John R.wrote a review of Flylow Magnum 2.1 Pant - Men's on April 9, 2019
Familiarity: I've used it once or twice and have initial impressions
Fit: True to size
I have had the "lab coat" top for a couple months and so impressed with waterproof that I got these to match (color and hopefully performance). Was hemming and hawing between L and XL--often L works for me for pants and underwear but current ski pants are XL, and so I went with that, and a good thing. XL fits but no extra room--so I'm saying true to size but if you are on the border go bigger. There are velcro sides on the waistband that let you cinch these tighter, but they arrived with those near fully extended--so if I slim down there is room to cinch in, but not much room to go the other way. I like the button on waist instead of snap--my last pair of ski pants had a snap that weakened and didn't hold over time. The leg length is about perfect for me--last pair was a bit long, and was always dragging on the ground and premature wear. The one possible complaint--they are short-waisted and a short zipper- (this seems to be the current style with men's pants). However, when you really need to pee and have a couple of layers underneath, would be good to have a little more room to work with--I'll see how these works.
There are also snaps that appear to allow suspender snaps if you prefer that to a belt.
This model is not the eVent Fabric of he Lab Coat--so I'll see if rain repellance is comparable.
The fabric is unlined, and so in cold/very cold layering likely needed.
