3rd Jan 15:375 StarsThis to fits really well. Love thumb holes to keep hands warm, but also it has nice detail on the back which makes it look stylish. The length is good too so it doesn’t ride up the back.
28th Dec 16:475 StarsBought as a gift for someone who is passionate about the environment - she loved it, also the extra coverage provided for wrists to increase circulation to her hands whilst working outside in cold weather. Great value for money too.

13th Dec 11:355 StarsGreat fit - very comfortable - great service.
12th Dec 18:304 StarsSlightly thicker and tighter than my previously purchased pink one. I have kept it and hoping it might stretch a bit.

19th Nov 18:054 Starssame as before review!
19th Nov 18:054 Starsbeautifully quality feel against the skin. I am petite and usually take the smallest size on offer. I ordered the 8 and 10 only because when running I prefer a looser fit. The 8 fitted very snugly but the 10…
18th Nov 11:135 StarsI love the longer sleeves and thumb slits for keeping my wrists and hands warm.
