Purchased medium, perfect fit over jeans, length ideal with walking boots, well made & comfy. Not fully tested in severe weather yet, but I feel that they will do just fine.

I came across New Forest Clothing whilst searching on-line for a waterproof coat. I ordered a long coat and pair of waterproof over trousers. Everything about this transaction was brilliant. The order arrived very quickly and I was kept informed at all times. I am absolutely delighted with my purchases. The coat is lovely, and fits perfectly with a little room for a jumper underneath if I require a bit of extra warmth. I chose the colour blue and it’s a lovely shade. All in all, I cannot fault this company at all. Very impressed with them and I am now looking at their woolly hats.

Having had a pair of over trousers for six years I was sad to see them break, but I've found their replacement with the Mac in a Sac over trousers a great improvement. Not only are the lighter and more breathable than my old set, but they keep out every drop of rain. I'm really impressed with my purchase.

Well made, durable and good value waterproof trousers in a great little pack. I use them for dogwalking and take them anywhere with me when the weather looks unpredictable. Would recommend these!
I got a size L, I am petite and slim, and I am not able to wear these as the elastic at the waist is painfully pushing against my stomach / body. Absolutely unable to wear and have to return. Otherwise, the product is well thought-through and while it's a little too baggy it's probably perfect to wear over other trousers (as it should be!). It'd be fantastic if the waist was much bigger, to accomodate all bodies. I'm usually a size M, but I feel like I'd need an XXL for these trousers.
Finally some over trousers without the stupid side pockets! These came really quickly and they fit perfect. I recommend you order your true size. I will be purchasing from Mac in a Sac again.
I'm really pleased with both my Mac in a Sack jacket and trousers. Really good quality, kept me really dry on my first wet dog walk since getting them, and big bonus they weren't all sweaty. Highly recommended.
These are super handy lightweight but robust. A must have for changeable weather conditions. Great value.
Ideal for my purposes. very compact and fit nicely. i have not properly tested yet but they seem well made.
Very good waterproof trousers - exactly what you need! I imagine the velcro at the bottom is handy for some (cyclists?) too.
