Exactly! It should fit snug. Not loose, when talking about jacket and pants anyway. Helmet too.
It is good if you can get a set that zips together at the waist. If you ever find youself sliding down the highway on your back, the last thing you need is for your jacket to start riding up on you.
Not trying to scare you. But things can happen very fast out there. I have been down more than once and good gear is what saved my azz! I have been riding since 16 and I'm 43...it can happen to any experienced rider.
What is funny is that I had been a Harley rider for the most part. Wearing the scull cap and tank top. When I got my sport bike, I gained a whole new respect for riding!
I feel naked if I dont have full leather on.
And yes, it may feel very weird or uncomfortable at first, but you get used to it.
You shoulda seen me trying to wear a full face for the first time!!! LOL.
Now I would have it any other way.
Good luck on you quest for shopping. Many of good points mentioned in this thread.
