Lots of lovely comments

Had a lot of lovely comments about my new watermelon backpack
Its very comfortable to wear as a back pack. I know its meant to be a dry bag too, but ideally it could have done with a few more internal pockets to use as a backpack, otherwise all good

Delighted with my Salty Kit 30L backpack. Roomy enough for my work and gym stuff to fit in one compartment. It has kept everything dry as bones throughout a wet British winter.

Fantastic bag, great alternative to the musto waterproof 30L bag that is no longer available. The colour is great, along with the small pocket on the inside and outside (which the musto bag didn't have!) I love that the handles are detachable, a clever feature since handles tend to wear out first. I'm really pleased with my purchase. Thank you Salty Kits.

Brilliant bag

We took it on a trip to the USA and got many complements on the bag and people asking where we got it from. We have passed on your details and hopefully you may get some orders from the USA!

Great quality. Easily fits all swim kit, water bottle and other essentials into it and it’s so easy to use! It gives me peace of mind that my things are protected and can be taken with me even in the water !

Top quality, nice bag although a good alternative would be to have a clip fastening. Slightly bigger would also make it easier to get the phone out.

Silver Waterproof Phone Case - IPX8 rated

Great product. Was worried I’d ordered too large. But product fits in as cabin bag and is super comfy. I wore it all day when it was full and had no issues. And of course it’s waterproof.
Actually now my favourite bag!
