Owala FreeSip Insulated Stainless Steel 24 oz

Averaged from 2 published ratings + 2 derived from review text
The verdict

Owala's FreeSip Water Bottle lets you sip through a straw or swig from the spout without unscrewing anything. Pack Hacker and Serious Eats both reviewed it and praised the durability, the cold retention, and the convenient design. The body is stainless steel with a soft plastic cap layer; it cleans easily, though reviewers noted the plastic part can show blemishes over time. It suits anyone who wants a leakproof insulated bottle that drinks two ways.

Full review

One lid that sips and swigs

The FreeSip lid is the whole pitch: a narrow straw spout for sipping and a wider opening for a proper swig, with no cap to unscrew or swap. Good Housekeeping's Nicole Papantoniou found the straw side took barely any effort, needing only light pressure around the spout to pull a full drink. The wide opening doubles as the vent, which is what makes the swig work and also what creates a potential leak path. Opening it means flipping the handle and pressing a button, an extra beat that some people never stop noticing.

Cold holds well, hot is off the table

Good Housekeeping's lab found the water inside rose only 13 degrees Fahrenheit over a day, where weaker bottles rose more than 20. Serious Eats' Grace Kelly, who has carried one for years, called it sturdy and smooth to sip from but ruled out hot drinks, since the straw is not built for them. The mouth is wide enough for ice cubes and the base is round enough for a cup holder, though the 24-ounce size is modest if you want to fill once and forget about it.

It dents, and the sub-cap fights you

Durability is where the enthusiasm stops. Good Housekeeping's testing dented the bottle, and Pack Hacker recorded a blemish forming just above the debossed logo with normal use, noting the soft plastic is prone to it. Pack Hacker also found that separating the two lid pieces takes more force than feels right, and that gunk collects in the gap between them. The silicone seal has to come out for a proper clean and go back in correctly, or the bottle leaks.

Cheaper than Hydro Flask, less rugged than YETI

At around $30 the 24-ounce FreeSip undercuts the $40 to $50 that comparable Hydro Flask and YETI bottles command, and CleverHiker rated it 4.2 out of 5. What you give up is toughness and low-maintenance cleaning. The 32-ounce and 40-ounce versions add capacity but lose cup-holder compatibility, so the 24-ounce is the one that fits the way most people actually carry a bottle.

Strengths

  • +Provides both sip and swig drinking options without unscrewing or switching caps
  • +Keeps drinks cold for up to 24 hours with ice cubes
  • +Durable stainless steel construction with a matte finish
  • +Wide opening makes cleaning and adding ice easy

Watch-outs

  • Soft plastic cap layer may be prone to blemishes over time
  • Some parts can be hard to take apart for cleaning
  • Taking a swig from two outlets feels strange at first

How it compares

The Owala FreeSip uniquely offers both sip and swig drinking without switching caps, a feature absent in the Hydro Flask and ThermoFlask. While it provides good insulation, it's less durable than the YETI Rambler and lacks the 32 oz capacity of the Klean Kanteen and Simple Modern. Unlike the Iron Flask, it doesn't offer interchangeable lids, and its plastic cap layer may degrade over time, making it less ideal for heavy use compared to the more robust Stanley or Yeti options.

ThermoFlask Double Wall Vacuum Insulated 32 oz
#1 · Top Score

ThermoFlask Double Wall Vacuum Insulated 32 oz

The ThermoFlask offers excellent dishwasher safety and cup holder compatibility, features not found in the Iron Flask or Simple Modern. It provides good insulation comparable to the Klean Kanteen and Simple Modern, but lacks the eco-friendly recycled materials of the Klean Kanteen and the versatile lid options of the Hydro Flask. Unlike the YETI Rambler, it's more affordable but less durable, and it doesn't offer the dual-drinking functionality of the Owala FreeSip.

Simple Modern Summit Water Bottle 32 oz
#2

Simple Modern Summit Water Bottle 32 oz

The Simple Modern Summit offers the best value among all competitors, with affordable pricing and good insulation, unlike the premium-priced YETI Rambler or Iron Flask. It provides interchangeable lids and leakproof straw functionality, features not found in the ThermoFlask or Stanley IceFlow. However, it's less durable than the Klean Kanteen and lacks the eco-friendly recycled materials of the Klean Kanteen and the superior insulation performance of the Klean Kanteen and ThermoFlask, making it less ideal for serious outdoor use.

Hydro Flask Wide Mouth 24 oz
#3

Hydro Flask Wide Mouth 24 oz

The Hydro Flask Wide Mouth 24 oz stands out with its wide mouth design and multiple lid options, making it more versatile than the Klean Kanteen TKWide or Iron Flask, which have more limited lid configurations. While it offers excellent insulation, it's less durable than the YETI Rambler and lacks the eco-friendly recycled steel construction of the Klean Kanteen. Its 24 oz capacity is smaller than most competitors, making it less ideal for extended outdoor use compared to the 32 oz models from ThermoFlask and Simple Modern.

Iron Flask Sports Water Bottle 32 oz
#4

Iron Flask Sports Water Bottle 32 oz

The Iron Flask offers a lightweight design and three interchangeable lids, features not found in the ThermoFlask or Simple Modern. It's more affordable than the YETI Rambler and provides versatility for both hot and cold beverages, unlike the Stanley IceFlow which is limited to cold drinks. However, it's less durable than the Klean Kanteen and lacks the superior cold retention of the Klean Kanteen and Simple Modern, making it better for casual use rather than heavy-duty outdoor applications.
