I have many articles about getting outdoor gear on the cheap. Many of them I use myself.
And one item I’ve used for years and for so long I forget when I initially started using it? A Tyvek mailing envlope.
The type you can get or receive from the post office, a FedEx, or a UPS mailing center.
Durable, light, water-resistant, and just the right size to store maps or as a ditty bag. My 12″x15″ envelope does not even register on the scale.
There’s not too much more to write other than it works. It makes an excellent budget solution for those looking for something more durable than a Ziploc bag. As with all my favorite pieces of gear, I like it because it works. And after many nights out in the backcountry with this envelope, I can say a Tyvek envelope ditty bag exceeds my expectations for its use.
