Large size zip swaddle?

All swaddles in zip up seem to be only small size, then change to Velcro style once bub hits 6/7kg. Only ones I can find which keep zipping in bigger sizes are love to dream (don't like arms up) ergo cocoon (only has 0-3m & massive size 3-12m) and woombie (too thick for summer). Does anyone know of other brands which zip up past 7kg?
