The American Heritage tartan is a fashion tartan, designed and registered by the owner of USA Kilts, William C Roeger III.
The USA Kilts Casual is a very well made 4-yard kilt and the fabric is a non-piling PV from a British mill. Instead of bucles and straps it has a Velcro closure. That means that it goes into the washing machine without problems (30 C / 86 F or lower). The casual kilt can, according to the USA Kilts website be worn either at "true waist" ie. at your navel like a traditional kilt, or at "jeans waist".
I have bought my USA Kilt second hand. The seller's wife would not let him wear it. She would not even allow the kilt to be inside their home! Thus, he had to get rid of it (or his wife). When ordering it he had used the option of having belt loops for men's ordinary 1.5" wide belts, rather than for wider, regular kilt belts. It is fine with me. Whenever I prefer wearing a kilt belt, I simply don't use the belt loops (which in fact are not for the belt but for the sporran strap).
I also know that he had intended to wear it at jeans waist and therefore ordered it 20" short. On me, even at jeans waist, it is to the short side. Quite a few, no doubt, will say it is too short, and worn at true waist it certainly is, at least from a traditional point of view.
Nevertheless, I really like my USA Kilts Casual and do wear it a lot, low or high, with different types of belt, with and without a sporran, mostly without, with kilt hose up to the knees or scrunched down, or with just ordinary knee high socks, as well as with 'invisible' socks or no socks. At low temperatures, I have even worn it with leggings or tights around my knees. Well, men are already wearing them together with running shorts etc., so why not with a casual kilt?
On my feet I on most days will wear sneakers, but also leather shoes, and different kinds of boots.
Depending on temperature, t-shirts, and polo shirts, tucked in or untucked, as well as short wind breakers (type bomber jacket or anorak).
The USA Kilts Casual having no metal parts also means that it won't set any alarms at airport's security, meaning I have several times been wearing it on board airplanes and when checking in at airports. Certainly, a high quality, most versatile kilt and accordingly highly to recommend.
To a European like me the only drawback with this kilt is that it comes from the US, resulting in high freight cost, customs, fees, and VAT on top. But even this should not one day prevent me to order another USA Kilts Casual!
