Be careful using stuff made for one activity for another. Where I notice this, for example, is a lot of hunting gear is basically made for sitting around- but if you're active, you need layers rather than one heavy garment. Consider also how bulky or packable the material is, that's important in some activities, not in others. Camo's great if you're not wanting to be seen, terrible if you are. Stuff flapping in the breeze is fine if you're walking around, not so good on a bike.
