Frequently Asked Questions

What is...

Brahma Webb™ made by Weaver Leather, is a great choice for synthetic harness or tack. The web is very durable, tough and wears excellent.

Brahma Web™ strapping has a thin interior webbing impregnated with synthetic material which looks and feels very much like leather.

Most Brahma Webb™ is matte finish and grained to resemble leather. A great alternative to leather, Brahma Webb™ offers easy care, weather resistance and durability.

Brahma Webb™ is not affected by weather, does not absorb water, does not stretch, maintains its shape, and is easily cleaned with water or a damp cloth. It is extremely durable! 

Many of our horse sizes harnesses are made from Brahma Webb™ and most of our traces. Our colored harnesses such as the MaraFUN and the colored parts of the ComfyFit and Trail Harness are made using Brahma Webb™ material called soft strap.

Some of our first Brahma Web™ harness made in 1993 and 1994 is still in daily use and shows no sign of wearing out!

BioThane® is a synthetic product made in the USA.

BioThane® is the brand name of all coated webbing products made by BioThane Coated Webbing Corp. It’s basically a polyester webbing with a TPU or PVC coating that makes it more durable, waterproof, easy to clean and weldable.

ComfyFit harness, the Pleasure harness and all of our driving lines are made using the Biothane® material.

We only have BioThane® in black and brown.

Please go to the Size Chart Page to watch a video showing how to measure.
We require measurements for EVERY HARNESS PURCHASE.

How do I measure for...

  1. Measure from the corner of the horse’s mouth on one side, over the poll (behind the ears) to the corner of the horse’s mouth on the other side. This is called the poll measurement.
  2. Measure from temple to temple across the horse’s brow. This is called the browband measurement.
  3. Measure all the way around the horse’s nose approximately 2 fingers below the tear bones (located about midway down the horse’s face). This is the location for a cavason. The measurement is called the Noseband measurement.  Bridle measurements for various sizes are included with the products.

If you have a bit which fits your horse, measure the mouthpiece from inside the cheek on one side to the inside of the cheek on the other.

If you need to start from scratch, use a smooth straight stick, ruler or dowel and place it in the horse’s mouth as if it were a bit. Then mark the stick with a marker or pen at the outside of the lip. Once you remove the stick from the mouth, simply measure between your marks with a measuring tape or ruler.

It does not matter how well a horse collar is made, if it is not properly fitted to the horse it is sure to hurt him. It is therefore necessary to use the greatest care in selecting the proper shape and size collar for your animal.

To measure your animal for a collar, use a collar measure as shown, or make one from carpenter’s squares or cut one from cardboard. Place this caliper as shown. The collar measurement requires a straight line thru the center of the horses neck. 

To measure a Collar, not the animal, place a ruler against the collar cap and measure to the inside brim of the throat as illustrated right. It is easily done if you lay the collar on a flat surface and measure with a tape measure inside the rim from top to bottom.  

For size of draft, measure around the collar at the widest part, of one side near the bottom.   
When fitting a horse with a collar there should not be any more space between the horse’s neck and the throat of the collar than will allow your four fingers, when laid flat on the inside of the throat of the collar, to pass freely.

If care is taken in fitting the collar and adjusting the hames so the hame tug comes over the center of the draft, you will have eliminated all trouble with sore necks and shoulders and the horse will work with ease and comfort. More collared horses are ruined by collars which are fitted too large than from any other cause.

The size of the hames is dependent on the size of the collar. Buggy hames are generally the same size as the collar and Work Hames (Farm Hames) are adjustable and vary based on the size of the collar.  Farm hames can generally accommodate more than one size  collar.

Measuring for a harness is not difficult, but it is essential to getting a correct fit. See the following key and illustration below.

A. From corner of mouth, over poll, to other corner of mouth.
B. Length around nose, taken about two fingers width below the prominent cheek bone.
C. Length of browband – temple to temple.
D. Length of horse measured just on the side.  Not center of chest to center of tail.
E. Height of horse from lowest hair on mane to the ground.
F. Girth – measured at the heart girth as shown.
G. Length of back from position of harness saddle to base of tail. Line should be straight, not conforming to horse’s body.
H. Point of shoulder to point of shoulder on the other side.
I.  Point of hip to the point of hip on the other side.

We require measurements for EVERY HARNESS PURCHASE.

Our harnesses are guaranteed to fit. This means we need you to measure twice and order once. Or even better, measure three times and order once! We have a How To Measure Chart you can take to your horse to write down the measurements you get. We ask that you be as accurate as you can, without over thinking it or stressing about it. Mindy Schroder will be contacting you either through email or phone after you place your harness order, to confirm the measurements you gave. Here is a guide on to how to measure.

What if?...

Oh, dear! We’re very sorry.  If we have sent an incorrect item we will pay for both the return shipping costs, and ship you the correct item as soon as possible. Life does get in the way sometimes and we apologize for the hassle.

If you inadvertently ordered the wrong item here on our website, just give us a call and we’ll sort it out together.  It is fine for you to be human too.  We generally do not pay return shipping in such cases.

We try our best to make sure each item is exactly what you’d like. Special order items which were made to your specifications are not returnable.  As the saying goes, “Measure twice, cut once…”

However, if you’ve measured twice and still somehow managed to receive an item that isn’t quite right, we’ll work with you to make sure you’re happy. Just give us a call.

We accept returns of like new in-stock merchandise within 30 days of purchase unless other arrangements have been made.  Like new condition means you can try the product on and be sure it fits and  you are happy with it.  If for some reason you need to return it or exchange it for a different size, etc. it is important for you to be sure it is clean before you return it!  Also, be sure that parts are put together as they were when you received the item.  Returned parts that are dirty have to be sold as used parts; you will be charged a restocking fee in such cases.

We are generally glad to trade sizes; your job is to return clean parts to us for exchange.  Thanks.

There are two exceptions: you’ve specially ordered tack with brass hardware or colored strapping.  These items are not returnable.  We will try always to let you know brass is not returnable but even if you don’t remember that it is not returnable, we will remember!  Colored strap goods are not returnable as well.  You may have wished for a purple kick strap but it will not resell.

Please see the following question about returning custom-ordered items.

Special order items are not returnable, this includes brass hardware and colored straps. Whether that is halters, bridles, harness or driving lines they are not returnable!!

We simply can’t take these items back as they are custom. Please be sure to reach out if you are unsure about what it is you need. If you order the wrong thing and then don’t like it when you get it, we are truly sorry but will no longer take these orders back.

While we always encourage our customers to contact us via phone or email for any questions you may have, we also encourage you to please place your orders through our website! We get many requests to place orders through the phone or email, however, placing your order through the website will help things run much more smoothly on our end for you! When you wait for us to make you an invoice for you, it will take much longer than if ordering the product yourself through our website, and is more likely to be done incorrectly as the process for us to make invoices is more difficult than simply ordering straight from the website

If you are worried about your order in any way, you can put a note in the note box to have someone call you to verify your info/order before it gets sent to the harness maker, collar maker, blacksmith or evener shop. The notes sections will be found AFTER you start checkout, below the billing and shipping information. You will see a box that says “Order Notes (optional):” (see above). This is where you will put your measurements and any other information we need to know or that you feel is important.
