Frequently Asked Questions

Does it work under a wide-brim farming hat?

Yes. The insert is flexible and conforms to the crown of any hat, including wide-brim straw hats, bucket hats, and baseball caps commonly worn in agriculture. It stays in place without clips or adhesives and does not change how the hat fits on your head.

How do field workers recharge inserts without electricity?

Pack frozen inserts in a high-quality cooler with ice at the start of the day. A standard hard cooler with ice can keep inserts frozen for 8-10 hours in the field. Some farms use a rotation system where inserts are brought out with morning water and lunch deliveries.

Is it OSHA-compliant for agricultural settings?

Yes. The insert is a passive cooling device with no electronics or chemicals, and it does not modify any PPE. It supports OSHA's Heat Illness Prevention Campaign recommendations for cooling measures and is appropriate for use alongside all standard agricultural safety equipment.

Can it withstand dust and dirt exposure?

The insert is sealed and has a smooth, wipeable surface. Dust, dirt, and soil will not penetrate or damage it. After a day in the field, simply wipe it down with a damp cloth before placing it back in the freezer for the next use.
