Good to know
  These shorts use silver fiber shielding fabric — a different technology than the Ultra Armor® used in DefenderShield’s device cases. The silver fiber lining covers the entire short from waistband to hem and blocks wireless RF radiation (up to 40 GHz) from reaching the body areas it covers. Areas below the hem and above the waistband are not shielded. Your phone remains fully functional in the pockets — calls, texts, and notifications come through normally. The silver fiber is naturally anti-microbial and anti-odor, reducing the need for frequent washing.
Overview

Shield Your Lower Body from Wireless Radiation

🛡 100% Silver Fiber Shielding Lining — up to 40 GHz

The middle layer of these shorts is a continuous lining of 100% silver fiber shielding fabric. Silver is highly conductive — when woven into fabric, the fibers form a dense conductive mesh that reflects and absorbs wireless RF radiation before it reaches your skin. The shielding covers your upper thighs, groin, and reproductive organs from waistband to hem. The frequency range — up to 40 GHzno batteries, no charging, no activation. Put the shorts on and the lining works.

Three Layers Built for Comfort Against Skin

🧵 Modal + Silver Fiber + Viscose — Soft, Breathable, Antimicrobial

The outer shell (60% Modal / 40% Nylon) is soft, stretchy, and breathable — it looks and feels like standard loungewear. The middle lining (100% silver fiber) provides the RF shielding and is naturally anti-microbial and anti-odor, so you can wear the shorts multiple times between washes. The inner lining (100% viscose) sits directly against your skin with a smooth, gentle finish. The result is a three-layer garment that shields, breathes, and stays fresh.

Wear Them Anywhere You Use Your Devices

🏠 Lounging, Sleeping, Working from Home, Travel

Designed for the situations where your lower body is closest to wireless devices for extended periods. Working from a laptop on the couch. . Commuting on a train or plane surrounded by other passengers’ devices. Relaxing at home near WiFi routers and Bluetooth speakers. The roomy side pockets also place a layer of shielding between your phone and your body when you carry it in your pocket.


Layer with Other DefenderShield Clothing for Full Coverage

🧥 Shorts + Jacket + Hat + Scarf + Gloves = Head-to-Knee Shielding

Each DefenderShield garment shields only the body area it covers. The shorts shield your lower body; for upper body coverage, add the EMF Hooded Jacket (torso, head). For neck coverage, add the Wrap Scarf. For hands, add the EMF Gloves. For head coverage, choose from three EMF hats. For laptop use on the lap, pair these shorts with the DefenderPad for additional heat and ELF-blocking functionality that silver fabric alone does not provide.

How to use

Getting Started

1. Check your size. Measure your waist circumference with a measuring tape and compare against the size chart below. If you are between sizes, size up for a more relaxed fit.

2. Put them on. The shorts have an elastic waistband — pull on like any pair of lounge shorts. The shielding lining sits between the outer shell and the inner lining. You do not need to position or adjust anything. The silver fiber layer covers the entire interior from waistband to hem.

3. Use the side pockets. Slide your phone into a side pocket for shielded carry. The silver fiber lining extends into the pocket area, placing a layer of shielding between the phone and your body.

Maximizing Shielding

• The shorts shield what the fabric covers. Your upper thighs, groin, and reproductive organs are shielded from waistband to hem. Areas above and below the shorts are not shielded.

• For laptop use, pair with the DefenderPad. The shorts block wireless RF radiation from passing through the fabric to your lap. However, they do not block Extremely Low Frequency (ELF) emissions from your laptop’s battery and power supply, and they do not block heat. The DefenderPad Laptop Shield adds ELF and heat shielding for direct laptop-on-lap use.

• Wear during sleep for overnight shielding. The shorts provide continuous passive shielding while you sleep — useful if your bedroom has strong ambient WiFi, or a nearby cell tower.

Care Instructions

• Minimize washing. Silver fiber is naturally anti-microbial and anti-odor, so frequent washing is not necessary.

• When needed, gentle handwashing is recommended. Use lukewarm water below 30°C (86°F) with a neutral laundry detergent. Spot cleaning is ideal for minor blemishes.

• Do not bleach. Do not machine wash or machine dry. Do not tumble dry.

• Air dry only. Lay flat or hang to dry.

• Avoiding machine washing and drying helps maintain the integrity of the silver fibers, preserving shielding effectiveness over time.

FREQUENTLY ASKED QUESTIONS

EMF Radiation Protection Shorts FAQ

Upper thighs, groin, and reproductive organs — from waistband to hem. The 100% silver fiber lining covers the full interior of the shorts, including the side pocket area. Areas above the waistband and below the hem are not shielded. For upper body coverage, see DefenderShield’s EMF Protection Clothing lineup.

No. Phone cases use Ultra Armor or Ultra Armor+® — rigid composites designed for device-level shielding. These shorts use silver fiber fabric designed to be soft, flexible, breathable, and wearable against skin for extended periods. Both block wireless RF radiation, but the materials, frequency ranges, and applications are different.

300 Hz to 10 GHz. That range covers WiFi, Bluetooth, cellular, and low- to mid-band 5G signals. The shorts do not cover high-band mmWave 5G (24 GHz+). For broader frequency coverage, see DefenderShield’s device cases and laptop shields, which use Ultra Armor shielding technology.

Yes — your phone works normally. The silver fiber lining extends into the pocket area, placing a layer of shielding between the phone and your body. Calls, texts, WiFi, Bluetooth, and notifications remain fully functional. The shielding reduces RF radiation passing through the fabric toward your body, not the phone’s ability to transmit.

No. The silver fiber lining blocks wireless RF radiation (300 Hz–10 GHz) but does not block Extremely Low Frequency (ELF) emissions from a laptop’s battery and power supply, and it does not block heat. For laptop-on-lap use, pair these shorts with the DefenderPad Laptop Shield, which adds ELF and heat protection.

Measure your waist circumference and compare against the size chart. The shorts come in unisex cuts, each in Small, Medium, and Large. If you fall between sizes, size up for a more relaxed fit. The elastic waistband provides flexibility within each size range.

Less often than standard clothing. The 100% silver fiber lining is naturally anti-microbial and anti-odor, so frequent washing is not necessary. When needed, gentle handwashing in lukewarm water below 30°C (86°F) with a neutral detergent is recommended. Do not bleach, machine wash, machine dry, or tumble dry. Air dry only. Avoiding machine washing preserves the integrity of the silver fibers and maintains shielding effectiveness.

The shorts are designed primarily as lounge and sleep wear. They can be worn during light activity, but the three-layer construction is heavier than standard athletic shorts. The silver fiber lining is naturally anti-odor, which helps during moderate activity.
