This is my third S'well bottle and it's just as good as the first. The 25 oz size is perfect for my gym sessions – it holds enough water to last through a workout without being too bulky. The Onyx color is sleek and goes with everything. I love that it doesn't sweat, so my desk stays dry. And the fact that it keeps drinks cold for over a day is incredible – I've had ice in there for 24 hours and it's still cold. Highly recommend!
I like this bottle, but it's a bit heavy when full, especially if you're carrying it by the small loop. The insulation is fantastic – I filled it with iced water at 7 AM and it was still chilly at 9 PM. The Onyx finish looks sharp, but it does show fingerprints. Still, a quality bottle overall.
I keep this bottle on my desk at work. It's the perfect size – not too big, not too small. The black color is professional, and it fits in my bag's side pocket. I often forget to finish my water, but it stays cold all day, so I always have refreshing water. The wide mouth makes it easy to add ice and clean. Great investment.
I bought this because of the hype, but I'm not thrilled. The bottle is well-made, but it's not as magical as everyone says. It does keep water cold, but after 12 hours it's just cool, not icy. Also, it's quite heavy and uncomfortable to hold for a long time. The cap is a bit hard to twist at first. It's okay, but I think there are better options for the money.
My husband is a construction worker and he needed a bottle that could handle the heat and keep water cold. This S'well does exactly that. He says even in 100-degree weather, his water stays cold for hours. The Onyx color hides dust and dirt, which is a plus for his job. The size is perfect for his tool bag. We're buying another one for our son.
I love the sleek design and the insulation is top-notch. But I wish it had a handle or a loop to carry it easily – the cap is smooth and slippery. I've almost dropped it a few times. Otherwise, it's a great bottle for everyday use.
I've tried so many water bottles, and this one is the best. It looks elegant, keeps water cold for a ridiculously long time, and the Onyx finish doesn't show scratches easily. I've had it for a year and it still looks new. It's a bit pricey, but it's worth it because I use it every single day. I even bought one for my sister.
This is a great bottle – maybe a tiny bit heavy, but the cold retention is amazing. I filled it with ice and water on a road trip, and 18 hours later there was still ice. The Onyx color is sleek, but it shows dust and lint easily, so I have to wipe it often. Overall, I'm happy with it.
I bought this to replace a cheap plastic bottle, and what a difference! The S'well feels premium and keeps my pre-workout drink ice cold from morning to afternoon. The 25 oz is perfect – not too big to hold during a workout. No condensation means no slippery bottle, which is a bonus. Definitely recommend.
