Grayl Mission Bottle Sling
The Mission Bottle Sling is a MOLLE-clad cross-body carrier built to hold any Grayl purifier, and most water bottles up to 40oz. Dual cinch top closures keep the bottle secure on the move, and the holder adjusts for left or right, front or back placement so you can set it where it rides best.
Reinforced webbing straps with snap closures let it attach to any MOLLE-equipped pack, panel, or belt. A full-zip front pocket takes a large phone or essentials, and the sidewalls accept G-MOD pouches when you need more capacity.

HQ in California. Orders ship from our US warehouse. US-based customer care.
Answers, straight up.
Product-specific questions on the left. Shopping with SRO on the right. Both open-ended — hit us if we missed one.
Which Grayl bottles does it carry?
Any Grayl purifier, including the 24oz GeoPress and GeoPress Ti and the 16.9oz UltraPress, plus most standard water bottles up to 40oz.
How does it attach and adjust?
Reinforced webbing straps with snap closures mount it to any MOLLE pack, panel, or belt, and it also runs as a standalone cross-body sling. The bottle holder repositions for left or right and front or back carry, with several strap clip-in points to fine-tune where it sits.
What are G-MOD pouches?
Grayl's modular accessory pouches. They attach to the Velcro and clip-in panels on these packs and slings, so you can add pockets for a phone, cards, chargers, or small kit without changing bags. Sold separately.
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.
