I've bought 3 of these now so suffice to say I like them a lot. I was a little dubious about buying the small size (the only remaining size at time of writing) because the garment measurements are smaller than my actual body measurements, but actually it is a near perfect fit.
I have almost nothing bad to say about them. They should cost more than they do. Brilliantly practical coverall despite how garish they are (which is a matter of taste ultimately). The pockets are huge and the zippers are nice and tough.
The only thing I don't like is the pull strap (visible in product photos). It's stiff and it runs from the arse all the way to the neck (with a zip for your mates to access the handle and drag you around I guess). Considering I'll never need to be dragged out of a tank by my neck I have no use for this feature and it only diminishes comfort unfortunately. Maybe it will soften up with time.
I still rate it 5 stars and think it's a great addition to any Swiss army surplus collection, or just if you need a nice and hardwearing set of overalls. I'd buy the rest of the stock honestly but I have to draw the line of excess somewhere.
