Overview
Key Features
💪 FLEXIBLE & STRONG- Each cord in our pack is 8mm thick, with a maximum break strength of 100 lbs, and can expand as much as 50% its original length. It’s the perfect adjustable tie-down for bulky cargo.
💪 QUICK STORAGE – When not in use, bungee cords have the uncanny ability to get all over the place. Not these ones! They come in a black, polyester sack so they stay intact, right where you need them.
💪 NO MORE TANGLES - As we all know, cords love to form knots when no one’s looking. Our bungees come with a Magma-branded Velcro strap to keep them from tangling even when the storage bag is jostled.
💪 VERSATILE HOOKS – These ties have hooks on both ends, making them easier to lock or clasp around a roof rack. This double-ended feature makes mounting packages around a motorbike easier, too.
💪 DOUBLE THE STRENGTH- Our straps are double braided for a stronger but elastic construction. The core is made of latex and rubber, which are then wrapped in polypropylene yarn.

Pros & Cons
👍 Pros
- 100 lb rated break strength per cord with double-braided latex and polypropylene construction handles heavy cargo loads without the elastic fatigue that single-braid cords show after repeated heavy use.
- Individual Velcro straps keep each of the 12 cords bundled separately, solving the tangle problem that makes most multi-pack bungee sets unworkable after the first use.
- 50% stretch extension from a 2.5ft resting length gives meaningful adjustment range for securing loads of varying heights and shapes without swapping cord lengths.
- Polyester storage sack consolidates all 12 cords in a single portable unit — practical for keeping in a vehicle, cargo bag, or garage without scattering.
- Double-ended hooks provide attachment flexibility for roof racks, motorbike luggage frames, and cargo rings without requiring separate hardware.
👎 Cons
- Hook width is fixed — the clasps don't adjust to accommodate unusually narrow or wide anchor points, which limits compatibility with non-standard rack geometries.
- At 8mm diameter, these are mid-weight cords: suitable for heavy cargo, but overkill for lightweight tasks where thinner, lighter cords would be less cumbersome to attach and remove.
- Metal hooks are not specified as stainless or coated for corrosion resistance — in sustained wet or saltwater environments, hook longevity is a real concern that the product doesn't address.
- A pack of 12 identical 2.5ft cords offers no length variety — users who regularly need both short and long tie-downs will want a mixed-length kit alongside this one.
Frequently Asked Questions
How long is each cord, and how much stretch do they actually provide?
Each cord is 2.5 feet long at rest and can extend up to 50% — reaching approximately 3.75 feet under tension. That stretch range handles most standard cargo tie-down tasks: securing gear to a roof rack, strapping luggage to a bike rack, or holding a tarp over a truck bed load.
What's the difference between double-braided and single-braided construction, and why does it matter here?
Double-braided means the latex and rubber core is wrapped in two layers of polypropylene yarn rather than one. The practical result is higher break strength — rated at 100 lbs per cord — and better resistance to abrasion and UV degradation over time. Single-braid alternatives at the same diameter tend to fray and weaken at the hooks first; the outer braid on these absorbs more of that wear.
Do the hooks stay secure on roof racks and cargo rails without slipping?
The double-ended hooks are designed to clasp around standard rack crossbars and cargo rails. For smooth round bars, the hook geometry works well. On irregularly shaped or very wide anchor points, fit can vary — the hooks aren't adjustable in width. Inspect the attachment point before loading to confirm a secure clasp.
How do the Velcro straps actually prevent tangling between cords in the storage bag?
Each cord has a Velcro strap that bundles it into a compact loop before it goes into the storage bag. This prevents the hooks from catching each other and the elastics from intertwining — the problem that makes most bungee packs a frustrating mess within two uses. Individual bundling is the key: the cords stay separate, so you pull out one at a time cleanly.
Are these cords suitable for use in wet or marine environments?
The polypropylene outer braid and rubber/latex core hold up to moisture exposure better than uncoated elastic cords. For occasional wet-weather use or marine deck applications, they're adequate. For permanent saltwater exposure, inspect the metal hooks for corrosion regularly — the hooks are the most likely failure point in sustained marine conditions.
