- our body is working overtime, trying to keep useless water at body temperature. we must get rid of that water asap, otherwise our body - with its limited, tired, resources - will only be able to keep us warm to a limited extent.
雪季冬季扎营,睡袋要临睡觉前才打开以避免过早打开的睡袋接受吸收冷空气,要花更长的时间暖和起来。

我喜歡加一個Sleeping bag liner, 我用的是MEC Mummy Silk Liner, 回家後可以洗, 感覺更乾淨一點, 而且暖和一些.
