Flexible Filly Front Closed Equine Splint Boots

Wrap your horse in comfort with this lightweight breathable non-slip protective horse boot. These horse splint boots are great for horses and even better for owners. The low profile fit is only outdone by the ease of care for horse owners.

Why is this horse splint boot lined with ThinLine?

Our trademark open cell technology delivers impact protection in a wafer-thin breathable foam, perfect for a horse splint boot. ThinLine doesn’t compress. Pressure points; created from tendons, bones, splints, or wind puffs, are gently shaped into the ThinLine memory which rebounds once it is off the horse. Additionally, an anti-microbial agent is infused into ThinLine allowing use on multiple horses. ThinLine foam does not absorb water or collect dirt which means boots stay in place and are easy to maintain.

Pro Mesh Exterior Construction

Pro Mesh is used for the protective outer layer of our closed front splint horse boots. Pro Mesh material acts like ‘flexible horse armor’ offering the ultimate combination of breathability with impact and abrasion protection as well as support and durability. Additionally, Pro Mesh is engineered in a way that reduces the amount of stitching and glue required during boot assembly.

What is Pro Mesh Engineered Material?

Pro Mesh material is RoHS and REACH compliant. Directly injected into a strong but breathable fabric mesh the materials bond and become ONE and will not separate. No toxic glues are used. Pro Mesh is extremely tough, strong, and conforms to shape allowing it to outperform fabric or leather boots.

Cools and Protects

Pro Mesh G3 was designed by SinoBlue specifically for equestrian boots. It uses a honeycomb hex pattern that reduces weight plus offers an optimum mix of protection, airflow, strength, and flexibility. Designed to keep out grit and sand it helps guard against rubbing. Water-resistant, strong and protective, this closed front splint horse boot is designed to deliver support with flexibility, thereby maximizing joint movement.

Strong & Durable

Our technology focuses on equestrian leg protection needs. By combining materials using state-of-the-art tooling design and injection techniques synergy was attained between these materials.

ThinLine Pro-Mesh is the most effective and durable horse boot on the market. Your Flexible Filly Boots come with a one year 100% replacement product warranty. We recommend Flexible Filly boots for both riding and turnout.

Flexible, the name itself describes our boot; Flexible Filly Closed Front Splint Boots for Horses.

Lightweight: Each boot weighs only 7 ounces, (.2 gram).

Sizing:

Medium and Large. Most horses will wear a medium for front boots and a large for hind boots. Please refer to our sizing chart below if you are interested in a full set.

Available colors, White with Black ThinLine or Black with Dark Brown ThinLine. Sold in pairs, one for the left, one for the right. They are called Closed Front because they are, well, closed in the front. This does not mean they are only for front legs.

surprised!
I actually didn't realize I had ordered "time released" version. I thought these were just normal melatonin. But now that I've tried these, I love them so much better than the regular version! Helps me sleep better through the night. No taste, love this brand of Source Naturals.

The only one I'll use!
As the title says, this is the brand to get!! It's fast-acting, doesn't give me weird dreams like some do, and I never wake up feeling groggy.

Works wonders
I've been buying these for well over a year now as Subscribe and Save. I work 12 hour overnights as a nurse. My sleep schedule normally gets messed up. I would have no problem falling asleep but would wake up only a few hours later which is not good when you have work again that night. We buy these on Amazon due to the great price and the fact that they are extended release which helps keep me asleep longer. When I take 1 or 2 of them, I am able to sleep about 7-8 hours which is great. I take this both when I sleep during the day and sleep during the night. It helps me sleep no matter when and I am able to adjust my sleep schedule often. I have recommended them to many.

Works quite well, dose still a bit high for me
Used to take the Natrol 5mg slow release, now that I can compare these 2, I love this more. It doesn't make me feel too edgy, it's quite relaxing actually. I still have to halve the dose as the full dose makes me groggy the next day. Where the Natrol gave me very vivid, but not unpleasant dreams, these don't make me dream as vividly. It does take a bit longer to get me to sleep, but once asleep, your asleep. Highly recommend, once I finish this bottle, I'd get the 2mg tr next time, as a lower dose works better for me.
