Constructed from the same 30D siliconised cordura as our Airlok drybags, the LitePak can be packed down to pocket size. 

Ideal for keeping in a rucksack when traveling for toting items when you don’t need your main bag. Invaluable for long trips such as gap year travels and expeditions, but also for short commutes by bike or just nipping to the shops.

The siliconised cordura is fully waterproof but the zips and seams are not taped. It is a great option for kayaking, fishing and sailing. This daypack comprises of a main compartment and a small side pocket. The bag can be stuffed into the side pocket for storage and transport.

The perfect size for valuables plus drinks and snacks or spare clothes.

My favourite travel accessory.

I reviewed this on my blog in December 2015 after plenty of abuse. It is still going strong today. It was so good that I bought a spare one and that still hasn't been used smile

Good but Strength is an Issue

Bought one July 17. Very compact and useful. Used for cycling to stow helmet and heavy duty D Lock. Do not overload it. The stitching at base has come apart on mine and when you hold it up to the light there are small fissures visible through the back section which look about to become tears.

Very good pack size and comfortable to wear for its weight, but stitching could be stronger...

Bought it about two weeks ago to be used as a spare bag for a planned trip in Europe.

Thought I'd test it out by using it for some light grocery runs on the way home.

It worked very well for the first few times, but the bottom came off earlier today while only carrying some milk and bread.

Slightly disappointed since this is rather different from the high quality Alpkit stuff I'm used to... Would try to send it in for a repair/replacement in the near future and hopefully would have better luck this time!

Very poor construction

During the first use of this bag I was using to carry my Canon EOS 550D with 28-80mm lens. I heard a thud behind me and found my camera on the floor, fortunately it landed in a pile of leaves and not on the rock next to the leaves. I would definitely not trust this product again.


We got Will’s Atom back and it was found to have a stitching fault
