I bought the 16 initially but exchanged for the 18 as in spring/autumn I want something light I can stuff in a bag but I may be wearing something warm underneath. Sizing wise I'd say it's your actual size without a thick top underneath. I suppose that's fair enough for a running jacket: I will use mine for walking but it's nice to have one that is actually shaped. I like the fact that the logo is slightly low key, I can't stand having big logos all over a jacket. I also like the cuffs, which are elasticated in part, so if you have short arms that helps keep them in place. Pockets are good, also hood. Bought in the middle of the heatwave, so don't know about the waterproofing but really hope it works. (I had to select a performance rating but haven't been able to test yet.)

Great light waterproof jacket!

Honestly, where do I even start with this, it’s genuinely changed my relationship with running coats for the better. I recently ran an ultra with this jacket on and it kept me completely dry through the constant rain. I find with most running jackets you end up wetter on the inside but the material of this was completely breathable. It’s also not very often you find one with taped seams either which is mandatory kit in a lot of trail races I enter. I’ve been looking for a running coat like this for YEARS and had given up searching because I didn’t think it existed but here we are. Life = changed.

Really versatile for waking or ruining

Super lightweight fully waterproof jacket. Great colour.
