Like it a lot but a little heavy

Overall, I really like the bag and the modular system. There is a lot of good storage and organization along with great flexibility. I knew it going in but the one knock on this is it is pretty heavy.

Just What I was Looking For

I looked for quite a long time for a modular backpack. Something that could be and EDC and do some travel. Works for both. Really well built. Love the magnetic clips on the top.

My experience

Well the bag and accessories came in and they were very well protected in the shipping process.

I was glad to see that the bag was somewhat smaller then it appeared in the pictures and video reviews I could find (I didn't want a bag too big to carry around as an EDC bag).

The quality looks to be fantastic and very well padded. Zippers and stitching both seem indestructible and the fabric is very water resistant.

Basically for me anyway it is a home run and I couldn't be happier both with the bag and the customer service so far.

There are a few companies out there that make a really "good bag". But it is almost impossible to find a company that makes a really "great bag". Well done boundary, well done!

Best Functional Back Pack I've seen

this is my 2nd boundary purchase. I have a sling and now the prima system. the quality is top notch. the functionality is amazing and very detailed. the technology is over the top from the locking magnetic straps to the snaps of certain compartments so they are suspended in your bag. I've been showing this bag off to all that will listen.
