I assume this price is for 1 each? There are BDU belts with parachute-grade buckles, airport accepted, that come in widths from 1.5 up to 2.25 and selected lengths for various size folks and a multitude of colors for about $20. Being an engineer and partial to high grade metals Titanium buckles are my choice although there are issues with Titanium most people are not even aware of, and I won't go into the details why in this venue.

Sailing40Are you referring to the possible health issues with substances like titanium dioxide, which js frequently added to the things you eat to make it white/sparkle?

Sailing40As an engineer myself I'd love to know the issues you speak of. Not claiming there aren't any, just wondering what you are referring to explicitly. Personally I believe Ti is overrated for the most part, as it's strength to weight ratio is roughly equal to a high grade SS or quality Al. alloy. It definitely has its uses (such as in a high heat environment or when you need more sectional density for an application that aluminum isn't well suited), but it isn't the end-all be-all that some proport it to be. Carbon fibre (henceforth referred to as CF), as well as a handful of other composite materials on the other hand, pretty much is the standard by which all others are judged from a strength to weight standpoint, though like anything else there are still disadvantages (such as sunlight resistance and greater sectional density, which isn't ideal in some applications).
I do wonder why everyone is so excited about the Ti version and not the CF variant. I have a Ti belt myself and it's well suited to the task (I would not want to rappel on a CF buckle), but personally I find the CF version to have better aesthetics as well as more practical (it's lighter and less likely, I hope, to get noticed at the TSA checkpoint). Am I missing something that potentially makes the Ti version a better choice or is it simply differing opinions regarding aesthetics?

M.a.vI began to explain both my preference and my concerns based on experience in the aircraft design and much later as a Senior Research Engineer at a National Laboratory where our concentration focused on Nuclear work. Most of what I would have intended to disclose came from research where “Off-Gassing”… While working at a major aircraft company, one of my assignments was to redesign the portside engine pylon as a result of relocating the air-condition equipment within the tail section of the just below the vertical stabilizer. Load testing, tensile and compression test including the all-important thermal test were conducted. I found the redundancy of the thermal loading somewhat confusing until an older engineer who had been there long before I was born tell me that it wasn’t ‘how much heat’ would lead to deformation thereby creating a condition where the engine would just fall off. I was overlooking something I had never considered as a young engineer; it’s much closer relationship to the new air-conditioning equipment, specifically the ducting into the cabin… I apologize for not revealing more, but I’d be treading in an area that could violate my clearance, although being retired, I’m still held to my clearance conditions. I believe you could easily see where I was going with this, and not completing this, a layperson would view me as a nut. Oh well.

Sailing40It's pretty awesome how much engineering is going on here right now! Thanks @M.a.v and @Sailing40 for that. My background and degree is Aerospace Engineering as well. I've used carbon fiber much more than titanium in that area though. When it comes to something like this, both materials are overkill, but that's kind of the point :) Both materials are also challenging to work with, enough to make it interesting anyway.
