Straight from Schneiders catalog... VTEK *V-Free
Raised, shaped area over the withers. Contoured over the back and hindquarters..
Image shows higher than normal cut, well above the wither bone. Well above where the mane starts. EURO
No back seam, straight line over the withers and back. Contoured over the hindquarters.
Image shows blanket would cover entire wither to neck juncture. Fitted V-Free
Raised, shaped wither up to the start of the mane. Contoured over the back and hindquarters.
Image...exactly what it says... think a contour saddle pad fit. Cutback
Cutback at withers. Contoured over the back and hindquarters.
Image... picture shows the blanket NOT covering any of the wither, leaving it exposed.
OK.... so my take on it for what it is worth...
I would NOT do a cutback. I've seen them get so far behind the wither they get caught, leave nasty rubs where the fleece is constantly chafing the back area.
I would NOT do a VTek V-Free either. To close a neck opening unless that is what you desire.
I would Do the Fitted-V. raised wither and contoured cut over the back and butt.
I would consider the Euro...a higher cut over the Fitted-V but it doesn't "hug" and fit as close to the body... to me that can lead to blanket slip.
Both the Euro and Fitted V-Free start at just above or at the "mane starts here" location.
Now as for the weight of warmth material, sizing, colors, options.... you are all on your own.
Hopes this helps.
I received a "Blanket Catalog" in the mail from Schneiders that I took this information from.
I could not find it on their website, I looked.
This guide is very extensive in the information and goes into great detail on every cut.
Call or order a blanket catalog... if you called customer service they could probably scan and send you this page of in-depth information...
