HOLLOW-FIBER WATER FILTRATION

More than an outdoor company. Pioneered hollow-fiber water filtration, with 25M+ lives served clean water since 1984.

Sawyer Products was founded in 1984 in Safety Harbor, Florida. It started with a snake venom extraction kit and a chemical-protection line for serious outdoor use. A chance encounter brought them to hollow-fiber membrane filtration originally developed for kidney dialysis, and the rest of the company's mission rewrote itself. Today their 0.1-micron filters are rated for up to 100,000 gallons each, and through the Sawyer Foundation and 140+ charity partners across 80 countries, Sawyer reports more than 25 million lives served clean water.

Shopping with SRO

How long does shipping take?

Most in-stock orders are processed within 1 to 3 business days, not counting weekends and federal holidays. Special-order, dealer-direct, custom, and LYNX Survival Systems orders can take longer. Lead times shown on product pages are estimates, not guarantees.

Typical carrier transit after that: Economy 5 to 7 business days, Expedited 2 to 3, Overnight 1. These are carrier estimates, not guarantees. Some items, such as lithium batteries, aerosols, and safety matches, may be limited to ground shipping.

Free Economy shipping on qualifying orders over $150 to the contiguous US, on eligible products. Oversized, heavy, freight, hazardous-material, dealer-direct, custom-built, and special-order items may be excluded. Oversized and freight items, such as rooftop tents, recovery equipment, and Pro Eagle products, may carry extra shipping charges. If extra charges apply, we'll let you know before the order ships.

Some items ship directly from the manufacturer or a supplier partner on their own schedule, so an order can arrive in more than one package with more than one tracking number. Full details: Shipping Policy.

What’s your return policy?

You have 30 days from receiving your order to request a return on eligible items. Email info@stayreadyoutdoors.com with your order number, the item, and the reason, and wait for return authorization before you ship anything back. Returns sent without authorization may be refused.

Items must come back in like-new condition: unused, unmodified, unworn, unwashed, and free of odors, dirt, stains, pet hair, and damage, with all original packaging, manuals, accessories, and tags, plus proof of purchase.

For standard parcel items, you pay return shipping unless the return is due to our error, shipping damage, or a verified defect. If we provide a prepaid label, its cost may be deducted from your refund. For oversized, freight, dealer-direct, and special-order items, you pay return shipping unless the item arrived damaged, defective, or incorrect. Original shipping charges aren't refunded. Some items may carry a restocking fee of up to 15%, and we'll tell you during authorization.

Some items are fulfilled by third-party suppliers and follow that supplier's return policy, so eligibility, refund timing, return shipping, and restocking fees may differ.

Approved refunds go to your original payment method. Allow up to 10 business days after approval, and your bank may take longer to post it. Full details: Return & Refund Policy.

What can’t I return?

These can't be returned or refunded, except where the law requires it:

  • Engraved, personalized, customized, and built-to-order products, and special-order products obtained specifically for you
  • LYNX Survival Systems survival kits, custom IFAKs, and custom medical kits
  • Agency, government, organizational, and contract-built orders
  • Gift cards, and sale or clearance items marked final sale
  • Food, drink, and other perishable products, including emergency food
  • Personal care, hygiene, and beauty products
  • Hazardous materials, and flammable liquids or gases
  • Opened or used medical products

Not sure whether an item qualifies? Email info@stayreadyoutdoors.com before you order.

Do you ship outside the contiguous US?

Alaska, Hawaii, Puerto Rico, Guam, and other U.S. territories aren't eligible for free shipping, and extra freight charges may apply. If your order needs a shipping quote, we'll contact you before it ships. If you decline the quote, the order may be canceled and refunded. APO/FPO addresses are also excluded from free shipping.

International shipping is available on select products and destinations, and some products may be restricted from international shipping. You're responsible for import duties, taxes, customs fees, brokerage fees, and meeting your country's import rules.

Full details: Shipping Policy.

My package arrived damaged. What now?

Inspect your order when it arrives. If anything is damaged, defective, or wrong, email info@stayreadyoutdoors.com within 7 days of delivery (5 days for food and drink) with your order number, a short description, and photos of the item and the packaging.

You don't pay return shipping on items that arrived damaged or wrong, or with a verified defect. Some items fulfilled by third-party suppliers follow that supplier's policy instead. Reporting after 7 days may limit our ability to pursue a claim with the carrier, and while we may help with a carrier claim, approval is up to the carrier.

Package lost or never arrived? Contact us within 7 days of the expected delivery date. For freight deliveries, inspect the shipment before you sign and note any visible damage on the carrier's delivery receipt.

Can I talk to a human before buying?

Yes. Call (562) 294-6269, Monday to Friday, 8:00 AM to 4:00 PM Pacific time, or email info@stayreadyoutdoors.com. We reply within one business day.

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. Current and former U.S. military, military spouses and dependents, and first responders, including law enforcement, fire, and EMS, can save up to 10% on most of our products through GovX ID.

Verify on our GovX discount page and you'll get a single-use code to enter at checkout. For later orders, log in with GovX ID for a new code (limit one code per day). The GovX code can't be combined with other discounts.

Important Use Notes

Sawyer's published removal ratings cover bacteria, protozoa and microplastics. They do not list viruses or chemical contaminants, so treat water by another method where those are a concern.
