Let’s face it, you don’t want to have your weekend trail run ruined because a summer squall soaked you to the bone. Next time, pack the Rab Phantom Pants. These ultralight rain pants take up virtually no space in your pack and weigh about as much as your typical energy bar. Once you have to break them out on trail, you’ll appreciate the robust waterproofing and high breathability of the Pertex Shield membrane, meaning you won’t have to slow your pace to keep from sweating. When the storm passes and the sun starts shining again, you can easily strip these pants without removing your shoes, thanks to the built-in ankle gusset.
