I like both aspects.
I like having AEGs that I don't see anyone else with (or at least rarely) and/or ones I really like - my first cap gun was an Uzi, so I had to get a TM Uzi...I love Bond films, so I had to get a PPK(/S). I love the bank robbery in Heat, so I had to get a Galil...I love Full Metal Jacket and I know I will, someday, own an M60...
As for clothing, I grew up in hand-me-downs and we never had a lot of money for branded clothes. Now that I have a salary, I can save up for some nice gear that also is perfectly suitable for trail walking; which I am getting into as well. So I have invested in clothes that should be durable, functional and tactical if needs be: TAD Gear, Merrell and OPS being the main ones. I loved the look of a PCU jacket, so I wanted one. The fact that it works flipping well in winter swayed my wallet. I wear what is going to keep me warm or cool and most importantly, comfortable. It can be a long old day and the UK weather is, as we all know, and unpredictable madam.
What is great about airsoft, and it echoes others; is that participants are, as a whole, pretty non-judgemental. 'What works for you', is my motto.
