I tend to agree wholeheartedly with Devil39 on the utility and acceptability of good-quality after-market kit. Perhaps our shared time with 3 PPCLI on operations has something to do with our somewhat "non-conformist" but emminently practical approach....
CFL is correct. I know for a fact that limited stocks of the DZ "Recce Smock" have been purchased by more than one "Western Battalion" to kit out their Recce Platoons. The smocks were purchased using unit and/or sub-unit generated NPF. Those "enlightened" units have recognized the Recce Smock as the superb piece of kit that it is, and have authorized them for field wear. I saw several Western-based sniper teams sporting the DZ Recce Smock during this year's CISC.
At the end of the day, the Recce Smock is no different than a Stealth Suit or a "better-than-issued" pair of boots, gloves, etc. It is constructed of genuine mil-spec CADPAT material and cannot be mistaken for anything other than Canadian. My own experience has been that most folks (of all ranks) don't give it a second glance in the field. And if they do, the comments are universally postive. Soldiers know a solid, practical piece of kit when they see one. The most frequently asked question by those "not in the know" is when they can expect to receive their issued smock - at which point I must regretfully shatter their expectations of truly practical and functional issued clothing.
I have never received a negative comment from my superiors (Cmdt Tac Sch and Comd CTC) regarding my use of the DZ smock in the field. Instead, I have fielded many questions from soldiers of all ranks who are manifestly dissatisfied with the lacklustre performance of the issued combat jacket. Even those who did not previously understand the inherent logic of the smock concept (versus a heavy, hot, non-breathing jacket) immediately "get it" when the idea of a lightweight 3-seasons outer shell is explained to them.
At the end of the day, individual and unit acceptance of practical and functional after-market clothing and equipment is largely a cultural matter. It all depends on your military military background. There are those (even today) who honestly believe that "if it isn't issued, it isn't acceptable". And then there are the growing number of "cowboys" who take a more practical view and apply the best tool for any given job (within reason, of course). There are arguments for both approaches, but at this point in my military career I am not about to be swayed by the "uniformity at all costs" crowd. Uniformity of dress in garrison is one thing. However individual performance and practicality in the field trumps "parade-square" uniformity every single time.
