When going out to eat I'm asked what my favorite dish is. Usual answer from me is "food". I eat and cook everything from Indian, Thai, Mexican, Cajun, Soul, African and all parts far and wide. So to narrow a kilt down would be like narrowing a dish down to what happens to be my taste at the time. So here is my two cents on favorite kilt or kilts and why.

Bonnie Heather Greene tank in German Heritage 16oz wool ===== dress, weddings and special occasions
Hecktor Russell PV Modern MacKenzie ==== 1st kilt that I bought in Scotland
Stillwater Economy Wool Black Watch====== Daily comfort for my walks to work, groceries etc.
My homemade quickdry nylon running kilt === designed like a traditional kilt yet lightweight material for running.
ElKommando Kilt by Mountain Hardwear ====== great hiking kilt

I cant exclude any of my other PV or wool kilts as they all have a purpose such as pubs, movies, camping, hiking and daily wear but the above I would say are my favorites for their specific purpose.
