REI Trail 40 backpack

How do I calculate which size of the REI Trail 40 would fit?

Thank you

@BlueRidge Thanks for reaching out!

I happen to own the Lookout 40 and it's a great pack! I'm 6' tall and wear a size large as I have a pretty long torso. The medium Lookout 40 fits a torso length of 17-19 inches with a waist of 28-44 inches and the large fits a torso of 18-20 inches with a waist of 30-46 inches. The best way to determine your torso length is explained in great detail in this REI Expert Advice article. If you have any further questions don't hesitate to reach out. 

I hope this helps, thanks!
