Quite a few phones these days offer some dust- and water-proofing protection, but if you're serious about your outdoor mobile adventures you'll want a full-blown rugged phone.
Like the Caterpillar B15, which mixes your obligatory rubber and metal chunkiness and standard black/orange colour boldness with a surprisingly decent specification.
Well it's surprisingly decent in terms of your average rugged smartphone, though it won't have the iPhones and Galaxy S IIIs of this world too worried about having their glory stolen. Maybe just their lunch.
The Cat B15's hard-man credentials cover being able to withstand a 1.8m drop thanks to the shock-absorbent rubber around the silver anodized aluminium chassis, plus its IP67 certification means it's dust-proof and fine with a dunk in up to 1m of water for a full half hour.
Despite all that protection the overall weight comes in at 170g, though it is 14.95mm thick overall.
The B15's 4in display (480 x 800 resolution) is fronted with Gorilla Glass and the capacitive touchscreen works even with wet fingers.
On the inside you've got a MediaTek 1GHz dual-core processor, 512MB of RAM, a 5MP/VGA camera combo and 4GB of expandable storage. Android 4.1 Jelly Bean handles OS duties.
Given all that, the €329 price tag (around £285) sounds about right, and the Caterpillar B15 will be hitting the shelves where it hurts starting next month.
