My peronal opinion: just grab Large.
i'm 5'8 200pounds, very athletic build, no waist eventually, big leg shoulder muscles etc gym rat...I can go medium easily but prefer Large just because its so much nicer when you sit, when you move your arms etc...and tech aint cheap, you never know if you...
Keep an eye on ebay, it pops up. I also never pay more than 70-80 for a windrunner, eventually they all come for 50% off.
I heard this carbon heather color and the black one they did another batch recently since it sold out immediately, so those 2 colors should be the easiest to get. Waiting for...
The thing is tops go well with various stuff, but pants only the same or similar top.
Used to buy everything Nike, when i figured i dont have a fit i stopped lol.
Tech fleece top goes well even with denim, cant say that about lot of sportswear hoodies, so i focus on tops and buy neutral tech...
I still cant get over the chevron removal...Trynna find everything i can in that style, new in Large.
This probably my favorite windrunner of all time, sadly a used M, gonna trade it up for a new style two tone tech hoodie.
I have av15 joggers, the model that has woven fabric on calves.
Quality wise not bad, probably best after tech fleece from nike, i have every line pretty much and av15 is only thing id consider aside tech...
Sizing Same, tts but i find the joggers not to be that slim in butt, L in both. Tight...
Standard fit is regular so usually size down? especially if youre between.
For example im between M-L athletic build but i always go for L in nike athletic stuff. Probably would go for M regular fit
Edit: Oh for the tech fleece stuff...Always L. Shorts, hoodies, pants. XL on the joggers is too...
