This training backpack is compact and lightweight - and only holds what you truly need

* If delivery time is critical and you need to be 100% sure we can ship an item immediately, please reach out first

plus I feel the back support is better because the shape is ergonomic, rather than flat to try and fit in the metal handles and wheels like the 40L versions often do

Lash points for gear attachment and helmet carry

You want it snug enough to work but not too tight that its uncomfortable

If youre on a tight budget I suggest buying used (Craigslist, eBay, borrow your friends old bag) or checking out REI Garage for closeout deals on previous years models
