I bought this cap for my wife. This is our family's second Kromer, both seem to run small despite following the measuring instructions on the site. Wife came up in between sizes so we ordered the next size up; still just a bit too small. We returned for one more size larger and she loves it. I had a similar experience with my Original but after getting it right I recently bought another cap and vest. With now three Kromer caps in the stables plus some clothing and accessories we're ready for whatever ole man winter can throw at us.
