No BS: an honest review

Living in the UK, the weather is pretty unpredictable, so having a 100% waterproof bag is great. I've even had someone stop new to ask where I got it from on a train. It's been a fair few months since I've received the bag, I've been taking it around on weekend trips and also now to work.

At first thought, the opening of the bag was a tad small. I just about managed to fit a small box in which I didn't want to carry in a separate bag, my laptop sleeve just fits (I'm fully aware this is meant for clothes and small items like water bottles for the beach - but I don't live near a beach and I want to utilise this bag on the daily whilst I'm not traveling).

As I bought the white version, this rubs the dye off my clothes and on to the bag so it constantly looks dirty on the back. Wet wipes work to clean it off but it happens all the time, even from clothes I didn't expect work rub dye off like my raincoat! The box I also managed to squeeze in to the bag, has also dyed my bag blue on the inside (stupid me, knew I should have stuck to my comfort colour, black!)

Lockable - great safety feature I've not seen anywhere else on these types on bags.

Cons (don't get me wrong, I love using the bag on the daily but maybe these are more pet-peeves than anything really wrong):
I really wish the straps were a bit longer so I could cross them at the top or the hooks at the top were closer in a bit as the straps constantly slide off my shoulders.
When the straps are adjusted, I noticed that occasionally slide back down again.
You really have to think about how you need to pack the bag! Things get dropped right to the bottom so if you want to find something, expect to have to pull everything out.
I feel the inner net pocket is attached on the wrong side and it gets in the way when packing / unpacking the bag. It feels like it's there for the sake of it, no really purpose because I have to pull everything out anyway.

One thing to note, it's more a trial and error thought process for me, you have to roll the top 3 times for it to be secure. If you over pack, roll twice, you can totally unroll and pry the bag open if someone really wanted to, whilst it's locked.
That's my honest opinion about the bag. I love using it, but some parts definitely could improve.

Works great!

Finally had a chance to use this. Worked great for piece of mind when snorkeling and swimming. A++

Good but

This bag is really good it seems to be "water proof" it holds cold things and is able to keep cool if left in cool place... the only real issues I have with the bag.. 1 the straps are uncomfortable... 2 the could only supply a white bag everything else was sold out and could not find anyway to order other colours on back orders or something... otherwise seems to be a good quality type of bag
