Berghaus Deluge Overtrouser 2010

Berghaus has long been associated with making practical waterproofs for the hillgoer. The brand produces both technical waterproof trousers for the mountaineer as well as more down-to-earth rainwear for the hill-walker. The Deluge boasts very long side zips, which makes it instantly attractive to anyone that struggles to fit overtrousers over their boots.

The most important feature on the Berghaus Deluge Overtrouser is definitely the long zips, which have double stormflaps and press studs on the outside to help keep the rain out. Surprisingly though there is no adjustment at the ankle cuff, unlike some other trousers. The waist is elasticated, with an elasticated drawcord and toggle. There is a mesh lining around the waist with a nylon lining running down each leg. The waterproof material is Berghaus’s own AG2, which has a hydrostatic head of 10,000mm as well as reasonable breathability. It’s not the most waterproof and most breathable fabric available, but then this is a lower-priced trouser with lots of other features that are missing elsewhere.

Compared to some other trousers here the Berghaus Deluge Overtrouser are rather heavy and bulky, although that in itself is not enough to dismiss them instantly in my view. Grab them from your sack and the long zip really does appeal; although having opened it up, the mesh lining then does get in the way a little, which sort of counteracts the benefit of the trousers to some extent. For me mesh linings are always more hassle than they are worth and I’d certainly prefer a pair of trousers without such a lining. But once on they feel pretty good. Doing up all the press studs on those side zips may be a hassle for some, but I’m happy to do it to keep the rain out, and it only has to be done once. The cut of these trousers is a little baggier than others, which may help them fit some people with chunkier legs than me. There is no adjustment at the cuff to really snug this area down, and like others they still ride up a bit when scrambling around with knees bent. So I’m in two minds about these as I like the side zips but not everything about these trousers.

How waterproof?
You’ve got a full-length side zip to help getting the Berghaus Deluge Overtrouser
Deluge Overtrousers  on and off, and happily this does get a double external stormflap so I would not expect this to leak. In my tests it did not leak, and I think it would be hard to get it to leak! So thumbs up on staying dry.

The Berghaus Deluge Overtrousers have very long side zip makes fitting easy; double external stormflaps on zip keep out rain; drawcord waist is easy to adjust; mesh lining adds comfort. They relatively heavy, though; fabric does not have the performance spec of higher-priced options here; fit not as close as others; mesh lining can get in the way when fitting. In summary, good general trousers where the long side zip is a real benefit, but other features are better elsewhere. They won ‘Best Value’ in our test.
