Wonderful strap! I bought this for my Muhle Glashutte Teutonia Sport 2. The kevlar material is well made and appears rugged and stylish IMO. The underside padding material is very soft and comfortable. I am not sure what it is composed of. The strap is water resistant and easy to clean. My watch uses screws instead of spring bars so I had to take it to a watch repair shop to have the stock worn out strap removed. Nevertheless, it was quite easy to place the screws through the mounting holes in the strap.
Overall very happy with the strap. Holbens service was very good A+.
Holbens is a real pleasure to deal with. The whole team is fantastic! Cust service is top notch!
Now the band. Had it on for about a week, molded perfectly, light, comfortable, tough, and great looking. Has been warm and muggy, and no problems with comfort. Stitching is great. The lorica liner is comfortable, and the strap holes do not pull out of shape. Have about 7.25" wrist, for reference.
