Good bit of kit. Originally ordered medium size but was a bit tight. I’m 5ft 6in and 78kg. Large was better fit.

thermal long johns

Can never get any thing for the legs, long enough for me, but these are close enough. In as new condition....or were they new? and are just brilliant for autumn winter or early spring stuff. And cost about £6!! I shall use them for canoe/wildcamps, and some winter work. Superb value.
I have had stuff from GoArmy before, and it has always been spot on.

Strange cut

Strange cut. I'm an average 6' tall bloke, but these were very difficult to get past my knees. Did manage it but they kept edging down during the day. Warm when they were up, though.

British Army Thermal Long Johns Olive

Bought two pairs for shooting great fit. Really good quality. Sizing was spot on can’t wait to get out shooting these will be great for early mornings. Would also be great if working outside as well. Washes up very well and holds shape.

perfect

Been looking and buying long johns over this cold period and its hard to find something not too snug, lightweight and warm . . but fear no more here they are!
The best thing about them is no fly, no flaps for your bits to fall through, so very comfortable.
Stop trying other garments these are the answer for warm legs and knees.

Ordered two pairs. So impressed with them ordered another 2 pairs. Lightweight, perfect fit and very warm. Excellent.

Excellent

I am a 32" waist so had size medium. Now I have quite solid legs but when first trying them on I thought these were really tight. However, I soon realised they would slip under a pair of trousers without any 'catching' or bunching. They turned out to be perfect. Am delighted.
Highly recommended.
