Rock Climbing Clothing

What is the right rock climbing clothing? When you are rock climbing it is good to wear
comfortable, light and not particularly large clothes.
Your clothing must protect you from the sun and the wind and don't hamper your movements on the rock. At stores you will find special rock climbing clothing which is well designed and comfortable but a little expensive. Since we are not talking about ice climbing or mountaineering, a simple training suit is suitable. On summer a simple t-shirt and a stout pair of shorts are what you need. On autumn and spring, always have a fleece or a pullover in your backpack.
