The lightest waterproof trousers we have on offer! The Halo range is spectacular value for seriously lightweight, fully waterproof gear. What's not to love about that?!

OMM says:

An ultra lightweight, breathable waterproof pant that packs down to the size of a tennis ball. Ideal for when you want to move fast & light. Constructed using minimal taped seams in a 2 layer waterproof fabric. When combined with the Halo Smock the Halo suit weighs a total of 175g.

OMM's Halo Pants Waterproof Overtrousers have articulated knees, taped seems, elasticated waist and Velcro closure ankles. That is a genuinely impressive set of features in itself but add to that the incredibly low weight of just 80g for a medium size and the internal pocket that doubles as the stuff sack and you are getting a fantastic pair of waterproofs. There are waterproof overtrousers with higher HH and MVTR values but at 10,000 for each it is more than enough for most people in most conditions.

Usually with gear like this the price tag then kicks in as the restriction for most people but OMM have kept the Halo range at an amazingly low price point through the use of their own fabrics. Trousers like this are designed for running events rather than hill walking. They won't be as strong or durable as hiking pants but that's not what they're built for.

OMM Halo Waterproof Overtrousers

Trying to cut down pack weight I tried these overtrousers. It is a revelation to be able to pop them into a pocket and still have room for other items. This means I always have them with me. It is not possible to put them on over boots but can be done over trainers which is what I now wear in the hills. Normally there's is no place to sit when you need to do this so balancing on one leg while struggling with overtrousers is an awkward compromise, however one which ensures I can keep warm when the weather changes and heavy rain or high wind settles in. I thought they would not be durable but after two years of use they are still in tact. The fabric would rip easily on barbed wire or thorns though but if they ever need patching this is a small compromise for their utility and weight saving. Thoroughly recommended.

Compact and effective

Very lightweight and compact. Tested in particularly exacting conditions: a day of nonstop pouring rain and strong headwind. Kept my legs dry and somehow didn’t get run-off into my boots. As with all over trousers they would be a pain to put on mid- hike but if you know it’s going to rain they are cool and comfortable enough to wear throughout. Otherwise I use a waterproof kilt which is much more practical to put on and take off in intermittent showers.
