110 daN is the a magic number in several German gliders. In the USA, they don't understand the difference between kg and daN, so we get converted to 242 lbs (about 5 lbs lower). Chute typically weighs about 14 lbs / 6.5 kg.

In the USA, you could do all of your training in gliders that do not require you to wear a chute, but some other countries are stricter about that. You will not be able to fly any contests without one.
