EP4 Sonic Defenders® Plus protect your hearing without interfering with your ability to hear routine sounds or conversations. Their triple-flange stem design fits larger ear canals and provides a Noise Reduction Rating (NRR) of 19dB. Sounds, at safe levels, are allowed to pass through into the ear canal, while potentially harmful noises (above 85dB) are greatly reduced via a proprietary design that incorporates the patented Hocks Noise Braker® filter. EP4s include attached stopper plugs, which can be inserted to block out lower-level noise like that heard on a plane, or in situations where hearing ambient sound or conversations isn't critical, such as when trying to sleep. The right/left color-coded Sonic Defenders Plus are made from a soft but durable, hypoallergenic polymer and are ergonomically shaped, with an adjustable-stem design, providing a secure fit, all-day comfort, and extended product life (3 to 6+ months, depending on usage and care). And their low-profile design means they can be worn while wearing a helmet or mask or while using a phone or headset.EP4 Sonic Defenders Plus are sold in single left/right sets in a box containing 25 sets in small, medium, and large. Each set is packaged in a convenient carry case. Medium EP4 Sonic Defenders Plus fit most people with larger ear canals comfortably. Sizing is based on the size of the ear's Helix Bowl. Consult Sizing Chart for proper fit.
For those who do not have larger ear canals, double-flanged EP3 Sonic Defenders may provide a better fit.
Please Note: We cannot ship Surefire products outside the United States.

Perfect Everyday Cap – Cute, Comfortable, and Sporty
Size: One Size, Color: Wonder Alumina Grey/Off White/3
I really love this adidas Women’s Sport Essentials Baseball Cap! It’s lightweight, comfortable, and fits perfectly without feeling too tight. The adjustable strap makes it easy to get the right fit, and it stays secure even when I’m active or on the go.
The design is simple but stylish, and it goes with almost any outfit—great for casual wear, workouts, or sunny days. It also does a good job keeping the sun out of my face without feeling heavy or hot.
Overall, super cute, practical, and great quality. Definitely a staple cap I reach for all the time!

Adidas Classic Adjustable Cap – 2-Pack (Black & White)
Size: One Size, Color: Black/White/2, Size: One Size, Color: Black/White/2
I recently purchased this Adidas cap set, and I’m extremely happy with both the quality and the comfort. The material feels durable yet lightweight, making it perfect for everyday use or outdoor activities. The adjustable strap ensures a perfect fit, and the classic Adidas logo gives it a clean, sporty look.
Both colors look great — the black one is sleek and versatile, while the white one is fresh and stylish. They keep their shape well, even after multiple uses. Overall, this is a great purchase for anyone looking for a comfortable and well-made cap. Highly recommended!
