请教：鹅绒充气睡垫可否用于6000-7000海拔？

笨驴

个人感觉传统充气垫不能用于高海拔的主要原因是其不能有效阻滞热传导，但鹅绒的使用是否使充气睡垫成为可以用于高海拔的选择？
看到Exped DownMat XP 9 的介绍：
R-value equals 8; most sleeping pads we sell range in R-value from 1.0 (minimally insulated) to 9.5 (highly insulated)
求专业登山侠客们的意见：该睡垫可否单独用于6000-7000海拔？亦或配合蛋巢泡沫垫可用否？高海拔使用气垫是否存在其他问题？
谢谢先！

Maximum insulation from the ground with 3.5 in. of air combined with 700-fill-power goose down

UV and abrasion-resistant polyester fabric is nonslip and highly durable; high-frequency welded seams are airtight

Separators between down-filled baffle chambers prevent cold spots and create thick, stable and comfortable cushioning

Internal lamination technology dramatically increases the long-term durability and airtight quality of the mat fabric

Sleeping pad can be inflated with the included Exped Schnozzel Pumpbag that doubles as a waterproof compression bag

R-value equals 8; most sleeping pads we sell range in R-value from 1.0 (minimally insulated) to 9.5 (highly insulated)

这玩意隔热保暖没问题，只有两个要注意的事：
1、垫子太厚，高海拔帐内空间本来就矮，用这个更矮；
2、厚了以后两边不好处理（胳膊会没处放），所以只能用宽的（65cm?)，如果队友不是厚垫子则和你的空间也不好匹配。
