I bought the Pneuma Tank the moment it was released. Only I didn't make it up straight away because I didn't have enough bra strapping to match fabrics in my stash. I could have used my coverstitch and binding to finish edges and extend into straps (and I will do this one day), but I kept thinking how great the Pneuma tank would be if you could change the straps, on whim / with fabric choice, just like the XYT workout top.
I used the XYT as inspiration rather than use the actual pattern pieces. This is only because I prefer a slightly different neckline than the XYT. I used my support tank sloper to draw in an X back that would connect with the front of the pneuma tank. You could totally use the XYT pattern though...just remember to extend the upper back pieces to meet the front of the pneuma. If you lay the XYT front on top of the pneuma tank you will be able to see how long this extension needs to be.
I used elastic to finish the edges. I stitched it down with a zig-zag rather than my coverstitch because I was getting low on matching thread.
The bra part of the top is from cotton lycra and the tank fabric is a lightweight, cool knit remnant. I decided to leave the hem raw.
I would not be surprised if this becomes my favourite running top. I like top / bra combos because it is one less thing to pull on if you are exercising in the wee hours of the morning or if you are packing to go on holiday and it saves trying to co-ordinate bra / top in the dark, if, like me, you want everything to match. This top should be much cooler than my support tanks because the main fabric is lightweight and probably does not contain lycra and the style is loose fitting.
