Pro Tool Reviews tested Yeti LoadOut KOR Protective Inserts with a wheeled GoBox 28 and found they could hold varied gear in place and cushion ordinary transport. The review also found limits: the inserts are size-specific, require a pump, cost extra and cannot guarantee protection from severe impacts.
Pro Tool Reviews has published a hands-on review of Yeti LoadOut KOR Protective Inserts, testing whether the inflatable, shape-conforming inserts can protect tools and sensitive equipment in a LoadOut GoBox. The reviewer found they could keep different items stable during truck transport, but said they are not a guarantee against severe impacts and work only with the GoBox size for which they are made.
The inserts use a durable outer skin filled with cushioning beads. To fit equipment, the user places the insert in the GoBox, opens its valve and nests gear between its layers. After folding the top layer over the equipment, the user pumps air out until the insert feels rigid. Reopening the valve lets air back in so the insert can be reshaped. The source does not identify what the beads are made of.
In the review’s tests, a range of meters—including a non-contact voltage tester, voltmeters and a vehicle scanner—as well as binoculars, a flashlight and a Bluetooth speaker stayed in place while being driven in the back of a truck. The reviewer also struck a glass jar inside an insert with a pry bar and reported no visible damage to the jar or the insert’s exterior. These are one reviewer’s tests, not a controlled durability or certification assessment.
A more severe test had a different outcome: a thin glass placed in the GoBox broke after the box was kicked down dock stairs. The insert was not punctured by the shattered glass, and the box had only marks from the composite boards, but the test showed that the system cannot prevent damage under every impact. The reviewer cautioned against treating the inserts as protection from abusive handling.
Protection for Tools in Transit
For tradespeople carrying test instruments or other delicate gear, items shifting in a vehicle can lead to damage, downtime or repair costs. The review suggests the KOR inserts may help by holding differently shaped equipment in place and cushioning routine movement, including on a work truck. That makes them a potential alternative to fixed foam cutouts when the gear carried changes.
That flexibility comes with practical limits. Buyers need the matching GoBox size, must use a pump to remove air, and need to pack the box so equipment is surrounded rather than left with open space above or alongside it. The review describes the inserts as expensive but gives no price, so readers cannot use this report alone to compare their cost with other protective storage options. Most importantly, the tests do not establish protection against hard drops or other severe impacts.

How the Inserts Fit GoBoxes
The KOR inserts are an accessory for Yeti LoadOut GoBoxes. According to the review, each set is made for a particular GoBox size; the sets are not interchangeable with other GoBox sizes or Yeti coolers. Their design uses two layers that conform around packed items when air is removed, rather than rigid compartments tailored to one tool.
In its practical advice, the review says to keep gear away from the GoBox edges and to pump the inserts until items cannot shift. Leaving excess air may allow equipment to move and strike other objects. For taller gear, the reviewer found two single-layer inserts easier to position than the connected double-layer arrangement. The source also notes that the wheeled boxes have wheel wells, but the supplied text cuts off before completing its related packing advice.

Limits of the Test Evidence
The review does not report a formal test protocol, measured impact levels, long-term wear results or a comparison with competing inserts. It also does not identify the cushioning beads’ material or provide a price. The reported truck ride and impact demonstrations offer examples, but do not establish how the inserts would perform with every instrument, load arrangement or jobsite incident.
It is also unclear from the supplied source how the inserts perform in repeated daily use, whether the pump is included with each set, and how well they hold their shape over time. The review’s glass test shows a boundary, not a universal threshold: it does not specify the force of the impact or establish what other equipment would withstand.
Check Fit Before Buying
Readers considering the inserts should confirm their LoadOut GoBox size and assess whether the equipment they carry can be packed with the inserts fully around it. The reviewer’s advice is to position gear away from the box edges, remove enough air to prevent movement and account for taller items that may be easier to secure with two single-layer inserts. A pump is part of the practical setup, so users should check what is included and plan to have it available.
No follow-up test, price update or additional product announcement is included in the source material. The review therefore leaves buyers with a hands-on indication of how the inserts performed in one set of trials, rather than a guarantee of jobsite protection. Their usefulness for a particular trade will depend on the gear, box size, packing method and expected handling.
Key Questions
Are Yeti LoadOut KOR Protective Inserts made for every GoBox size?
No. The review says each insert set is specific to one LoadOut GoBox size and is not interchangeable with other sizes or coolers.
Can the inserts keep tools from moving during truck transport?
In the reviewer’s tests, meters and several other items stayed in place during a truck ride. That is a report of those tests, not a guarantee for every load or road condition.
Do KOR inserts protect gear from hard impacts?
Not reliably in every case. A glass broke in the review’s dock-stair test, and the reviewer warned that gear could still be damaged by sufficiently hard impacts.
How are the inserts fitted around equipment?
Users place gear between the insert layers, fold the top layer over it, close the valve and pump air out until the insert feels rigid. Opening the valve lets air back in for reshaping.
What drawbacks did the review identify?
The review called the inserts expensive and said users must remember to bring the pump. It also advised packing carefully so equipment does not shift or sit too close to the GoBox edges.
