Top-notch products as stated on tin, arrived quickly ⭐⭐⭐⭐⭐


An excellent product, couldn’t be happier with it. Fits perfectly

Suzanne Bentley
Pleased with my top

Came promptly- as described. I am size 10/12 and ordered large because medium not available. It’s roomy - space to fit extra layer but that is good. Seems very well made. Second hand but very few signs of wear.

Smock review

Smock came very promptly, like brand new but sadly a bit on the small side. Good value & good customer service.

Great piece of kit

A very comfortable and surprisingly warm garment. I've been wearing one over a short-sleeved T-shirt for walks in the recent cold weather and haven't felt cold at all. Also very light, about 600 grams in XL, and packs down small. I'm 6' 2" with 40" chest and bought XL after reading other reviews referring to the small sizing. There is plenty of room underneath for extra layers but I think the L would have been too snug across the shoulders. XL is 28" pit-to-pit, 34" collar to hem at the back and 21" sleeve length. Mine was Grade 1 but showed no obvious sign of wear. Efficient ordering process and quick delivery from Goarmy. I'll be back!
