    • Great purchase- recommend
Style: 40 Oz Color: Coconut
Great water bottle overall. It’s very durable and keeps ice water cold for a long time, even throughout the day. The design looks sleek and high quality, and the handle makes it easy and comfortable to carry around. It’s also easy to clean and doesn’t retain odors or tastes. Definitely a solid purchase and worth the price. ... show more

    • Perfect for gym
Style: 32 Oz Color: Black
This was the perfect size for water needed while doing a workout at the gym. It keeps water nice a cool. It fits into the center console cup holder if I remove my inserts- otherwise it’s too big. Love the handle on the top for easy carrying or clipping onto a backpack. Also enjoy the flip top with straw feature which makes it easy to drink from if doing cardio. Very sturdy and solidly built. I don’t see needing a replacement for some time. ... show more

    • Great Water bottle
Style: 64 Oz Color: Black
Love the water bottle! I decorated mine with stickers which definitely keeps me motivated to drink more water from it. It's very durable the straw is nice and it's easy to clean, and take apart/put back together. Water stays cold and it's easy to carry.

    • Cutest Hydroflask, Short Straw!
Style: 32 Oz Color: Coconut
My 2nd hydroflask, LOVE this one, color is so cute, quality is there. My one qualm is that the straw on this bottle is short, it doesn't go all the way to the bottom of the bottle. If you've never used hydroflask, the top of the bottle does have a small hole that will leak water when tipped, you get used to it! ... show more

    • Finally found my "Goldilocks" bottle!
Style: 24 Oz Color: Indigo
I've gone through a graveyard of cheap plastic bottles and leaky tumblers over the years, so I finally decided to bite the bullet and invest in a Hydro Flask. I picked up the 24 oz in Indigo Blue with the Wide Mouth Straw Lid, and honestly? I get the hype now. Here is the breakdown of my experience after using it daily for a few weeks: The Temperature (It's actually wild): The insulation is the real deal. I'm someone who needs my water ice cold. I filled this thing with ice and water at 8 AM before work, and by the time I was driving home at 6 PM, the ice was still clinking around inside. I haven't tested it with hot coffee because I don't like drinking hot stuff through a straw, but for cold water, it's a beast. The Straw Lid & The Seal: This was my biggest worry. I've had straw bottles before that leak if you so much as look at them the wrong way. The Seal: It is genuinely leakproof when closed. I can toss this in my passenger seat or into my gym bag, and as long as that nozzle is snapped shut, not a drop comes out. The seal around the threads is tight, too. Easy to Drink: The flow rate is perfect. You don't have to suck like you're trying to get a thick milkshake through a tiny straw, but it doesn't drown you either. It's silent, too—no weird squeaking or whistling noises when you sip. Build Quality & Color: The "Indigo Blue" is beautiful in person: deep, rich navy that looks professional but not boring. The powder-coat finish feels slightly textured, making it super easy to grip, even when your hands are sweaty from the gym. It feels solid, not tinny or fragile. Fit & Usability: The 24 oz size is the "Goldilocks" size for me. Fit: It fits perfectly in my car's cup holder (a huge win, since my 32 oz bottles never did). It also slides easily into the side pocket of my backpack. Easy to Use: The little flexible loop handle on the lid is surprisingly handy. I can hook it onto a carabiner or carry it with one finger while my hands are full of groceries. The Honest Truth (Cons) There are two minor things to know: Denting: It's stainless steel, so if you drop it on concrete, it will dent. I learned this the hard way with an older bottle. Treat it with a little care, or get a silicone boot for the bottom. Cleaning: The straw lid takes a little more effort to clean than a simple screw cap. You really need a little straw cleaner brush to get in there and keep it sanitary. Verdict If you are on the fence, get it. It's durable, it fits in your car, it doesn't leak, and having cold water available literally 24/7 has actually made me drink more water. Highly recommend. ... show more

    • Best drink bottle out there.
Style: 32 Oz Color: Black
Love this drink bottle. It keeps ice for a couple days. It doesn’t break when you drop it, but I would suggest buying the rubber bottom so your bottle doesn’t get dents in it. I love the straw top. When it’s shut it doesn’t leak. I will buy it over and over. I haven’t found another bottle that compares to it. ... show more
