The simple solution is to put the stuff you want to keep dry in a waterproof bag. There are many from which to choose. Most are made from black tarpaulin, which is not only heavy but creates a problem when trying to find bits and pieces in the dark confines of the interior.
I’ve recently found what I see as a perfect solution in the form of outdoor equipment-maker Lifeventure’s Dristore bags.

The Design
Dristore Roll-Top bags are made from ultra-lightweight 30-denier siliconised Cordura fabric with fully taped seams. Roll-top closure is completed with a single click-shut buckle and stiff webbing.
The Lifeventure range of bags is on the D of E recommended kit-list. The bags are colour-coded by size, and the blue 5-litre one I’ve been testing measures 260 x 470mm and weighs in at a paltry 39g.
The discreet screen-printed livery is in silver and applied to the inside surface so that it shows through the very thin but incredibly tough fabric.
There is also a small panel inside on which to write your name with a permanent marker pen.

In Use
This bag has travelled with me to Egypt and the Caribbean. Both trips involved day-boat and shore-diving where I had to transport my kit every day, and although it was dry on the way out it was always soaking wet on the way back.
To test the sealed bag’s waterproof qualities I used a lanyard and clip to attach it to my swim-shorts and went for a snorkel. It was filled with toilet tissue for the experiment (even I’m not stupid enough to commit anything of value on such a precarious test).
I needn’t have worried. The bag remained totally watertight for the 20 or so minutes of immersion. It floated, too, with the air around the contents being sealed in.
An added advantage of the siliconised fabric was that water immediately ran off the bag’s surface, allowing it to dry quickly. The Cordura material is opaque but allows light to pass through, which meant that I could easily identify the contents by sight as opposed to fumbling around and using touch to locate items.
When the bag wasn’t in use, it rolled up into almost nothing, so could be stuffed into a very small space.

The 5l size proved ideal for everyday essentials such as keys, wallet, mobile phone, camera bits and pieces and medication. It also took a pair of lightweight day shorts and a T-shirt.
For those excursions on which I’m likely to change locations mid-trip I’ll invest in a bigger bag, one that will take all my clothes and keep them dry when they’re packed in the same holdall as my sopping exposure suit, booties and BC.
There is one over-riding advantage to this type of bag; it can be filled with ice and cans of my favourite brew for chilled after-dive refreshments. In fact I think I’ll get another one, just in case.
