Went just under the sizing guide for this one, and it fits perfect. Good quality leather, feels great too

Really loving the armbands now that the right size came! Can be used around the biceps, as a neck collar! I originally ordered based on the required circumference, but realized the armband is slightly more loose as the pin the buckle adds an extra 1.5-2cms, and I prefer a tighter fit. The middle eye hole is the selected size (35cm) circumference measured from the pin to the eyehole. Contacted SAX by live chat (very helpful), and Sax was more than happy to resend the size down. Look forward to future purchases ;)

Great for your biceps...or tying your MAN to a chair, wrists, ankles, calves!!! The longest 45cm is great for this!
