finally one that isnt boxy

5 star rating July 12, 2026

ive got a load of these kind of jackets and every one of them hangs straight down like a bin bag. this one actually has a shape to it. the seams down the front make all the difference.

went with the size up and glad i did

5 star rating June 28, 2026

read the note about it fitting close so i sized up and its perfect. fitted through the middle but i can still move my arms properly. would have been too tight in my normal size i think.

ordered a second one two weeks later

5 star rating June 19, 2026

got the black first, liked it enough that i went back for the sage. should have just done the two pack at the start, would have saved myself a tenner.

thicker than i expected in a good way

5 star rating July 03, 2026

ordered it half expecting something thin and see through for the price. its not. it has a proper weight to it and holds its shape when you put it on.
