The 300D Oxford weave marries comfort and durability.
The 300D Oxford weave is a lightweight polyester. While soft to the touch the Oxford weave makes this material coarse and heavy enough for encounters with branches and brush. 300D, the “D” stands for denier which is a measurement of the thickness of the material. 300D Oxford weave is a lightweight, flexible material with a clear back coating and a water repellent finish.
Nylon is strong and elastic,
but it can have issues with high temperatures and excessive drying can cause piling. For color it must be acid died which means it will have issues with bleach, fading, and urine.
Cotton is the cheapest and most comfortable of all apparel.
We all love the touch of cotton, but it’s durability is not suited for the outdoor activities of your dog. Cotton does not repel water, it wrinkles, and stains easily.
Neoprene is waterproof and holds heat.
It is much thicker and not as soft which means restricted movement for your dog. As it is exposed to the elements, gets wet, and dries it will begin cracking over time. Neoprene also tends to hold oder and stink more than fabrics

You may be able to find reflective dog vests for $6-$12, but, remember, you get what you pay for. A quality vest will be a little more expensive. You can expect to pay between $15-$24 for a high quality reflective dog vest. Reviews on cheaper vests can be misleading, because the majority of dog owners who buy cheap vests do not use the vest very often. A vest used only on occasion may very well last for years, but that is not because it is durable.
Think about the clothing you buy for yourself. Not many of us wear the same shirt every single day. If we did that shirt would likely not last very long. Dog owners who buy a higher quality reflective dog vest tend to be daily users. They may replace their dog vest each year, but they also get much more use out of it in one year than others get in a lifetime with a cheaper vest.
If you are rarely going to use it then you could opt for a cheap lower quality reflective vest. If you want a high quality reflective dog vest then invest a few more dollars to put your PUP in the quality and durability they deserve.
