There are times when only 100% guaranteed waterproof bags are an essential item of kit. Such as:

* When you’re walking or mountain biking into a remote wild camping site or bothie.

* When you are kayaking or heading off for a Canadian canoeing adventure

* When you are moving from car or campervan to tent in the rain

* At a camping overnight festival

* When you need to keep a laptop, tablet or valuables protected while commuting to work by bike or on foot.

You probably won’t be surprised to know that my life requires such a bag. I often cycle to meetings with my iPad or MacBook in my backpack and I am frequently deluged by rain. I enjoy sea kayaking and do not want to face dripping clothes at the end of a tiring day. I spend a lot of time outdoors and quite often in the rain and it’s vital that my valuables stay dry.

This summer, the G-Force and I plan to tick off a few big rounds of Munros – as we train for the Artemis Great Kindrochit Quadrathlon – which means we will need a bag that keeps our kit 100% dry. The last thing you want when setting up camp for a night or sleeping in a bothie is a wet stove, food and sleeping bag.

Aquapac 28l Toccoa day sack

The Aquapac 28l Toccoa day sack is the perfect solution. It is made from the same ultra durable material (called 500D Vinyl) as a dry bag and with the same roll top design. In fact, the Aquapac roll down seal principle has been tested by Imperial College of London and certified to a minimum of IPX6, which makes them as waterproof as you can get without total immersion and can cope in the most torrential weather.

In addition, and this is what makes it a great outdoors bag, is the Toccoa has rucksack style shoulder and waist straps.

This is not a pack that you would walk all day wearing because it is not that sophisticated in styling or comfort but it is perfect for getting kit to a kayak, or while mountain biking to work or a wild camp spot.

It’s easier to use than a straightforward drybag because of the shoulder straps for carrying, yet it does everything that a dry bag does. It’s a drybag with add outdoors versatility. I’ve seen a few of these coming on to the market and it surprises me that they haven’t been with us for longer.

The bright yellow version is also perfect for commuting on a bike on busy roads.

The Aquapac 28l Toccoa rucksack drybag is £50. See Aquapac
