"But if you like to believe that it is a gimmick, go ahead, I won't get upset."
I've only tried Sternum straps a little, with no benefit noticed.
This is one of those features people should try, and if you like it great,...
"The sternum strap is great for people with non-trivial pectorals and/or broad shoulders...You bird-chested guys don't have this problem.
"dissing the sternum strap" = yet another example of people ascribing their personal circumstances to everyone else."
Uh-oh - I must be a bird-chested guy.
Maybe it was Ray Jardined that I read that said Sternum Straps constrict breathing. Maybe he's bird chested too?
Some birds have large chests, like Turkeys.
Seriously, someone asks about Sternum straps, I think they got the full spectrum of opinons about this, backpackinglight is a good thing.
