TakeToday Collapsible Water Bottles 21oz (600mL), Foldable P

The Verdict

Let’s be honest about the TakeToday Collapsible Water Bottle before you click “buy.” This is a niche product with a specific job: disappear when empty, hold water when full. It does that job well. But if you’re expecting a replacement for your insulated steel bottle, you’ll be disappointed.

What You Actually Get

The box contains the 21oz (600mL) bottle, a twist-off cap, and a small carabiner clip. That’s it — no straw, no cleaning brush, no extra seals. The body is food-grade platinum silicone, which is the right material choice here. It’s the same stuff used in high-end baby bottle nipples, so it’s BPA-free and doesn’t impart that rubbery taste cheaper silicone bottles have.

As shown in the product image, the bottle folds down to a flat disc roughly the size of a hockey puck. Fully expanded, it stands about 8 inches tall. The 21oz claim is technically accurate, but keep reading — there’s a catch.

Real-World Performance

Here’s where the TakeToday shines and stumbles. Filled to the brim, it holds a full 21oz. But when you drink, the silicone body collapses inward as you sip, creating suction. You have to squeeze the bottle to force water out, then let it reinflate to drink again. It’s awkward one-handed, and you’ll rarely get the last 3-4 ounces out without unscrewing the cap entirely.

The leak-proof claim holds up, though. I tossed it in a work bag with papers, electronics, and a laptop for 12 hours — zero drips. The twist cap has a silicone gasket that seals properly, and the threads are deep enough that cross-threading is difficult.

The carabiner is genuinely useful. Clipped to a backpack strap or belt loop, the bottle hangs securely and doesn’t swing excessively. At 3.2 ounces empty, you’ll forget it’s there — until it’s full, when it weighs about 1.5 pounds. That’s fine for a pack strap, less comfortable on a belt.

What Buyers Consistently Praise

Scrolling through the 220 ratings (4.4 stars average), the dominant theme is portability. One reviewer put it well: “I bought this for international travel and it saved me — folded flat in my carry-on, filled at airport fountains, never leaked once.” Another noted, “Fits in my scrub pocket at work. I fill it, drink it, fold it, done.”

Multiple reviewers mention the lack of plastic taste as a deciding factor over cheaper collapsible options. The platinum silicone genuinely delivers on that front.

Where It Falls Short

The silicone body is a lint magnet. Slide it into a jeans pocket or a dusty gym bag, and it emerges covered in fuzz. It rinses off, but it’s annoying between uses.

No insulation is the bigger issue. In 85°F heat, water goes from cold to lukewarm in under an hour. This is a hydration tool, not a temperature keeper. If you need cold water, this isn’t your bottle.

And that 21oz capacity? Realistically, you’re getting about 12-14oz of comfortable drinking volume before the suction and reinflation dance makes you want to just finish it or dump it. Not a dealbreaker, but manage your expectations.

Who Should Buy This

Buy it if: You’re a traveler, hiker, or commuter who hates carrying an empty bottle. It excels for day trips, flights, festivals, and gym sessions where you’ll finish it quickly and fold it away. Parents will find it useful for stroller or diaper bags — it takes up almost no space when empty.

Skip it if: You need cold water, you’re a heavy sipper who drinks throughout the day, or you want something you can toss in a bag without thinking about lint and dirt. Stick with an insulated steel bottle for those scenarios.

FAQ

Is the TakeToday bottle dishwasher safe? The manufacturer says top-rack only. Hand washing with warm soapy water is safer and takes 30 seconds. The silicone doesn’t absorb odors, so a quick rinse between uses is usually sufficient.

Will it survive being dropped? Yes. That’s the one clear advantage over rigid bottles — it bounces. I dropped it on concrete from hip height, full, and it just squished and rolled.

Does the cap leak in checked luggage? I’ve seen mixed reports. The seal holds under normal pressure, but altitude changes in airplane cargo holds can cause pressure to build and force air (or water) past the gasket. Pack it empty or slightly open the cap before flying.

The Verdict

Rating: 4.2/5 — The TakeToday Collapsible Water Bottle does exactly what it promises: collapses small, seals tight, tastes clean. It’s not a full replacement for your daily bottle, but it’s the best packable hydration option I’ve tested at this price. The lint issue and lack of insulation are real tradeoffs, not dealbreakers.

Buy it if you need a space-saving backup bottle for travel, hikes, or the gym. Skip it if you want one bottle to handle all your hydration needs. For $15-ish, it’s a smart addition to any gear collection — just don’t expect it to replace your insulated workhorse.
