Zeal Optics have been an amazing sponsor over the last 3 years and super supportive of anything I do. Zeal Optics are just like me. Stoked to be doing what they do and with a real passion and "zeal" for the outdoors. Without doubt they make some of the best eyewear available on the planet!. Anyway, great company, awesome kit. End of story. Now watch the clip below.

NB. I swear I did not read that spiel off a prompter. It took about 100 takes just to bumble those few words out and that was the best of a bad bunch!

Right, how to win! I have a bunch of hats, (as you saw in the clip) and a pair of Zeal Optics Tenacity sunglasses with ZB-13 polarized lenses to give-away. All you need to do to be in the running is the below. Simple.

1. Answer this question: How many grey Zeal Optics hats are shown in the clip?

2. Email me (mark@markkalch.com) with your answer and Twitter name*

3. Follow me (MarkKalch) and Zeal Optics (ZealOptics) on Twitter and tweet the following - "I just entered to win sunglasses from @ZealOptics thanks to @MarkKalch. Stoked! You can too! http://bit.ly/brT99Q" (no need for the parentheses)

*If you are honestly not a Twit like so many of us, just email me the answer (and tell your friends about it!). If you are on Twitter, be nice and follow Zeal Optics and myself. Good Karma!

Easy enough? I will be drawing the winner at random on the weekend of the Expedition School (August 20-22).

First prize is 1 pair of Zeal Optics Tenacity sunglasses with ZB-13 polarized lenses plus a sweet Zeal Optics cap and stickers. I also have a couple of runner-up prizes of caps and stickers to give-away.
