WHY YOU’RE BUYING FROM STAY READY.
We aren’t the Amazon of survival. We’re a small, opinionated shop that carries gear we’d stake our own lives on — and we back every piece with real support.
Curated
Every brand we carry has been vetted in the field by our team. If it doesn’t pass our 30-day use test, we don’t stock it.
Authenticated
Factory-direct from authorized dealers. No grey-market, no refurb, no knockoffs. Your warranty is real.
Supported
Real humans on phone, text, and email — seven days a week. We carry this gear ourselves and we stand behind it.
American
HQ in California. Orders ship from our US warehouse. US-based customer care.
GOVERNMENT CONTRACT EDC
What the federal government orders — released to civilians. Specialty EDC since 1992.
CountyComm started in 1992 in Sunnyvale, California, designing and producing specialty gear for federal, state, and local government agencies. The catch: anything that doesn't get shipped to a contract ends up on their public storefront — which is how civilians end up with the same EDC, watches, and tactical kit that ships in agency loadouts. They also carry the full Maratac line. Every product runs through multi-iteration field testing before it goes out the door.

Answers, straight up.
Product-specific questions on the left. Shopping with SRO on the right. Both open-ended — hit us if we missed one.
How long does shipping take?
Most orders process within 1–3 business days from our warehouse. From there: 5–7 business days economy, 2–3 business days expedited, or overnight if you need it fast. Free economy shipping on orders over $150 (contiguous US). Alaska, Hawaii, and Pro Eagle / freight items are quoted at checkout. You’ll get a tracking number and link the moment your order ships.
What’s your return policy?
30 days from the day your order arrives. Gear has to come back unused, with all original tags, stickers, and packaging intact. For standard items we’ll send a prepaid return label and deduct return shipping from your refund. Oversized or freight returns are on you, unless the item showed up damaged, defective, or wrong — in which case we cover it.
Refunds hit your original payment method within 10 business days of approval.
What can’t I return?
Final-sale items, gift cards, food and drink products, personal-care items, anything customized or engraved, briefs (hygiene), and hazardous materials. If you’re not sure whether something qualifies, email us before you order — we’ll tell you straight.
Do you ship outside the contiguous US?
Yes. Alaska, Hawaii, and US territories ship on freight-quoted rates calculated after checkout. International orders are available worldwide at variable rates; duties and import fees are the customer’s responsibility. EU customers get a 14-day cancellation window per EU consumer law, on top of our standard return policy.
My package arrived damaged — what now?
Email info@stayreadyoutdoors.com within 7 days of delivery with your order number and clear photos of the damage (product + packaging). We’ll replace, refund, or ship a return label on us — no back-and-forth. Damaged, defective, or wrong-item claims never cost you shipping.
Can I talk to a human before buying?
Yes. Email info@stayreadyoutdoors.com — we answer every message ourselves, usually within a few hours during business days. We carry this gear, we use this gear, and we’d rather talk you out of a kit that doesn’t fit your mission than sell you the wrong one.
Do you offer a military/first-responder discount?
Yes. Active-duty and veteran military, police, fire, EMS, and medical first responders get 10% off every order. Verify through GovX at checkout — one-time, secure, and reusable across thousands of brands. Discount applies automatically once you’re verified.
