Denier is only how touch the fabric is, it has no bearing on how warm the blanket is. To determine how warm a blanket is, you have to look at the fill.
100 gram polyfill = light
200 gram polyfill = medium
300 gram polyfill = heavy
350+ gram polyfill = very heavy
600 denier = not very durable, ok for turnout with horses that don't play rough
1200 denier = more durable, can put up with normal wear and play for the most part
Ballistic material (3000 denier + ripstop) = very tough.
Generally speaking, this is what I do (degrees Celsius temps)
~ -5 to 5 = light
~ -5 to -15 = medium
~ -15 to -25 = heavy
~ -25 to -35 = light+heavy
Colder than that I may put on the medium and heavy blankets.
