it might not be ideal for carrying liquids in a bag.

This collapsible cup strikes a good balance between portability and durability, making it a solid pick for light, on-the-go drinking needs.

The Tessco collapsible shot glasses come in a set of six, each holding about 2.5 ounces (75 ml), which is a modest size ideal for quick drinks like water, juice, or small servings of wine. Made from stainless steel, these cups are sturdy and rust-resistant, meaning they should last well through outdoor adventures without breaking or fading. Their foldable design is a big plus for saving space—when collapsed, they become compact enough to clip onto your backpack or belt with the included keychain, making them very portable.

Each cup also comes with a lid, which adds convenience for carrying liquids without spilling, though it cannot be guaranteed that the lids are fully leak-proof. The metal construction might be less comfortable for hot drinks compared to silicone alternatives, but stainless steel is easy to clean and does not hold odors or stains. Weighing just over 70 grams each, these cups are lightweight for travel.

These cups are great for camping, hiking, or cycling where you need something durable and compact, but their small 2.5 oz capacity is not suited for larger drinks. While cleaning may require attention due to the metal and folding parts, maintenance is straightforward. They are ideal for outdoor enthusiasts who want a reusable, space-saving drinking solution for short, casual use rather than regular large servings.
