Unfortunately there is not much profit in a dealer having a lot of jackets and stuff in stock. I know it is easier for the consumer, me, but most dealers just don't want to tie up money on stuff sitting on racks.
Now if you are near or in a big city, you may have a dealer that does stock stuff, and a couple come to mind such as Neihaus, Gene's Gallery, Iron Pony, and of course places like Wing Stuff, and Whitehorse Press, and other suppliers. But who lives close to these folks, Not me!
So if the chance permits, I will go to a big vendor show like Wing Ding, Americade, or something similar and shop there. I bought my present First Gear Kilimanjaro jacket at a winter show in DC. I used to spend a bundle at the old Rider Rallys! And of course you can shop online but then you have to be willing to deal with returns if you goof up the sizing on the order.
Fortunately right now I am pretty happy with my jackets and so forth, and helmets so I am not looking but I understand your concerns.
Bobs cycle supply in Roseville MN. They should have the summer stuff out. You could call to see what they have on hand. Dr Mudspringers is still waiting for some of the new stuff to come in. If you can wait until the first weekend in May, Dr Mudspringers has there open house with some good buys.
