i’ve just bought a sensas bait brolly which is a metre square and i reckon is much better/easier to handle than a proper brolly.
and does’nt get in the way too much.

Waterline fiberlite flatback!!
same as the tounament one from daiwa,, only better
better in the sense that,,its impossible for it to colapse on itself due to a safelock mechanism when the centerpole is moved to the secondary position,, unlike the tourny one!
nice discrete overcast colour too!

As with waders, I would buy the cheapest you can – had just as much life out of cheap brollies as top of the range ones over the years

Take a look here , good choice for you to look at , and full discription.
