当你在寒冷的气候下狩猎或露营时，你真正不想淋湿的一件装备就是你的睡袋。如果你经历过不得不在大火周围花几个小时晾干你的睡袋，那么你就知道我在说什么。但是如果你背着背包在山上，淋湿睡袋往往就是一整天的雨（或者是在小河上时的失误）。如果发生这种情况，体温过低会变成威胁。所以，在你进入野外之前，必须花时间给你的睡袋防水。遵循下面的步骤，确保你有一个温暖、干燥的睡袋和舒适的睡眠。
When you are hunting or camping in cold climate, one piece of gear that you really, really don’t want to get wet is your sleeping bag. If you’ve ever had to dry your bag around a backcountry fire for hours on end, then you know what I’m talking about. But if you’re backpacking in the mountains, all it takes to soak your sleeping bag is a full day of rain (or a misstep when you’re fording a creek). And if that happens, the threat of hypothermia becomes very real. So, before you head into the backcountry, it’s essential to take the time to waterproof your bag. Here are the steps you’ll want to follow to ensure that you have a warm, dry bag—and a comfortable night’s sleep.
从防水压缩袋开始
Start by waterproofing your compression sack
把睡袋套着着塑料袋塞进一个干燥的压缩袋里面。压缩袋内部有防水，但重复的填充和打开最终会破坏防水。套袋子减少了压缩袋的磨损，延长了其使用寿命。即使压缩袋在持续浸水后发生渗漏，它也很好起到了辅助防御作用。当你把袋子塞进压缩袋里时，用你的体重把袋子尽可能的压紧，并把袋子里的空气挤出去。
Stuff your sleeping bag into a dry compression sack that you lined with a plastic trash bag. Dry compression sacks have waterproofing on the inside of them, but repetitive stuffing and unpacking will eventually destroy that waterproofing. The trash bag lessens the abrasion on the dry compression sack and extends its life. It also acts as a secondary line of defense if your dry compression sack does leak after extended submersion. As you stuff the bag into the sack, use your body weight to get the bag as compact as possible and to push out any air in the sack.
此时，只要你确定你的干压缩袋没有任何泄漏，你就可以走了。
At this point, as long as you’re certain that your dry compression sack doesn’t have any leaks, you’re good to go.
