# Coolflask 64 oz Insulated Stainless Steel Water Bottle

The Coolflask insulated water bottle is a large-capacity stainless-steel jug supplied with straw and spout lid options. Its half-gallon size and carrying strap suit buyers who want fewer refills, though the weight and mixed reports about strap durability and leakage are worth considering.

## At a glance

- Two lid styles are listed: a straw lid for sipping and a spout lid for drinking directly.
- The listing claims cold retention for 48 hours and hot retention for 24 hours.
- The product description advertises a shoulder strap for carrying.

## Pros

- The two lid options give buyers a choice between straw sipping and a spout.
- The stated half-gallon capacity can reduce refill frequency for people who need to carry a large drink supply.
- The listing describes double-layer stainless-steel vacuum insulation.

## Cons

- A filled half-gallon bottle is a substantial item to carry, so its size may be less convenient for compact bags or light travel.

## Before you buy

- The title claims 64 oz capacity, while the details field lists capacity as "4 pounds," which is a weight rather than a volume. The listed 5-inch width and 10-inch height may also not establish the overall size of this large-capacity jug. Care instructions say both "Dishwasher Safe" and "Hand Wash Only." Confirm capacity, cleaning guidance, and dimensions for the selected listing before buying. The stated temperature-retention and leak-proof performance are listing claims, not independently verified results.

## A good fit for

- People who want a large insulated bottle and prefer choosing between straw and spout lids.
- Buyers who value a carrying strap and are comfortable transporting a bulky bottle.

## Less suited to

- Anyone prioritizing a compact, lightweight bottle or relying on the strap for rough or frequent carrying.
- Buyers who need confirmed dishwasher-only or hand-wash-only guidance, or an unambiguous capacity specification.

## Customer feedback

Customer feedback highlights perceived build quality, temperature retention, appearance, portability, and the carrying strap. Some customers report cold drinks lasting up to 48 hours, which aligns with the listing's claim but does not verify it. Strap durability and leakage receive mixed comments, so buyers carrying a full, heavy jug should weigh those concerns against the convenience of its large stated capacity. Aggregate ratings lean positive overall, but do not resolve these specific mixed experiences.
- Positive themes: Customers report positive impressions of build quality and temperature retention.
- Positive themes: Customers mention the appearance, portability, and carrying strap favorably.
- Mixed feedback: Feedback is mixed on strap durability, including reports of breakage as well as sturdiness.
- Mixed feedback: Reports differ on whether the bottle leaks.
