Summer coat

[GettingStuffed]

I'm looking for a waterproof(ish) summer coat that isn't too sweaty. I own one from mountain warehouse but its lining gets sweaty so if I take it off its really unpleasant to put back on. I've seen a protected species one but it's far too pricey and I couldn't find it cheaper anywher. Max budget £100

I've got a Protected Species mac and a commuter jacket (had both a few years and wear well) and they don't get sweaty at all. They are pricey though but they do sometimes have end of season deals with big reductions if you get on their mailing list.
My Didriksons jacket is also good for lightweight breathability but not sure what they do under £100. Cotswold outdoor sometimes have good deals.

Seasalt coats are excellent. I have 3 different styles. www.seasaltcornwall.com/waterproof-jackets-raincoats/lightweight-coat
