There are now two Mountain Raid bags in the OMM range.
OMM suggest this 1.0 model is for 2/3 season use. Recent comments on-line would appear to suggest 1/2 season, as the bag is also aimed at the travelling market.
I haven't tried it in anger myself, however I can tell you that it isn't suitable for anyone over 6 foot tall. At 6' 2" the material is under tension at the head and foot and that would be the last thing you need if you're trying to trap air and make maximum use of the 100g Primaloft.
The zip is not on the side, but slightly offset across the chest. There isn't any neck baffle, which all of course makes it able to be compressed down to a ridiculously small pack size as shown in the photo.
I would advise this to be ideal if you have additional clothing layers for insulation to wear inside the bag. Experienced OMM Adventure Marathon users will be very interested in this, as it will still perform even if wet or damp. However for comfort and safety, I would certainly err on the side of caution if it was predicted to be a cold night.
Better still test it in the garden before you commit yourself to a night on the fells!
Both these bags can be 'uprated' using the new Thermartex Heat Reflective blanket, which is a very light and compact way to add more warmth in the unpredictable Adventure Racing weather.
The packed size is 19cm x 11cm (Dia) compared to the Mountain Raid 1.6 at 22cm x 12cm (Dia).

Manufactures comments The aim with the Mountain Raid was to design the bag which you would want to use when running on the OMM or other events/activities where weight vs. performance was critical. We wanted it to be warm enough for practical use, lightweight, have good performance and be compact.
It is the purist bag for the minimalist with Primaloft One® PL1 and Pertex Quantum a winners combination. The bag weighs 400g and stuff's down to the size of a Grapefruit, combining loose laid Pertex Quantum over 60g Primaloft One synthetic insulation on top and 40g Primaloft One synthetic insulation on the bottom, it features a full foot box with external hangtags to dry/air and has a cowled hood to keep your head warm with a offset 1/4 zip with again a P1 insulated baffle to protect against cold.
The bag also doubles up as a safety/emergency bag to carry with you at all times on the Mountains and in the Wilderness.

I bought the Mountain Raid for use on the OMM when my son started competing with me and stole my older KIMMLite down bag. The new bag packs down smaller, is lighter and performs better when damp but .... I have used it twice, once on the 2017 OMM when it was extremely wet with night time temperatures probably in the mid single figures. With a pair of tights and base layer I was comfortably warm and would have had a good night’s sleep if it wasn’t for the wind battering the tent. Used it again this year in very different conditions - dry and very cold. The early race report quotes temperatures of down to minus 12 but not sure if this was ambient or with wind chill. What I can say is thank god it was dry and I could add my change of tights and base layer to what I was wearing during the day - even then it was flipping cold and I got little sleep. Possibly the use of hand warmers inside the bag made the night just about bearable. On the plus side I didn’t die and I have all my toes. If I knew it was going to be that cold again I would definitely add a liner to the bag. In terms of quality it seems to be very well made, it’s easy to clean and worth the money. As far as fit is concerned, I am 6’1” and weight about 12 stone - it’s snug around the body and doing up/undoing the zip when you’re in can be entertaining as the puller doesn’t flip round into the inside of the bag. The draw cord makes an effective hood but I do find turning over in the night whilst dressed in synthetic fabrics does result in the bag staying still and me turning inside it which means my head being the wrong way round in the hood, which I have found a bit claustrophobic. On the whole a very good lightweight bag but don’t expect too much from it in very low temperatures.
The great thing about this sleeping bag is it's weight and size (I didnt find much close to this for the same price). I used it fastpacking and both of those were of utmost importance. As a summer bag it's perfect but it would be a bit cold to use at other times of the year. For me, and what I was using it for, it was spot on.
OMM have innovated and produced a light weight and durable 2 season sleeping bag. I used it with a silk liner on a wild camp high in the Lakes and had a comfortable nights sleep. The hood was well fitting and I found the central zip easy to use for getting into/out of the bag. I also plan to use it as a liner inside my winter bag for end of year bivy trips.
Wonderful, personal service - the sweets , card and check up call were all so refreshingly sweet in this age of mass commerce! We will certainly recommend you to everyone!
Im impressed with my purchase, The sleeping bag in light and packs as small as a can of beer! And the service was second to none! I will be buying from here again!
