Bungee vs. Biothane E-collar Strap
Flex Collars and the Standard e-collar strap
Choosing the right strap for your e-collar can make a massive difference to comfort, contact quality, and training success. Two materials dominate the market: Biothane (the stiff, waterproof-coated webbing most collars come with) and Bungee (the flexible, elastic-style strap, like Flex Collars).
So which one is actually better?
Quick Comparison between Bungee and Biothane Strap
1. Comfort
Biothane is stiff and can feel like a hard belt around the dog’s neck. Bungee straps have built-in stretch, so they move naturally with the dog when they swallow, turn their head, or run. This dramatically reduces pressure sores and collar rubbing — especially important for long training sessions or high-drive working dogs.
2. Reliability & Contact Quality
This is where bungee wins. A biothane strap can loosen, rotate, or create gaps when the dog moves — especially dogs with long or thick coats.
“Thanks again. I’ve been using Dogtra’s slick collar that comes with the 1900X and no matter how tight I make it, my husky’s long hair and him constantly shaking his head makes it slip down around his throat. I’m so excited to try this product and hopefully it stays put.”
Flex Collars bungee straps solve this problem. They don’t slide, don’t flip, and don’t twist on the dog’s neck. The elastic design maintains constant, gentle contact, allowing you to use much lower stimulation levels while still getting reliable communication.

3. Ease of Adjustment
Biothane straps only let you adjust from one pre-punched hole to the next, which sit 1-1.5cm from each other. Flex Collars bungee straps can be micro-adjusted up to 1 mm, giving you a perfect custom fit for your dog.
4. Real-World Performance
Prey-driven and hunting dogs: Bungee is noticeably better because the dog is constantly moving.
Livestock aversion training: The consistent contact means faster, cleaner learning at lower levels.
Working/ military dogs: Bungee gives comfort when serving duties
Everyday pet dogs: Many owners report their dog stops noticing the collar is even there when using a bungee strap.
5. Durability, Weight & Cleaning
Biothane is made of a very strong material. It is almost indestructible and wipes clean easily. High-quality tactical bungee (like Flex Collars) is made with UV-resistant, weather-proof elastic and Cobra Quick-Release buckles. It is ultra-light and will easily last 2–3 years of daily use.
Why More Professional Trainers Are Switching to Bungee
Trainers who work with serious behavioural issues or working dogs want maximum reliability with minimum stimulation. The elastic nature of a well-made bungee strap gives exactly that.
That’s why Flex Collars are now stocked by DogTra UK and recommended by multiple Professional Dog Trainers.

When Biothane Might Still Be Better
Extremely wet or muddy environments (biothane wipes clean instantly)
Budget-conscious owners
For the vast majority of serious e-collar users (90%+), a quality bungee strap is the better long-term choice.
