I was wondering if anyone had experience with the sub kilo myself. Logged on and answers were already hear. I ordered the long today!It will be two pounds lighter than my old snow lion synthetic at 30 plus years old. I want a wm but cant afford it right now. I hope the rei bag lives up. I am six foot and maybe could have ordered a regular, but reveiws say shoulder girth is a bit tight on the reg. The long has additional girth.Long is a touch heavyer but still half what I was carrying! I just need a three season bag right now anyhow.wish me luck! At 150.00 delivered with tax, a hard deal to beat right now. I have been looking a couple monthes myself.
