Shadow Guide 33 v2 arrived last night, I'm tired but was eager to go over the bag and try out a few things, why also comparing it to bags from Tom Bihn and other bag makers.
First impressions build quality and materials are of usual Tom Bihn quality so expect years of use out of this. I choose Ursa over black and .... it is growing on me. Ursa is a dark brown with grey tones that show up more on overcast days or morning light, disappears under yellow light. this is one fabric color that must be seen in person.
Here I find that cable locks work great on the main bag compartment. Put it through the two holes were the bag cable bunches up and the button comes out of effectively keeps main compartment closed.


This hack from a Tom Bihn video done by Zeke and is useful on any bag I HIGHLY recommend this hack (Carabiner is a 'S-Biner MicroLock' from Nite-Ize).

On a side note, the zippers on this bag are smaller so most small/mini locks and cable locks will not go with the zippers.
At 50% full the bag stands on its own, so long as its heavy at the bottom and the top portion of the bag is not too heavy.
Now for the Comparison: the SG33 in every shoot is 95% full. This is A45 next to the SG33. The A45 is only at 50% to 60% capacity, making it look smaller than the SG33.



The SG33 next to the Mystery Ranch UA 21, my current work bag.

A30 at 100% next to SG33.


Synik 30 next to the SG33. Note, the pockets on the Synik 30 are empty and only the clamshell part is full.

Between the two, the Synik 30 pokes into your back has it gets full why SG33 remains flat against your back no matter how full it gets.
The Daylight back pack and Minaal Daily v1, and Chrome Kadet Sling (my other work bag).




Side-by-Side comparison of the bags.



A few more hacks that I found here on the forums. This is one that is used for the Synik/Synapse bags to hold items to the bottom of the bag. You will need to get the waist strap that comes with those bags for this work, as the one that comes with the SG33 is bigger.
A tight fit, but it works.
Up to 3 hoodies or items can strapped to the outside of the SG33. With it on, ran with it and shook it violently, only dropping what was strapped to the bottom of the bag.
Well I hope this was helpful. Thanks Tom Bihn crew for creating another awesome bag.
