Ratings and Reviews

BR1 Hi-Back Trousers
BR1 Hi-Back Trousers is rated 3.9 out of 5 by 35.
Rated 4 out of 5 by from Fantastic quality - bad sizing for me I love Musto gear for my sailing. I have a BR1 jacket which I bought a year or more ago and it's brilliant for sailing / dog walking etc. I have worn it lot and it's still excellent. I also have Musto heavy weather foulies which fit well so it cannot be all me. I was so looking forward to these lighter trousers to replace my non-Musto no-longer-waterproof trousers and I ordered small. The waist was a good fit but the trouser legs were way too wide and much too long. I'd order a different size but I don't think there is an obvious one to try. I would strongly recommend this provided the sizing works for you.

Rated 2 out of 5 by from Very Odd Sizing The trousers were sized as large. I have a 34 inch waist and found them to be extremely snug and wouldn't fit over trousers. The fastening device was a metal clip. The partially elasticated waist didn't seem to have any give/stretch. The trouser length was the opposite and was a good few inches longer than my 31 inch leg. Overall very disapointed. Musto really need to sort out the sizing of this item and give clear guidance. I guess I should have paid more attetion to some of the other reviews which implied sizing issues.

Rated 4 out of 5 by from Size I’m a size 8/10 female 155cm. These are way too long. Otherwise fine. Why are there no shorter options?

Rated 5 out of 5 by from For the price, these are perfect. Excellent trousers, great at keeping the water off either in the boat or on long rainy dog walks. Extra lined backside and high backed, fleece-lined waist is also a bonus. I sized down to a Medium (I'm usually a large), guessing they would be bigger and I was right to do so. All in all a good product and was exactly what I was looking for.
