Yes , the inseam is 37 for a "Skinny Guy" fit tag size 34
Where are you copping from?
NF does hem them for free ( through their Tate and Tokyo webstore) but you're going to have to know your preferred length...
Yes, these do come a little longer and you should have them hemmed to your height.
Make sure to leave in room for honeycombing and cuffing... I always err on the longer side because lets face it, I'd rather have jeans fit a little too long than be a little too short!! LOL
Edit- I see you are in SD.. you can always order from Nordstrom, get free shipping and see if they'll hem them for you for free..most likely they will...
Here's nordstroms NF inventory
