A trusty whistle like the Fox 40 Micro is one of the smallest, simplest and most under-estimated pieces of survival equipment around. You can't eat it and it won't keep you warm, but we highly recommend you always carry one with you as it may be one of the most valuable aids available to you.

Like the Fox 40 Classic, the Micro is a pealess safety whistle with no moving parts, and is very loud - 110 decibels! It contains no loose parts so therefore has nothing to freeze, stick or jam. It is also waterproof and virtually indestructible.

The new slim design gives it a much flatter profile, making it easier and more comfortable to carry under clothing.

Included on many of Woodlore's kit lists, the Fox 40 Micro is ideal for use on our courses or simply when out walking the dog!

  Great little whistle - seems to be pretty bombproof and will work even if it gets wet. A no-brainer for the price!

  It’s light. It’s loud. It’s got the RM logo on it. What’s not to like? I bought a few to go in various packs and on a necklace arrangement, along with Uncle Bill’s tweezers.

  Great whistle. Very loud whilst still small and very light. I bought two for my kids for our recent hiking trip in the woodlands of North Carolina and they gave me a bit of reassurance that if we got separated they would have a means of signalling.

  Inspiration from the 'Out On The Land' book to make a neck lanyard. Useful item to have to hand.

  I have carried a fox micro whistle for the past 5 years around my neck, it never comes off me. The whistle is all plastic construction with no parts to fail or fall out, there is nothing that can go wrong with it. The form factor is very slim, I can wear it under a tshirt without it sticking out.. The noise generated by this is very loud, it makes your ears ring and can be heard from a long distance. I would suggest buying from a reputable retailer such as Woodlore because the fox 40 has been copied and sold as genuine on other sites. I will buy another one of these if I lose mine. Postage was prompt from Woodlore so thank you for that.
