The walk is happening anyway.
Put weight on it.

It's one adjustable size worn over your clothes. There's no cut to get wrong, and the side buckles pull the waist band in to your frame. The weight rides at your waist, not on your chest. Starts at four pounds. If it doesn't sit right, send it back inside 30 days. Light ships back free.

Cinch the side buckles before you walk and the vest moves with you, not against you. The straps are padded where they cross your shoulders. Start at 4 lb, walk in it for a week, then add. A vest that's too heavy on day one ends up in the closet.

For walking, most people start well under 10 lb — day one should feel like a heavy sweater, not a workout. If you already carry a loaded pack on hikes or do stairs regularly, start with Core at 20.

Send it back. You have 30 days from delivery, for any reason, for a refund of the purchase price. Light ships back free. On Core and Heavy the return label cost is deducted unless the item is defective. We built the walk test because the closet is where most vests end up — we'd rather take it back than have you look at it. Details on the shipping & returns page.

From a US warehouse. Orders are processed in 1–2 business days and delivered in 2–3 business days after that — plan on 3–5 business days door to door. Shipping to the contiguous US is free through Oct 31 (normally a $4.90 flat rate); $19.90 to the other countries we ship to. We can't ship to Hawaii, Alaska, US territories, APO/FPO or PO boxes.

Every single one. Light ships with six 1 lb pouches, Core with six 2 lb packs, Heavy with eight. Every pack for your model is included in the price. You open the box and you have the full range.

There's no HEFT between 10 and 20. Light tops out at 10; Core starts at 20 with the packs out. If 10 already feels easy on your walks, Core is the next real step.

The packs are sealed iron weights in double-stitched pockets. Neoprene can carry a faint factory smell for a day out of the bag — air it out.

Wipe it. Take the pouches out, wipe the neoprene with a damp cloth and mild soap, hang to dry. Do not machine-wash and do not submerge the pouches.

Train in it. Walk in it. Hike in it. It is built around the daily walk — weight low at the waist, nothing on your chest, off in five seconds — and that same build works for stairs, push-ups, squats and bodyweight days. What it is not is a plate carrier: 40 lb is the ceiling on Heavy, so if you want 60 lb for CrossFit, buy a plate carrier.

Weighted vests are exercise equipment. If you have back, joint, heart or blood-pressure conditions, or are pregnant, talk to your doctor first. Start light and add weight slowly — that is exactly what the pouches are for.

We don't make health claims. HEFT adds four to ten pounds to the walk you already take, so the same route asks more of your legs, hips, and heart. What that means for your health is a question for your doctor.
