discussion of water/running packs moved from this thread:
Grand Canyon – BPL Group Run
. . . . . .
Nathan HPL 20 is very popular among ultra runners doing 50 & 100 milers.
it can be a bit warm because it covers a large part of the back and shoulders, so best for cool runs not ideal for hot runs.
I have one. since I do not use bladders (run with 2 handhelds) I removed the bladder and bladder pouch, and use it solely to carry food and clothes.
its a pretty small capacity pack, so it forces you to only take what you need.
it rides very comfortably on the back.
p.s.
the Nathan HPL 20 does not weigh 6 oz.
that is basically a lie on the Nathan web site.
Mine weighed 279 grams (9.8 oz) before modification and without the bladder.
my slightly modified and no bladder Nathan 20 weighs 241 grams (8.5 oz).
