This is the best thermal insert I ever had! Durable and works as claimed. Not to mention aesthetically pleasing too.

This was my first thought on the Prima. Just opening and closing this amazing construction is truly satisfying. I travel a lot and this backpack makes me look forward to the next trip, having my camera my lenses packed just as comfortably as my other things.

If you’re on the fence it’s time to take action you won’t regret it. Customize it to your preferences!!

So far I’m pleased with my Prima backpack. It’s really well made, every element seems to be made with great care and top shelf materials. I like all the hidden pockets and overall it’s well designed. My only minor issue is that the camera case is just too small for my gear so I need to either not use it or upgrade to the harder case. Excellent overall.

This key clip goes well with my prima system pack and made with excellent quality materials. Boundary supply has do it again,keep up the Great work guys !!!!!

This key clip goes well with my EDC and works well with my prima system pack. This key clip is made with excellent quality and see it lasting a very long time. Boundary supply is my #1 in my book, keep up the great work guys!!

The design is unique and allows for camera and gear to be carried efficiently.

Just the right size for both toiletries and electronics. Not a ton of organization on the electronics side, but suits my needs nicely. Can even fit a whole Nintendo Switch with controllers attached!

I’ve had my Prima backpack system for about 2 weeks and I absolutely love this thing. I know there may be some growing pains as I use it more but to date I’ve used it as my daily carry (laptop, rain jacket, bike gear, Knick knacks), taken it to an overnight business trip, and on a 4 day weekend trip. I have to say, my favorite part is the comfort of the straps and back padding. I honestly barely feel the bag on my back. Next favorite is the field space, but I have to say I’ve never had a tech kit or anything similar before. The integration of the system is really easy to use and transition between just the bag or all three pieces. On the negative side I’ll mention two minor items: 1) the bag doesn’t stand upright. 2) the bag can be a little awkward to pack with the whole system in place. Thanks Boundary for a fantastic product!

It is incredibly practical and of high quality. I am very happy that I ordered this accesoir to the backpack.

I used it right away for my first trip, it was great as I was able to stow my spare pair of shoes well in it. It is easy and quick to attach to the backpack and made of very high quality material.

Super Simple and efficient. awesome material

The Prima System bag is able to fill every demand that I need an everyday bag to do - and more!

日本国内から注文し、発送から1週間ほどで到着しました。サポートは英語なら当日または次の日には返信がきます。 製品は機能性が高く、アウトドア、普段使い、自転車など何でも使える万能バッグです、 私は痩せ型でクッションの少ないPCバッグだと背骨が当たって痛くなりますが、この製品は背骨部分に窪みがあるので痛くなりません。そういった細部までこだわった点が随所に見られます。 他の方も挙げている通り、この製品が1万弱で購入できるのは非常にコスパに優れた製品だと思います。 予算15000円以内でPCバッグをお探しの方は候補に入れてみてはいかがでしょうか。

It's all I need in my everyday commute. Really nice quality!

I like how the two items can snap together or be separated, giving some clever packing options.

Seriously one of the best backpacks for my daily commute. I put everything i need plus many clothes. It is waterproof made using good quality materials. Loved it

the fabric feels great and heavy. It seems quite durable and fits nicely, not too loose or slim. I am 183cm high and weigh around 75 kg work out quite a lot (calisthenics and climbing) and ordered a size m.

I recently picked up the prima system backpack and it’s been awesome. I needed a pack to carry a camera and maybe a lens, some travel gear and my laptop and this did it all! The materials are excellent and good functionality. The space under the verge case when in the bag is kinda odd and could be improved. I just throw a jacket in there, but apart from that I’m loving it!

I love the modular functions of my new Boundary Errant Backpack and the HT Key Clip is a great, easy access option to complete the package!
