Premium 3-Pack Hat Sweat Liners – Reusable, Absorbent, No Glue Hold – Fits Any Hat with Sweatband – Golf, Work, Sports Black

These are the best of what's available for blocking sweat from your hats. You don't have to deal with the useless "tape" that most have and it's reusable so don't let the higher price steer you away. I own enough for all my hats. I remove them if I've sweat a lot and I rinse them with water and set them aside to dry for next wear. So easy. If you wear XL hats like I do these fit PERFECT. If you wear S/M/L "normal" size hats or "one size" adjustable hats, you'll likely want to trim the ends for a better fit. I tuck them in nicely (the hat must have an inner band for these to work) and they never move, even when I remove my hat several times. They've held up for several months now. Also, they are quite comfortable on your forehead, not harsh or scratchy at all. And my hats all look great...NO sweat rings! Along with some Scotchgard I don't worry about stains anymore.

The other reviews cover the need to adjust it in the hat a bit and that it requires opening up the hat a size. It works very well for what it is intended. However, you probably sweat a bit if you are reading this as I do. It holds a finite amount of sweat before you are back to having to catch the drips. Bringing extras with you certainly help. May be a little costly, but wash/dry/reuses well.

After lots of research of reviews this product seemed to be the Best solution. I like how you can customize the fit of this product. For my first hat the best fit was achieved by trimming the inside liner (the white part) by about 1/8" this allowed for the black side to come down further toward the edge of the cap. I am sure I am going to appreciate the ability to occasionally remove and wash them. They are much lighter weight than I expected and the inner liner is not a hard plastic like I thought it was but more of a thin foam. Im sure this will help it stay in place. Looking forward to the next hot day to give these a full test. I have a lot of hats so these will allow me to switch them from hat to hat. Cant do that with one that is held in place by adhesive.

Not sure how I feel about this sweat liner yet. The overall thickness is a little over 1/8”. The EV foam piece that provides the “shape” is unnecessarily thick IMO. Combined with the absorbent sweat pad, it creates a noticeable gap at your forehead. The sweat pad is thick and has an impermeable backing that prevents moisture from reaching your hat. This is good design, but problem for me is that is that the thickness messes with the fit no matter how I adjust the SnapBack. On the plus side, it works and the design allows it to stay in place. I’d like to see a much thinner foam layer or some other substrate to reduce the thickness, especially for hats like mine that already have structured panels in the front that don’t require shaping. Good concept, needs some refinement.

These hat sweat liners really work. My husband always ruined his hats in the summer from sweating. But not with these. I would highly recommend them

These work well and stay in place. Keeps my hats from getting nasty from sweat.

I'm very pleased with these hat liners. They are a bit pricey, but since they are washable and reusable they are a decent value. I've always hated it when my hats would get that dark, wet sweat band in front, sometimes so bad that it extended out on to the brim. Though I haven't yet tried these bands out under the most extreme conditions, so far they have managed to keep my hats dry. They absorb a significant amount of moisture, they dry quickly, they are thin enough that my favorite non-adjustable hat still fits with one of these in it, and they stay in place. I don't know if they will perform as well after being washed. If so, my rating will be upgraded to 5 stars.

This product is amazing. I'm a golf pro and wear hats everyday. I'm out in the heat during the golf season and ruin all my hats with sweat and have to purchase more which can be expensive. I bought a pack of these and they can be inserted in seconds and keeps my hat clean and in shape. The are so durable and comfortable and I don't realize I have it inserted. I can just move them from one hat to the other in seconds. I haven't tried to wash them yet, but I guess they're washable. If you love hats like I do, this product is a must have.
