Three ZONE3 tow floats compared by specification (not tested)
Compare the published storage, dimensions and access details of three ZONE3 tow floats, with practical tradeoffs and clear limits. Not tested.
Specification-based assessment — not tested. We haven't tested these; specs are manufacturer-stated (checked 2 November 2026). This comparison covers three named ZONE3 designs to show how storage and access change the buying decision. It is not a market-wide ranking. No prices, scores or affiliate links are included.
Our tow-float explainer covers general setup and limitations. Here, the question is narrower: which published design matches the belongings you intend to carry? Product names containing “Safety” are the manufacturer's names, not a Tarnbay assurance.
Three designs, three different jobs
| Model | Manufacturer-stated detail | Question before buying |
|---|---|---|
| Recycled Swim Safety Buoy / Tow Float | 49 × 30 cm deflated; waist leash, handle and reflective strips | Do you need a storage compartment? The checked feature list does not specify one. |
| Recycled Safety Buoy/Dry Bag 28L | 28L stated capacity; 72 × 37 cm deflated; two air bladders around storage | Can you pack your actual items and close it exactly as instructed? |
| Recycled On The Go Swim Buoy | 4L dry-bag capacity and 10L float volume; accessible central storage | Can the contents tolerate the maker's stated water-protection limitation? |
Recycled Swim Safety Buoy / Tow Float
ZONE3's model page lists the deflated dimensions, reflective strips, carry handle and waist attachment. It does not specify usable storage in the checked feature list. Do not assume that an inflatable shape has a dry compartment.
Assessment: this is the first design to investigate if storage is unnecessary. Its smaller published flat dimensions may help when comparing space in your kit bag, but flat size does not establish packed size, towing resistance or comfort. Ask the maker about belt adjustment if fit is uncertain. We cannot judge visibility at distance or behaviour in waves from the specification.
Recycled Safety Buoy/Dry Bag 28L
ZONE3 states a 28L capacity, dual air bladders surrounding the storage section, an adjustable dual belt and reflective logos. Its listed deflated dimensions are larger than the basic model's.
Assessment: investigate this design when carrying clothing is central to your plan. The storage arrangement is a meaningful distinction from the basic float; the capacity label alone cannot establish whether a particular towel, shoes and layers fit once the closure is secured. Confirm permitted contents and loading instructions before buying. We have not checked leakage, seam durability or how a loaded bag tows, and cannot translate its stated capacity into a recommended load.
Recycled On The Go Swim Buoy
ZONE3 lists separate figures of 4L for the dry bag and 10L for float volume. Its central compartment is designed for access while swimming. Crucially, the maker says the dry bag is not fully waterproof and recommends an additional waterproof pouch for electronic valuables.
Assessment: access to a few small items is the reason to investigate this model. It is a different purchase from a clothes-carrying bag. Do not read the 10L float figure as 10L of storage, or interpret “dry bag” as an immersion guarantee. We cannot assess how easily a particular swimmer reaches or closes it on the water. Practise according to its instructions before relying on the arrangement.
What these specifications cannot settle
These are design assessments, not evidence of performance. We have no comparative measurements of drag, leakage, visibility, strap comfort or long-term durability. Check the exact model and current instructions: older versions and similar names can have different details. No product photographs are used because we have not licensed manufacturer imagery; a generic illustration would not demonstrate these models.
A tow float does not replace a lifejacket, companion, suitable conditions or a way to call for help. Follow the RNLI's open-water swimming guidance and the cold-water guide. Equipment choice does not change access rules: England, Wales, Scotland and Northern Ireland have different arrangements, explained in our four-nation access guide. Follow the venue's own equipment requirements and local notices.
