Does anyone out there know how the nomad range of gear is sized? The website is crap and they are not very helpful when you phone up. I have found a place that stocks it but wanted to try and get size right the first time. I tend to go for a roomier fit and im xxxl in ridgeline but have a xxl in a swazi bushshirt. Any help would be appreciated. Im 41 to 42 waist in deerhunter which is xxl.
