Indeed, many travellers like to bring along the sleep sack when they go on holidays. It weighs about 280g but despite its lightness, the sleep sack has plenty of uses.

It's convenient to lug around and even more useful for those with sensitive skin. It can be used as a blanket, to line sleeping bags which can be hot in this humid Malaysian weather or used for tucking in babies when on the move.

It's actually a sleeping bag of sorts and is made from cotton, silk and synthetic fibre. It comes with a pillow attached and is hypo-allergenic which is good for those with sensitive skin.

It's great for travellers staying in hotels, campsites, trains and bunkers and those who are stuck at the airport waiting for connecting flights or due to flight delays.

The sleep sack is available at most shops selling outdoor and camping equipment. It retails for about RM50, depending on the brand.

The best part about a sleep sack is that it's easy to pack into a suitcase or a backpack as it can be rolled into a drawstring pouch.
