Shaker bottles, packs of bottled water and hydration packs are left out. - **Match the size to the session.** Water Bottle Advisor says bottles under 32 oz are too small for a full workout, calls 32 to 40 oz the sweet spot and suggests 64 oz for long sessions. Bon Appétit says there is no single right size and a 40 oz bottle may be worth the bulk if you want to drink more. The [Iron Flask 40 oz](https://twelvetabs.com/reviews/best-water-bottles-for-the-gym/#pick-1) is 40 oz, the [Coolflask Half Gallon](https://twelvetabs.com/reviews/best-water-bottles-for-the-gym/#pick-5) is 64 oz and the [YETI Rambler](https://twelvetabs.com/reviews/best-water-bottles-for-the-gym/#pick-2) is 26 oz. - **Pick the lid for how you drink.** Bon Appétit says straw lids suit hands-free sipping, spout and chug lids suit bigger gulps, and screw tops are simple but need two hands. It adds that straw lids take extra cleaning. The [Iron Flask 40 oz](https://twelvetabs.com/reviews/best-water-bottles-for-the-gym/#pick-1), the [Coolflask Half Gallon](https://twelvetabs.com/reviews/best-water-bottles-for-the-gym/#pick-5) and the [Stanley Quencher](https://twelvetabs.com/reviews/best-water-bottles-for-the-gym/#pick-7) have straws, the [YETI Rambler](https://twelvetabs.com/reviews/best-water-bottles-for-the-gym/#pick-2) has a chug cap and the [Takeya Actives](https://twelvetabs.com/reviews/best-water-bottles-for-the-gym/#pick-3) has a spout lid. - **Treat leakproof as a claim to check.** Water Bottle Advisor says to confirm the bottle is labeled leakproof, since splashproof or spillproof is not enough, and notes that locking lids add protection in a gym bag. Amazon's summary rates leak-proof as positive only for the [Takeya Actives](https://twelvetabs.com/reviews/best-water-bottles-for-the-gym/#pick-3), mixed for five picks and negative for the [Stanley Quencher](https://twelvetabs.com/reviews/best-water-bottles-for-the-gym/#pick-7). - **Know what insulation costs.** Bon Appétit says double-wall insulated stainless steel keeps ice water cold for hours but is heavier than plastic. Water Bottle Advisor calls 18/8 stainless steel the best choice and says plastic is cheaper but can sweat. The [Sahara Sailor](https://twelvetabs.com/reviews/best-water-bottles-for-the-gym/#pick-6) is the plastic pick. - **Check the base for cup holders.** Water Bottle Advisor says a base under 3 inches wide fits most cup holders.

The other 96 were organic listings, many of them shaker bottles, packs of bottled water, jugs sold in several sizes and the same bottle shown in several colors. We narrowed the rest to 10 contenders, read each product's own Amazon page and kept seven. Three were left out: - **CamelBak Podium Chill.** Its listing describes a bike bottle, and Amazon's summary calls temperature retention, insulation and sealing mixed. - **Under Armour Insulated Half Gallon.** Amazon's summary rates lid functionality negative and calls leakage, durability and value mixed. - **AQUAFIT 1 Gallon.** Amazon's summary rates durability negative, and two critical reviews report a crack and a burst. We also skipped the Owala FreeSip, which shows one rating count of 141,427 on eight cards, and the Stanley IceFlow and HydroJug bottles, which share counts across sizes and colors. Pooled counts can hide which size the ratings cover. Hydro Flask has its own guide. No Wirecutter page appeared in Google's top 20 for this phrase, so there is no Wirecutter pick in the comparison table. ## Questions people ask ### What size water bottle is best for the gym? Water Bottle Advisor says bottles under 32 oz are too small for a full workout and calls 32 to 40 oz the sweet spot. It suggests 64 oz for long sessions.
