# **Kylebooker LIFE FLEX – Hareline Fly Tying Spandex Rubber Leg & Body Material in 20+ Colors: Is It Worth the Money?**
As an avid fly fisherman, I’m always on the lookout for high-quality tying materials that can enhance my flies’ durability and lifelike movement. Recently, I came across **Kylebooker LIFE FLEX by Hareline**, a spandex rubber leg and body material available in **20+ vibrant colors**. Naturally, I was intrigued—but does it live up to the hype? In this review, I’ll break down its **performance, versatility, and overall value** to help fellow anglers decide if it’s worth adding to their fly-tying arsenal.
## **What Is LIFE FLEX?**
**LIFE FLEX** is a stretchable, synthetic rubber material designed for tying **legs, bodies, and other appendages** on flies. Unlike traditional rubber legs, this product is made from **spandex-based fibers**, offering superior flexibility and a more natural movement in the water. The **20+ color options** allow tiers to match various insect species, making it a versatile choice for nymphs, streamers, and bass bugs.
## **Performance & Durability**
One of the biggest selling points of LIFE FLEX is its **realistic action** underwater. When tied onto patterns like **woolly buggers, stonefly nymphs, or hoppers**, the legs undulate naturally, mimicking live prey. I tested it on a **bass popper**, and the legs pulsed enticingly with each strip—something that rigid rubber legs often fail to achieve.
Durability-wise, **LIFE FLEX holds up well against toothy fish**. Unlike some rubber materials that fray or snap after a few strikes, this spandex blend maintains its integrity even after multiple catches. It’s also **UV-resistant**, meaning colors won’t fade quickly under prolonged sun exposure.
## **Versatility in Fly Tying**
Beyond legs, LIFE FLEX can be used for:
– **Bodies:** Stretched thin, it creates a segmented effect on nymphs and larvae.
– **Antennae:** Perfect for **cricket and hopper patterns**.
– **Extended tails:** Adds extra movement to **streamers and baitfish imitations**.
The **wide color selection** (including natural hues like **olive, brown, and black**, as well as bright **chartreuse and pink**) makes it easy to match local forage. I particularly like the **pearl and UV-reactive options** for attracting fish in murky water.
## **Price & Value**
At **around $6–$8 per pack** (depending on the retailer), LIFE FLEX is **slightly more expensive** than standard rubber legs but offers **better performance and longevity**. Considering that one pack can tie **dozens of flies**, the **cost per fly is minimal**. For serious fly tiers, the investment is justified by the **enhanced action and durability**.
## **Final Verdict: Is It Worth It?**
**Yes!** If you’re looking for **high-quality, realistic movement** in your flies, **Kylebooker LIFE FLEX is an excellent choice**. While it’s pricier than basic rubber legs, the **enhanced action, durability, and color variety** make it a **great value** for dedicated anglers. Whether you’re tying **bass bugs, trout streamers, or saltwater flies**, this material will elevate your patterns.
**Rating: 4.8/5** (Highly recommended for serious fly tiers!)
