PiggyBack Pack – 12L/15L Modular Hydration & Sustainment Pack
The PiggyBack Pack is a modular hydration and sustainment pack offered in two sizes: 12 liters (750 cu. in.) with a half clamshell opening, or 15 liters (900 cu. in.) with a full clamshell opening. Both measure 15" × 10" and lay 5 to 6 inches deep, and an interior divider sleeve holds a 3L (100 oz.) bladder up to 15" tall and 10" wide, or a radio. It mounts to a FullTang chest rig shoulder harness through the patent-pending Universal H-Harness Receiving Sleeve to run as a standalone day pack, or attaches to larger packs and plate carriers by MOLLE or straps. A full-length zippered admin pocket with a laser-cut MOLLE grid covers the front, and a removable 1/4" foam insert adds structure. Built from DWR/TPU-coated 500D nylon and 1500D laminate, 14 to 16 oz, with a choice of water-repellent YKK® AquaGuard® or standard reverse coil zippers. Sold in base configuration: shoulder harness, pads, straps, and pouches are sold separately. Hand-made in Tennessee by FullTang Tactical.

AMERICAN-MADE MODULAR GEAR
Founded by JT after a corporate career, named for an Appalachian boyhood obsession with full-tang blades. Built in the backwoods of Tennessee.
FullTang Tactical, LLC is a small, family-owned business founded by JT — who left a successful business executive career to fill a gear void he'd personally hit: the modular tactical and outdoor gear that met his standards didn't exist. The brand name comes from his boyhood obsession with full-tang knives and hatchets growing up across the Appalachian Mountains, Maine pine forests, and Minnesota boundary waters. Every product is manufactured in their facility in the backwoods mountains of Tennessee. Their flagship Minuteman™ Pack V2 was inspired by JT's family military heritage — father (82nd Airborne Paratrooper/Ranger) and grandfather (Iwo Jima survivor).

Answers, straight up.
Product-specific questions on the left. Shopping with SRO on the right. Both open-ended — hit us if we missed one.
Are shoulder straps included?
No. The PiggyBack ships in base configuration. It mounts to a FullTang chest rig shoulder harness, or to a larger pack or plate carrier. Harness, pads, and straps are 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.
