# ZactOnly MSPO03-BLACK Magnetic Gym Bag, 46oz Bottle Capacity

The ZactOnly MSPO03-BLACK magnetic gym bag is a compact sling-style carrier with a claimed magnetic attachment and space for a bottle up to 46oz. Its listed capacity is only 1.4 litres, so it is aimed at carrying a bottle and a few small essentials rather than a full gym kit.

## Before you buy

- Listing details are inconsistent: the title gives a size of 6 x 5.12 x 11 inches, while the dimensions field gives 15.2L x 13W x 28H centimetres. The listing also describes the fabric as water-resistant in some places and waterproof elsewhere, so the level of protection is unconfirmed. The claimed 46oz bottle capacity is not a guarantee of fit for every bottle shape.

## In the box

- Bag (Included)

## A good fit for

- Gym users who want to keep a bottle and small essentials close at hand, including on suitable fitness machine frames.
- People seeking a small, light carrier for workouts, walks or casual outings.

## Less suited to

- Anyone needing space for workout clothes, shoes or bulky equipment.
- Buyers who need a supplied water bottle or confirmed waterproof protection.

## Customer feedback

Customer feedback highlights the magnetic attachment, gym use, functionality and fit for a 750ml bottle, with a report of use for casual outings too. That feedback is relevant if you want a bottle-and-essentials carrier, though bottle fit can vary and the listing's 46oz capacity claim is not a universal fit guarantee. Aggregate ratings are mostly five-star, but they do not establish performance for every user or bottle.
- Positive themes: Customers report that the magnetic attachment holds well on fitness machine frames.
- Positive themes: Feedback describes the size as suitable for a 750ml bottle and the bag as useful at the gym and for casual outings.

## Frequently asked questions

### Is a water bottle included?
No. The listing explicitly says the water bottle is not part of the product.
### What size bottle does the bag claim to hold?
The listing claims capacity for bottles up to 46oz. It does not confirm fit for every bottle shape.
### Is the bag waterproof?
The specifications list it as water resistant, while other listing copy calls it waterproof. The actual protection level is therefore unconfirmed.
### How much can the bag carry?
The listed storage volume is 1.4 Liters, which is suited to a bottle and a few small essentials rather than bulky gym kit.
