Whether you’re joining a Pilates class, planning on upping your treadmill time, or hitting the squat rack to make some gains, a water bottle is a must-have in your gym bag. Not only do they keep your liquids cold, but they serve as gentle reminders to hydrate throughout your workout. If you’ve been reusing or cycling through your plastic Dasani bottle, it’s time to level up, and no, I’m not talking about trading your old plastic bottle for a new one. I’m suggesting a real upgrade.

Not only are single-use plastics bad for the environment, but some contain bisphenol-A, aka BPA for short—a hormone disruptor—that could impact your blood pressure, glucose levels, and heart health. If you’ve been needing a push, this is your sign to invest in water bottles for the gym.

With so many options, it can be hard to narrow it down (and no, not all water bottles were created equal), so we’ve combed through the digital aisles in search of the best water bottles for keeping hydrated, specifically at the gym. Among our search, we found no shortage of options, ranging from space-saving, collapsible bottles to one-galloners with motivational messaging for those in need of a friendly sipping reminder.

Below, you’ll find the best, no-frills water bottles of every budget, style, and size. Happy sipping!

The best water bottles for the gym

Best Overall

Hydro Flask, 24-Ounce Standard Mouth with Flex Straw Cap — $45.00

Whenever you’re headed to the gym for your next training session, don’t forget the internet-raved Hydro Flask. While simple on the outside, the bottle has some stand-out features that make it the best overall choice. Double layered in stainless steel, the bottle keeps liquids cold for up to 24 hours (even hot liquids for up to 12 hours) and has a condensation-free exterior (goodbye, water drips). The honeycomb-like cap seals in liquids, preventing water leaks, and has a built-in straw and handle for travel and easy sipping access. Even more to love? It comes in ten fun colors, including starfish yellow, kiwi-like green, and laguna blue.

Best Shaker

Blender Bottle, Classic Shaker Bottle — $10.00

Once you get your hands on a Blender bottle, you’re not going to want to stop shaking it (Alexa, play “Hey Ya” by Outcast). Beyond holding 20 ounces of liquid, it comes with a stainless steel, wire ball that whisks up and takes the lumps out of all of your protein or pre-workout concoctions. The wide mouth makes it easy breezy to add a scoop of your favorite protein powder, and the cap seals in liquids. Leaks be gone!

Best Straw

Owala, Freesip Insulated Stainless Steel Water Bottle — $30.00

Of all the water bottles with straws, Owala’s Freesip reigns supreme. Featuring a built-in straw, the Freesip allows you to drink water without tilting the bottle back (ideal for running) or use the sprout opening for a larger gulp. Conveniently, it comes with a push-open button, making sipping easy with just a push, and a carrying loop for convenient transport to your next yoga, Pilates, or HIIT session. We love that the bottles keep liquids colds for up to 24 hours, so you don’t have to worry about drinking luke warm water (yuck, but no shade if you like that temp).

Best Collapsible

Stojo, 20-Ounce Bottle — $20.00

Some water bottles can be clunky to carry, but not this one from Stojo. This 20-ounce bottle collapses into a sphere, saving gym bag space and is lighter to carry. It’s made of LFGB-approved silicone, which means it’s made of a silicone that’s undergone more rigorous testing, and is free of icky, not-so-good for you chemicals like BPA, lead, and phthalates. Plus, it fits easily into a step mill or treadmill cup holder. Whenever you’re ready to sip, just pull the cap up and fill with your beverage of choice.

Best Filter

Larq, Filtered Bottle — $50.00

The Brita of water bottles, Larq’s water bottles have a built-in straw that uses Nano Zero technology to filter out lead, heavy metals, chlorine, and microplastics for a smooth and refreshing sip. Impressive, if you ask me. The bottle itself is double-insulated with stainless steel to keep your water cold for up to 24 hours and comes with a silicone-coated carabiner, so you can hook it on your bag or backpack whenever you’re on the go.  The filters last two months, sieving a whopping 40 gallons of water and saving hundreds of water bottles from touching landfills—it’s a win-win for you and the environment.

Best Glass

W&P, Portable Water Bottle — $30.00

W&P seriously has some of the prettiest bottles we’ve ever seen, and this one feels luxe. Constructed out of lightweight but durable glass, the bottle is sleek and never retains any funky odors. Plus, it comes with a silicone wrap that does triple duty as a bottle protector, slip-resistant holder, and handhold. It fits easily into the side of your bag or in a cup holder. Yippee for no slips and slides.

Best Design

S'well, Geode Rose Bottle — $35.00

Anything from S’well is like a piece of art, and this Geode Rose bottle is beautiful as it is functional. Inspired by a rose quartz stone, the bottle has pink, blue, and yellow hues that make this bottle stand out from its counterparts, and is insulated with stainless steel to keep drinks cold all day long. Each bottle fits into a gym bag, is easy to carry, and fits easily into a cup holder.

Colors available: Geode rose

Best Motivation

Fidus, Large 1-Gallon Water Bottle — $28.00

Hydration starts way before your workout, and this bottle from Fidus keeps you on track all day long. The one gallon bottle features inspirational quotes and time markers to remind you of your daily water intake, a built-in straw for easy sipping, and skid-free grip to prevent slips and slides on gym surfaces.

Best Lightweight

Nalgene, 32-Ounce Narrow Mouth Sustain Water Bottle — $16.00

Made of 50 percent recycled and BPA/BPS-free plastic, Nalgene’s 32-ounce bottle is one of the lighter bottles on the list. It clocks in at only 6.25 ounces, making it easy to throw in your gym bag or carry with a strap. What’s more, it comes with a narrow nozzle, which prevents liquid from splashing back out during a run.
