Check out Cabelas and LL bean, they both have tall sizes. Cabelas has lots of items in tall just do a search for "tall" then you can narrow it down for what you are looking for and it will only show you tall items. Don't forgot to search their bargin cave as well. On LL beans website when you click on an item it will say on the right if you can order it in tall. Usually 10bux more.
One thing to think about, Ive read many times cabelas is not known for making lightweight items. They are durable and will last but not lightweight. LL bean I have no idea.
My gear is no where near lightweight
