Description

You won’t forget to take this whistle on your next hike or trip.

It's become an important part of our EDC (Every Day Carry) over recent years: the whistle. The classic use of the safety whistle is, of course, signaling you're in distress and need help: three sharp blasts in succession, followed by a pause of at least one minute, and repeated until a response is received. The shrill sound of a whistle is likely to carry much farther than the human voice and require much less energy. Remember, the number three is key in distress situations: a distress signal can be three fires or piles of rocks in a triangle, three blasts on a whistle, or three flashes of a light. Worldwide travel expert Jodi Ettenberg has a great post on safety whistles. You might be surprised to read about the situations in which her whistle came in handy — read all about it here (her whistle is different than ours, but you get the idea).

Have a dog (or two or four) that hike with you? Train them to come to the sound of your whistle. It'll likely take repeated practice, patience, and lots of high value treats to train your dog to come to the sound of a whistle, but it can be very useful in situations when your dogs are off leash and you need them to return immediately. (If you're whistling for your dog, or just testing out your new whistle, try one sharp blast or two, and make sure to give enough time between blasts so that no one thinks you're really in trouble.)

Our Whistle Sternum Strap Half features a nearly impossible-to-lose whistle integrated into the male (usually the left) half of the sternum strap buckle used on our Brain BagSynapse 19Synapse 25LuminaryHero's Journey and Guide's Pack backpacks, as well as our convertible travel bags — the Tri-Star, the Aeronaut 45Aeronaut 30 and the Western Flyer. The Whistle Sternum Strap Half is available as an optional upgrade on all these bags: select one at the time you buy one of those backpacks and you'll receive it along with the standard sternum strap, allowing you to swap or carry a strap. The Whistle Sternum Strap Half replaces just one-half of the standard sternum strap and is also available on this page for purchase on its own for anyone with any of the above bags — but note that the Strap Half won't work on TOM BIHN packs made before about 2005 — those have a 1" wide sternum strap and this new whistle strap won't work with that. To install the Whistle Sternum Strap Half: simply remove the standard male half of the sternum strap half you've been using all these years and replace it with the Whistle Sternum Strap Half.

Available in Steel Grey if you want your whistle to be obvious and easy to see, or Bright Orange if you want it to be really obvious and really easy to see.

Sewn in Seattle

Our bags are designed and sewn right here in Seattle, Washington, U.S.A.

That allows us to be control freaks in the best way possible; we have direct control and oversight of the quality of our materials, our products, and the jobs and working environment that we help create. It also offers us a unique spontaneity: when we have an idea for a new product or accessory, we can design it, figure out how to build it, add it to our website and be ready to ship it out our front door all within just a few weeks. How cool is that?

Intrigued? You can find out more about the unusual way we do business on our Company Philosophy page.

THE BIHN Guarantee

Everything you buy from us here at TOM BIHN is satisfaction guaranteed. We’ve been in business since 1972 and we stand behind what we make.

If something goes wrong and it's our fault, we'll fix it for free. Repairs due to normal wear and tear or due to other things that are not our fault will be performed, when possible, at a reasonable charge right here in our Seattle factory where your bag was made. Defects in materials or workmanship are uncommon and almost always evident while the product is still new. Keep in mind that bags and packs are often subject to extreme wear in everyday use: do not expect them to last forever. Only true love lasts forever! You can expect a TOM BIHN product to give years and years of hard service.

    Perfect addition

    My twins are both headed to university this fall with their Synapse backpacks. The whistle is perfect for entertainment or to alert for help. I like that the orange is easy to see if it needs to be grabbed quickly.

    Sternum Whistle Sweetness!

    My girlfriend loves having this attached to her Tom Bihn Tote! Working late a Vet Clinic I was looking for additional security options for her. Having this whistle handy at all times creates peace of mind and it's so nicely built and subtle! Opted for the grey version so it blends in better. High quality at a super sweet price.
