First I'd go with the WPG 22ozer. I got a MacKenzie two years ago and it works great with the proper layering underneath (I wear either polypro or Smartwool boxers) and you'll stay very toasty. Second I would opt for a SWK Heavyweight. The SWK gives you more seasons/times to wear your new kilt whereas the WPG has temperature limitations. But go for the WPG and you'll not be disappointed. I call mine "The Beast" and it works great during the dry cold winters up here on the Western Slope of the Rockies. I can wear "The Beast" from 60'sF to sub zero F. But like I said, proper layering, including proper footwear and sock/hose combos is very important. Either way you'll end up with a fine kilt.
