The Hydro Flask Wide Flex Cap is a 40 oz stainless steel water bottle with double-wall vacuum insulation and a flexible-handle cap.

## Before you buy

- The listing labels capacity as "1.13 kg" while the title and feature copy call it 40 oz. These units describe different quantities, so the capacity field is inconsistent. Confirm the intended capacity before buying. Temperature-retention times are manufacturer claims, not independently verified. Use only as directed. The manufacturer says not to use it on a stove, in a microwave or freezer, and to keep hot drinks out of children's reach.

## In the box

- Water bottle (Included)

## A good fit for

- Adults wanting a large reusable bottle for water and fewer refills.
- Buyers who value a wide opening for adding ice and dishwasher-safe care.
- People who want a handled cap and claim of temperature retention for both cold and hot drinks.

## Less suited to

- Buyers prioritizing a small, lightweight bottle for compact bags.
- Anyone who needs verified capacity in volume units without resolving the listing's inconsistent capacity entry.

## Customer feedback

Customer feedback is generally favourable about quality, cold-water retention, colour and appearance, with some also liking the size. Reports are not uniformly positive: rusting around the lip and quick staining are mentioned, while durability and leakage experiences vary. Those concerns matter for a bottle advertised as stainless steel and leakproof when closed, so the listing claims should not be taken as assurance against the reported issues.
- Positive themes: Customers describe good quality and say water stays cold for a long time.
- Positive themes: Colour and appearance receive positive mentions.
- Negative themes: Some customers report rusting around the lip and staining quickly.
- Mixed feedback: Customers report varied experiences with durability and leakage.

## Frequently asked questions

### How much does this bottle hold?
The title and feature copy describe a 40 oz bottle, but the technical capacity field says "1.13 kg," a mass unit. The listing is inconsistent, so confirm the capacity with the selected listing before purchase.
### How long does it keep drinks hot or cold?
The manufacturer claims up to 24 hours cold and up to 12 hours hot using double-wall vacuum insulation. These are stated claims, not independently verified performance.
### Is the cap leakproof?
The listing says the Flex Cap is leakproof when closed. It does not make that claim for an open or incompletely closed cap.
### Can the bottle go in a dishwasher?
The manufacturer says both the bottle and lid are dishwasher safe. It also says not to use the bottle on a stove, in a microwave or freezer.
