Leader and tippet Use a leader of between 9-15 feet, tapering to about 3x. The tippet material should be between 3-5x depending on conditions such as water clarity. A factory tapered leader is preferable because of it's convenience, however some anglers create their own by tying together progressively thinner lengths of line. Waders Waders aren't an essential item for summer because you can wade wet on a nice day, however I prefer to use them year round. Lightweight are probably best especially if you're going back-country fishing and chest length if you're likely to be wading through deep pools.
Most brands are available with a neoprene sock or boot combination.
I prefer the sock as I can then wear a pair of felt soled boots as well. There are neoprene waders available, although they can be a bit too bulky to walk in and usually come fitted with a gumboot as standard, instead of a sock. However they're good if it's cold or you do a lot of night or lake fishing - cooler temperatures and not as much walking. There are quite a few 'breathable' brands of waders available, using GorTex or another similar material. They're great but expect to pay a bit more for them.
