The Nalgene 24 oz On The Fly Lock-Top Water Bottle is built for easy sipping and care-free storage. The fortified locking chug cap pops open with one hand and locks shut just as easily, so you can sip at a red light, on the treadmill, or during your commute without breaking stride. At 3 inches wide, its slim profile slides into work bags, gym bags, backpacks, and car cup holders with ease, making it just as at home on your desk as it is on the trail or at the gym. The impact-resistant body is practically indestructible, surviving drops on gym floors, office stairwells, and hiking trails, while the airtight seal means you won’t have to worry about it leaking in your bag. Measurement markings make it easy to track your daily intake or mix in electrolyte powders, and the whole thing goes straight in the dishwasher when you’re done. Please note: the measurement lines stop at 20 oz, but the bottle holds 24 oz. Pop it, lock it, and go.

Customers love this water bottle’s size and portability, finding it perfect for travel and easy to carry with one hand. The bottle is leak-proof with zero spills, and customers appreciate its ease of cleaning and compatibility with cup holders. The durability and lid closure receive mixed reviews – while some say it lasts 15+ years, others report it cracking within four months, and while the locking mechanism helps keep it closed, the lid tends to pop open.
