These are my favorite side reins. My mare naturally wants to stretch down into contact, so I didnt use these on her, but my gelding wasnt so easy. I chose these side reins for him because they're fairly forgiving, and if adjusted properly, reward the horse when he uses his front end properly. I know a lot of people dont like sidereins, but I think like anything, if they're used properly in moderation, they're a valuable tool. I used these to introduce the idea of light contact to him on the lunge for a few sessions, and havent needed themsince.

Pros: have some 'give' to them

Cons: inexperienced people can still put them on too tight

My horse likes the elastic side reins much more than the donut ones..The elastic stays pretty constant once he accepts the pressure but the donuts swing around and scare him..the elastic ones encourage the horse to stretch and hopefully mimmik the giving nature of the riders hands. :)

Pros: great for encouraging the horse to stretch

Cons: can cause the horse to pull a little

Elastic side reins are definitly the way to go, they give and allow a more rider like feel. They are great for lungeing and long lining.

Pros: adjsutable, easy to use

Cons: n/a

These are a bit shorter than the leather and elastic ones you can get from dover, but they work well for horses with shorter necks.

Pros: Good Elastic

Cons: Bit short

They are easy to use and very beneficial. If your horse doesn't bend well this will help teach them without being too intrusive.

Pros: useful!

Cons: not too cheap
