Hi,
I don't think you can apply the pockets while wearing the suit cus the ahesive takes 24 hrs to dry LOL!
The only alternative is placing the legs through an ironing board and strech it to exactly the outline of the pocket when you are wearing it. I don't really see any point to do this though as most of the time the suit is left to hang or is rolled up. This will release the tension of the suit at the pockets and in the long run will create stress points on the suit and it will break down sooner.
Halcyon has provided a how to on pocket attachment:
How do I attach my Halcyon pocket to my wet or dry suit?
Necessary Tools: chalk, small brush, small roller
Recommended Adhesive: McNett Seal Cement
1. Don suit and hold pocket in desired location. (Recommended placement is on outer-thigh to keep the pockets out of the flow)
2. Use chalk to outline the desired location for pocket.
3. Remove suit and place on a hard flat surface.
4. Apply first coat of Seal Cement around outer one-inch strip on both the suit and the pocket.
5. Allow the adhesive to get tacky for about ten minutes and then apply a second coat.
6. Allow the adhesive to dry until tacky, for about ten minutes, and then apply a third coat.
7. Again allow the adhesive to dry until tacky, about ten minutes.
8. Place the pocket on the suit in the exact location desired. (Make sure it’s correct since it will not move easily at this point)
9. Use the roller to roll the pocket on the suit.
10. Allow drying for at least 24 hours before diving.
