Buffalo 4S Outer Reviews

General comments: Before purchasing a softie 6 sleeping bag, I used the Buffalo 4S Outer as an idiot proof sleeping bag solution for demanding military situations. Recommended by a Royal Marine friend who had served for 16 years, the bag did not disappoint and I used it for several years on exercise and operations. Although I replaced the bag with a softie 6 in most circumstances, I often paired the softie bag up with the buffalo when vehicle mounted in colder conditions. For example I used the combination for 2 months between Oct and Dec 1997 in Canada with regular dips to -25 degrees Celsius. Weighing 1640g it stands comparison to other more usual synthetic sleeping bags with wadding fills. However it is far more weather resistant and much warmer when wet than these filled sleeping bags. For military use it also has a superb centre zip which allows you to spring out quickly and easily. Most other synthetic bags snag and grip as you try to exit. The inner with a pile lining provides an instant sensation of warmth and breathes so much better than other bags that it is possible to use it in a wider variation of temperatures.
Pros: utterly dependable, long lasting, unaffected by stuffing and restuffing
Cons: heavy and not very compressible.

General comments: I bought a Buffalo outer back in 1989 and have still got it, though the rest of the infantry soldiers - who'd served less months than the Buffalo had done years - thought I was some sort of hobo. The thick pile meant I could get a decent night's sleep down to zero when wearing Helly Hansen top and Ronhill trousers. When wearing all my warm kit it was fine down to, say, minus ten or fifteen. Easy to get in or out of, you could even use it on stag on a frosty night - as long as the DS weren't about.
It's just a fleece jacket turned into a sleeping bag; warm weven when wet. I never understood why they used Pertex and not Goretex. That would be a piece of kit worth having. And you can bung it in a normal washing machine, unlike the current issue bag that fills up the average Vulcan Crusader twice over.
Pros: Great when working in cold, damp conditions when you are climbing into your gonk bag miserably wet. Chances are, you'll be half-way to being dry the next morning. Down bags are the bees knees for warmth, but what use are they when the rain's got to them? In temperate climes, you can't be pussy-footing around when you are shattered and it's roll mat down, gonk bag and bivi out time.
Cons: The pertex liner rips easily, and looks scrappy when sewn again and again. Slightly bulky; I couldn't imagine using an inner as well as, and man-packing it all. The head zip on the eskimo hood died early on... was it supplied by Karrimor?

General comments: I bought my Buffalo bag in standard olive green many years ago. as others have mentioned it wears well and is a great bag when wet. I remember having to faff about trying to find a store that did the Large size as I'm 6'2" ZFrom waht ican remember of the sales blurb it was important to get the correct length. Mine came supplied with a stuff sac and Compresion spider which to be truthful were't up to the same quality as the rest of the bags construction and soon fell apart. The bag does not pack down very small at all and you need a good quality stuffsac or dry bag to ensure you can contain it once rolled and stuffed down. The hood is great and you can cover your entire face the bag sort of doubles as a bivvybag and sleeping bag in one. I've taken it snow caving several times as its good in damp conditions and shrugs off moisture. I must admit I did use a thin down bag as an inner bag doing this as the outer on it's own would have been too cold. A very well made product but as others have said a bit odd...
Pros: Solid construction, great hood, durable and warm if sensibly used.
Cons: Poor original stuff sac and compression spider.

General comments: I got this bag along with the 4S inner approximately 1 year ago and it has been used on multiple trips since then. I used it on its own in temperatures slightly above freezing (we were camped just below the snowline) and it kept me just about warm enough with no clothes on underneath.
The bag also works very well in wet environments, keeping me warm even when the bag is damp. I have slept in it in soaking wet clothing and by morning I found my clothing was reasonably dry and I was still warm (Though this was in mid-winter, so I was in the bag for about 12 hours, it doesn't work so well when your not in the bag for so long)
The hood is a good design for very cold conditions, however in hotter conditions I find it can sit too tightly around the head and get a bit warm.
Pros: Stays warm when wet
Durable - Having used mine for about 20 nights and having not cared for it very well it shows no sign of wear.
Easy to wash - Just put it in a large washing machine, also it will dry much faster than a down bag
Easy to store, can be stores reasonably compressed
Cons: Bulky and Heavy for the warmth it provides
Hood can be too warm in hotter conditions

General comments: AS WELL AS THE SLEEPING BAG OUTER IVE USED THE PILE INNER BAG WITH A GORETEX BIVVY BAG , WHICH PROVED TO BE A GREAT COMBINATION. VERY WARM IN SUMMER/AUTUMN AND COME WINTER, USE BOTH BAGS TOGETHER FOR AN INCREDIBLY WARM NIGHTS SLEEP.
Pros: INSTANT WARMTH,ADAPTABLE AND DRIES QUICKLY
Cons: WEIGHTY AND BULKY, HARD TO COMPRESS ,BUT IF YOURE VEHICLE MOUNTED ITS NO PROB
