Stay hydrated while keeping that pesky snow out of places you don't want.
The Hydrastash Smarty vest lets you add a proprietary Hydrastash® hydration to your kit. Create a bib with your existing pants through the Hydrastash® SMARTY® Vest’s smart design - zip it directly into a SMARTY 3-in-1 Cargo pant to create a full seal or button the loops through your belt loops on any other pair of pants.
