UOG TOP PICK - OMM Classic 25 - Best for Adventure Racing, Superlight Backpacking and Events - We've singled out OMM's Classic Packs as one of our top recommendations because it offers a superb range of features suited to ultralight backpacking.

Grams are shaved by using a lighter weight fabric therefore not as durable as the RL (Rugged Light) models but for the hardcore its weight that counts above all. Supplied with an internal Duomat that works as a padded hipbelt and a torso length sleeping pad. This 25L version has the same features as the 32L version but a shorter back and hence smaller capacity.

The Mountain marathon has many of the features of the other packs in the OMM range but is made with lighter fabric. The only compromise is therefore durablity over its heavier stable-mates.

Great lightweight backpack

I have been very happy with this backpack for lightweight backpacking. Both last year and this year I took it on 18 day backpacking trips around China as well as on a 10 day trip in Europe this year. I have managed to keep total weight under 6kg on all 3 trips which means I can carry it for reasonably long periods in comfort. I am a 5'3" 47 year old female and appreciate the shorter back length of this model. I can fit everything I need for my trips in the 25 litres and also have space for water bottles at the side. My packed bag is within the hand luggage size and weight of all airlines I have used. I also got some lightweight drybags after contents getting very wet on the first trip. I now pack most contents including clothing in the dry bags, which also makes unpacking and packing easier. I can fit in 3 lightweight outfits, small packable waterproof jacket and trousers, sandals, small wash bag, first aid kit, phone and charger, small packable backpack and handbag, a few other little bits and pieces and a liquid bag for flight in top pocket. That's all I need for a trip and it all fits with a bit of space left. It still looks in great condition after the 3 trips it has done and I hope it will last for more to come, but when it eventually falls apart I would be happy to replace it with another.
