Weren't the Rebok On Ice jerseys in the 300s/400s as well?
The On ice jerseys aren't going to be something the Majority of the NHL fanbase buys and they will Default to the Premium tier they have been buying for the past few years. But there are a ton of Jersey Collectors who have been asking for a more true to on ice product for years, and this is aimed towards them.
The on ice jerseys haven't been available at retail since the RBK edge transition in 2007, and yeah, they were high $300s then. This is pretty much just the same price with inflation.
The Premium tier, which is what CCM and Reebok labeled as Authentic and equivalent to what the Adidas jerseys were, actually came down in price with the move to Adidas, and Fanatics is so far staying in line with the Adidas pricing.
