This is a finetrack POLYGON NEST 4x3 Short sleeping bag for spring and summer use. I purchased it several years ago and used it about 7-8 times. I had it professionally cleaned and stored it at home. I am selling it because I bought another sleeping bag and no longer use this one. 【Condition】 - Home cleaned - I believe it is in good condition with no damage or stains. - From a layman's perspective, there is not much loft compression. 【Product Description】 An all-around model suitable for a wide range of mountain climbing scenarios in spring and summer, including high mountains. Ideal for 3000m class mountains in spring and summer. Also recommended for activities in severe environments where weight reduction is required, such as canyoning and alpine climbing. An ultra-lightweight and compact sleeping bag that can be relied upon even in harsh environments where it may get wet, such as long-distance trekking and canyoning. Uses the three-dimensional insulation material "Fine Polygon" in the middle layer. Fine Polygon is resistant to water, so even if it gets wet, it can suppress the decrease in heat retention. I am 173cm tall, but I used this short version to reduce weight.
