Size Guide
Size & Fit Guide
Our customers rave about our fit, check out the reviews.

FRAHM jackets are cut for real men's bodies and action. We've subtly altered classic tailoring for more movement, for real life. Our jackets do not have a restrictive teenage 'fashion' cut. 

Size Chart: 




Size by your actual body measurements, not copying your size in another brand. Fit can vary wildly between brands and their size may not be ours.

HEIGHT: This is the easy one – measure yourself from the top of your head to your heel. (Sometimes easier to do against a wall we find.)

CHEST: To find out your chest size, take a tape measure and wrap it under your armpits at the fullest part of your chest.

ARM: Measure from the shoulder seam to the bony bit on your wrist (yes, that is the biological term).



If you can't measure your chest circumference, the best guide to size is your best fitting existing jacket or suit jacket. Then Live Chat us and we can advise what your size is.

"Tall" sizes are for very tall men, offering exactly the same jacket with significantly longer arms and torso. Don't buy one if you're above average - our standard sizes will fit.

If you have shorter arms, we will happily have your sleeves shortened from a minimum of 3cm for you when possible (most of the time it is). Typically alterations take 3 - 4 weeks.  

If you have any questions please do Live Chat or email us on



A trench coat is a defining city gent classic, but is fundamentally flawed - the most famous (and expensive) luxury versions are made with gabardine cotton, which looks smashing, but doesn't work when you really need it - rain! So, we did the obvious, adapting a classic to be actually (very) waterproof, with technical fabric leaders eVent.

Wear in all weathers, from 0c to 24c, in dry weather, gales and torrential rain via elegant matte eVent 20,000mm rated waterproof fabric. Built lightweight, with room to fit over a complete outfit or suit, it is also lightweight and extremely breathable, meaning it can be worn as part of a smart outfit in warm sunny weather.
