Something that I learned with bulky hunting clothes is that the string may not catch your sleeve on the wrist or your forearm, but it may catch where there is slack in your jacketin your upper arm area, around thebicep, when your arm is extended. This was an issue with my cold weather coat, not when I shotat ground level, but only when I shot from a stand and bent at the waist to shoot close. The material around the upper arm would kind of bunch up and stick out enough to catch the string.
