Why the Right Lid Matters
A bottle is only as useful as the lid you screw onto it. The same 17oz body can be a commuting companion, a gym bottle, or a bedside water source — the cap decides which. S'well caps and lids are built to swap, so you can change how you drink without buying a whole new bottle.
The Traveler Flip Straw Lid is the classic one-handed option: flip, sip, snap shut. If you prefer a faster flow during workouts, the Explorer Flip Straw Lid pairs a wider straw opening with a sturdy handle. Both are designed to seal cleanly, so they can ride in a bag without leaking.
Straws Explained: Glass Straw Set vs. Bottles With Built-In Straws
There are two ways to get a straw experience. The first is a reusable straw you add yourself — a glass straw set gives you a smooth, taste-neutral sip and works with tumblers, carafes and any wide-mouth vessel. The second is a bottle that arrives straw-ready, like the Tumbler with Straw | 24oz or the Explorer with Flip Straw Lid | 18oz.
Which should you choose? If you already own a bottle you love, a separate straw is the cheaper upgrade. If you are starting fresh, a built-in flip straw means one less loose part to lose. Either way, look for caps that are dishwasher-safe and easy to disassemble — that is where most lids fail over time.
Matching Caps and Lids to Original, Traveler and Explorer Bottles
S'well bottles come in families, and each family has its own thread and opening size. Getting the match right is the whole game.
- Original Bottle: The slim, tapered shape. The Original Bottle | 17oz and Original Bottle | 25oz take standard screw caps and are the easiest to pair with a glass straw.
- Traveler: A wider mouth built for ice and thicker drinks. The Traveler | 16oz accepts the Traveler Flip Straw Lid, and the 16oz Traveler Flip Straw comes pre-fitted if you would rather not swap anything.
- Explorer: The largest family, from 18oz up to 32oz. The Explorer | 32oz is the hydration workhorse, while the Explorer with Flip Straw Lid | 24oz and Explorer with Flip Straw Lid | 32oz ship ready to sip.
Before buying any cap, check the bottle name and size. A lid made for a Traveler will not thread onto an Explorer, and a straw cut for a 32oz bottle will sit too tall in an 18oz one.
Food, Lunch and Travel Containers
Hydration is only half of a packed bag. S'well's food side covers breakfast, lunch and leftovers with the same insulated approach.
The S'well Eats™ | 21.5oz is the all-in-one option: a stainless base plus a nesting bowl that doubles as a serving dish. For salads, the Salad Bowl Kit | 64oz keeps dressing separate until you are ready to toss, and the Salad Bowl Kit XL | 184oz handles family-size portions or meal prep for the week.
Smaller items matter too. A Bento Box keeps components apart, the Food Canister Set stores dry goods or soup, and the Lunch Tote carries the whole kit. If you are packing for two, a Glass Prep Bowl Set | 12oz or Prep Bowl Set | 10oz rounds out the set.
Bundles and Sets: Smart Ways to Start
If you are outfitting a kitchen, a car and a desk at once, bundles save you from guessing at compatibility. A curated set like the Cobalt Glow Essentials Bundle groups matching pieces so the colors and sizes already work together.
For travel, the Travel Bottle Set is built for packing light, and the Droplet Tote keeps bottles upright in transit. Entertaining? A Wine Chiller, Ice Bucket XL and a set of Wine Tumbler | 14oz glasses turn a backyard table into something a little more considered.
Start with the bottle you reach for most, then add the cap, straw or container that removes your biggest daily friction. That is how a bottle collection becomes a system.
