ULA updated packs, "prior year" ones discounted

I’ve been looking at the Circuit and noticed the sale on their site. Called them to ask what the changes were for the Circuit, and they said:

• Front mesh is now stretch like some of their other packs
• Front-bottom material is now stronger (vs. old Silnylon)
• Weights are the same

So prior year packs are deeply discounted.
