Re: clothing.
Have mooched around a few bike shops over the last couple of months and tbh some of the kit prices are taking the mick.
I tend to buy well buy once and am fussy with my climbing and hiking kit. Nonetheless there are some great bargains to be found and some items easily crossover into the cycling world eg wicking tops.
Last year I managed to find Helly Hansen Lifa tops dirt cheap. These are high wicking cool in summer warm in winter tops and usually retail at around £20. Bought 3 long sleeve and 3 short sleeve for £66 all in. These are pretty much unbeatable base layers and I have climbed in them for years. Great biking wear as they are tight fit. I still wear 2 earlier versions that I bought late 90's.
Odlo (Norwegian I think) make great mesh tops that for hot summer activities I have yet to find anything that beats them. Slightly looser fit but on admittedly rare hot days there is nothing cooler imo. Bought 8 in various colours year before last for £12 each. These literally last forever and I have a couple that I bought when I lived in the South and I have been in the Lakes 15 years now.
Btw I live in a part of the country where it is pretty normal to wear 'outdoor' kit all the time hence the amount of this stuff that I buy.
