I share my opinion because I had trouble having feedback on these lags, especially on the size to choose. I comfort you the satisfaction of my purchase.
The leather is of very good quality, they are very flexible and the adjustment system by steel and non -crochet loops is a big advantage. This is the reason why I absolutely wanted this loop system because from experience, hook systems wear out very quickly and the leather relaxes, which no longer allows good hooks.
Attention ! These calibers cut very large therefore distrust with the dressing size, fortunately I took the size below in full.
For information: I measure 1m75. I bought them in full size (70cm) and it is perfect for my length on my dressing saddle. (Isabell Werth).
For even more precision, here are the exact measures of these:
Boucles positioned in the shortest hole: 54.5 cm in length (from the passage of the knife to the swaying of Etrier)
Books positioned at the last hole therefore at the longest: 64.5.
There are between these two 9 -hole adjustment measures.
Personally, with my 1m75, I rules them 59cm in length.
My comment will help future buyers who have a doubt about the choice of length.

Far too tall for me, very disappointed on this point, otherwise the quality is top

Good quality calipers, I took them size dressage (I am 173cm) and bah I will have to redo holes because it is far too large! Despite my research, this size was to correspond to my activity but unfortunately not at all. A little disappointed but it is reparable.

Very good product, soft and good quality leather, to see its duration over time.

Top Etrivière, I took a size 60cm Top to go from cross to dressage, I would almost miss a hole for cross (I am 1m67)
Be careful if you climb the curls pinch the inside of the calves without boots
