干吗要买厚抓绒
好的保暖抓绒沉重昂贵没有压缩性塞包里占很大空间，要想防风还得多花钱。化纤棉袄完全可以便宜轻便可压缩，如果是差不多成本保暖肯定比抓绒强。 绒的触感好呀。。。。。。
再说，买来不见得是为了往包里塞，主要是平时穿么。。。。。。^_^ 有道理，化纤棉袄是不错的选择，重量上和抓绒差不多，压缩性和保暖性更好。
但是说回来，他俩又不如羽绒服。 化纤棉袄压缩性和抓绒差不多，我用primloft的和polartec的比过，都是200的。超轻羽绒服也许是更好的选择。 小棉袄没有弹性 抓绒应该可以作出来的 弹性可能关键不在填充物吧 抓绒柔软透气舒适，棉袄比较臃肿累赘，抓绒一般做layer，棉袄往往直接当jacket，棉袄比抓绒的防护性好得多，也比抓绒暖和得多。 个人感觉，小棉袄穿上象穿个了个壳；抓绒穿上就是穿了件衣服。 有没有这个可能呢？
历史上羽绒衣很贵重
所以抓绒其实起源于廉价的替用品。
当你感到寒冷的时候，
穿羽绒衣通常一定不会感觉热，
重量一定更轻
何必一定要抓绒呢。
个人习惯上，保温我尽量不考虑用抓绒的。
[ 本帖最后由 酱铺 于 2007-12-26 21:46 编辑 ] 俺推测：因为抓绒出汗湿透，还能保暖，羽绒不行？
在湿度大的寒冷地方，能明显看见人体大运动量之后，透过抓绒散发滚滚蒸汽。 原帖由 <i>greatlook</i> 于 2007-12-25 17:37 发表<br />
弹性可能关键不在填充物吧 <br />
羽绒的面料如果要做到有弹性 估计防钻绒就比较难 就像防水透气膜似的 G-TEX因为是有空结构所以木有弹性 S-TEX没孔所以能够做得有弹性 我觉得抓绒用来和其他衣物做保暖的组合，通用性要比单纯的一件棉衣好的多。
举个例子，典型的三层着装刚好能够合适周边温度，那走起来的时候可以不用穿外套，如果温度升高了，可以只穿个抓绒，停下来的时候再穿上外套。如果只是一件棉衣，不能那么方便吧 同意楼上的观点,还有可以参考穿长裤不穿短裤的感觉 各有优缺点，抓绒比化纤棉要更透气些。 LZ在找一种轻便、保暖、压缩性好、在潮湿状态下还能保暖的服装，
难啊，等待科技的进步。 "各有优缺点，抓绒比化纤棉要更透气些。"
这个不太理解。。
化纤棉应该完全透气吧，可能不透气的只是面料而已。
有可以解决透气问题的合适的面料吧？ 感觉marmot的神衣就不错，可当内中外层穿
轻，300克左右；防风、防小雨，透气性很好，就是保暖性稍差，个人感觉保暖在class 100和200的抓绒之间
不知道，marmot会不会出稍厚一点的 windshirt保暖性超过100？？
我穿件100的抓绒外边套个shehe的皮肤风衣，比windshirt保暖好太多了…… 原帖由 <i>酱铺</i> 于 2007-12-26 15:02 发表<br />

节选部分关于保暖层的推荐～
Options:
Synthetic High Loft: I recommend using high loft synthetic insulation such as Polarguard, Primaloft, Climashield which is large enough to layer over all your clothing (aka a Belay Jacket). High loft vests and jackets tend to be lighter and pack smaller than the more commonly used fleece.They break the wind better than traditional fleece, but don't breath quite as well.I use a down sleeping bag and/or quilt... but for clothing I think there is too much of a risk getting it wet... so I want my clothing to be mostly functional if they get wet. Related to this, since my sleeping gear is down, having a high loft synthetic insulation garment can provide extra insurance. See BPL's High LoftReview for more info. For an insulation layer down to freezing I would normally recommend a high loft vest.In increasing warmth Montbell Thermawrap Vest (lightest, most minimalist), MEC Northern Lite 2 Vest (best value), or the Patagonia Micro Puff Vest. For colder conditions I would suggest a jacket (in increasing warmth) Montbell Thermawrap Jacket (lightest), MEC Northern Lite Pullover (best value), BMW Cocoon (best weight/warmth but fragile), Wild Things Primaloft Sweater, or Patagonia Micro Puffball Pullover (great weight/warmth ratio).I used to use a Patagonia Micro Puff pullover but it was just too warm for most of the conditions I faced. I was comfy sitting around wearing the Micro Puff with a medium weight base and warm hat when it was 15 F.When I am active I have to leave the Micro Puff partially unzipped until is it below -5F. I switched to the Montbell Thermwrap Jacket because it wasn't as warm as the Micro Puff but could be used by with Thermawrap vest when I needed to stay warm in 0F temperatures. There are a number of other high loft jackets (typically insulated with Primaloft) which are not quite as light weight such as the REI Gossamer, North Face Redpoint, and Mountain Hardware Compressor. For harsh conditions I would recommend a hooded "belay" jacket with a durable shell like the Patagonia DAS Parka, OR Synchro Hoody, Integral Designs Dolomitti Jacket, or the North Face Optimus Jacket. Note: a belay jacket should be large enoughto fit over all your clothing. This way you can wear lighter clothing while active and put the belay jacket on over everything else when you stop and need the extra warmth without having to take anything off.
Down Insulation: for amazingly light, compressible and warm down vests or jackets take a look at Western Mountaineering, Montbell, Nunatak, and Feathered Friends.The updated Montbell Inner Down Jacket weights a mere 7oz with a full zipper and pockets. Historically I would have recommended avoid down clothing in all but the coldest conditions because there is a higher chance of clothing getting wet than a sleeping bag, and we all know how poorly down performs when it's wet, right? In a recent experiment done by BackpackingLight.com folks, it seem that even when you soak well designed ultra-light down garments with highly breathable shells such as the Western Mountaineering Flash Vest, that in less than an hour the Flash vest will have more loft than any synthetic vest which weights approx the same as the Flash when dry. Inextreme cold, down wins hands down provided you wear a vapor barrier.
Fleece (typically 100, 200 or 300 weight) have been the most commonly used insulation layer for the last twenty years.Reasons to use fleece include: durability, breathability, and fleece dries very quickly if it gets wet.If you want a fleece which holds up for many years I would suggest looking at high quality fleece like those made by Mountain Hardware, Patagonia, Montbell, Arc'Teryx or semi custom jackets from Beyond Fleece.I think Polartec Thermal Pro High Loft (which first appeared in the Patagonia R2/R3) is the nicest fleece material in terms of comfort and insulation / weight since it's weight is similar to a 200wt fleece, but it's warmer than most classic 300wt fleece. WindPro is one of the few forms of fleecethat is somewhat wind resistant while still being adequately breathable.I prefer high loft garments because they pack much more compactly, and because they provide significantly more warmth / ounce.That said, I will take sometimes take a 100wt fleece rather than my high loft vest if I expect the morning lows to be above 40F.There was a nice discussion about fleece as a staple for backpacking.
[ 本帖最后由 cachet 于 2007-12-26 18:55 编辑 ] 楼上这个引用不能说明说明问题,他说的是vests and jackets.我想让棉衣表现出更差透气性的原因很简单,不带膜的抓绒只有一层,而棉衣至少有3层(内衬、棉、外层），归结起来就是酱师兄说的，面料的问题，跟棉没什么关系
