A colorful and reliable water bottle will be an excellent approach to encourage your children to drink enough water. Thermos 12-ounce Funtainer (which comes at a price range of $14-$18) is a robust, safe, and economical bottle for children of all ages. Even more, it has a built-in straw.

This portable and small bottle is available in a variety of kid-friendly designs and colors. Though the Thermos 12-ounce Funtainer has a capacity of just 12 ounces, it is the ideal size for little hands. This bottle fits comfortably into the majority of school bags and lunchboxes. Furthermore, the Thermos bottle is made of BPA-free stainless steel and is both lightweight and very sturdy. Its click-shut cap is simple to operate and completely leakproof when closed correctly.

Ranking second on our list is the CamelBak Chute Mag bottle (which is about $30). This bottle has an unusual top design yet performs well. Its cap is a screwed lid that swings open to conceal a magnet.

If you are a multitasker looking for a bottle that opens easily with one hand (and thus, eliminates the possibility of losing and misplacing your cap), then this bottle may be for you. As an added bonus, the cap fits a variety of different CamelBak bottles.

Despite the cap style, this bottle is lightweight and quite robust, particularly while traveling. Also, the CamelBak Chute Mag is constructed of 18/8 stainless steel and has a BPA-free magnetic top. While reviewers laud the bottle's ability to retain cool ice and water, others noted that it is prone to leaking. But all in all, this is an excellent investment in our opinion, due to the incredible volume it offers at this price range.

Are you looking for the best insulated water bottles to buy? If that is the case, then we are certain that Hydro Flask Standard-Mouth will not disappoint you. Indeed, the Hydro Flask Standard-Mouth ($35) was rated the best insulating bottle overall, with a 4.7-star rating across 1,180 reviews.

The brand's double-wall insulation and professional-grade stainless steel are meant to keep your drinks cold for hours without affecting their flavor.

As one user wrote in his review, the Standard Mouth is quite durable and still performs well.

Reviewers laud this bottle's superior insulation and diverse color palette of over ten vibrant hues. Furthermore, it can accommodate most holders and pack compartments due to its slimmer profile. While it is also available in 18 -ounce and 21-ounce versions, we find that the 24-ounce edition is the most convenient for most activities.

Another fantastic insulated bottle - which deserves to make its way onto our list of the best insulated water bottles to buy - is none other than the YETI 18-ounce Rambler Bottle. This variant comes at a rather affordable price of 30$. The reason we decided to pick it for our list is because this bottle enjoys a stainless steel structure, superior insulating properties, and reasonable pricing. Another major competitive edge is that this bottle is significantly heavier compared to other models, which provides it a huge step-up in terms of longevity.

The cap design, convenience of sipping, and resistance to leaks were the only areas of contention among testers – some like the cap, while others despise it. It is all about specific preferences, so consider these aspects carefully before making your purchase.

This YETI 18-ounce Rambler bottle received the most 5-star reviews across review websites - and is an excellent value for the price. Indeed, it was among the top contenders when it comes to longevity, dings, and deterring dents.

GSI Outdoors has devoted an entire subsection of its website to insulated products. However, the GSI Outdoors MicroLite 500 is still the brand's finest insulated bottle to date. The "500" in its name refers to the 500mL capacity; however, it is also available in a 750mL/24-ounce capacity.

The GSI Outdoors MicroLite 500 (which comes at $28) is also our pick for "one of the best options for hot contents" - it really stays true to the leakproof standard that we all want. We do not have quantitative evidence, but hot beverages remain boiling in this bottle - AND it seems most reviewers concur with us. (And, in case you were wondering, the cold stuff remains cold as well.)

While the flip cap has a somewhat more sophisticated construction, it is also really useful for traveling, and we feel it is a very pleasant feature. Also, the lock mechanism is effective; it prevents the bottle from unintentionally opening and spilling its contents while it is in your backpack. One thing to keep in mind is that you may need to carefully clean the inner cap between usage and beverages.
