Almost everybody knows Tiger Balm, it's completely invaded western culture; but few know of a product that's probably 2x better at soothing/healing sore muscles: zingiber cassumunar balm (also known as Asia Balm or Yellow / Orange Balm in Thailand). The plant is similar to ginger, except it has anti-inflamatory and pain relieving properties, exhibits antimicrobial activity, and has antifungal properties against pathogenic fungi.

It is the main ingredient of the ointment. On the other hand Tiger Balm's primary ingredient is petroleum jelly, which has none of these benefits (although it does keep the skin moisturized and help reduce rashes). I let you decide!

I've owned many merino under layers, from many different brands; some last 1 season, some 2-3. Yet they are expensive (near 100 CAD$); why all the holes?

I bought some Merino Underwear from Ebay a few years ago. I've used them skiing, rafting, canoeing, rubbed them, scrubbed them and you know what? no holes.  

They came from Lithuania, cost 33% less than what you can buy here locally (of which Icebreaker is the most iconic brand). They won't wear through; I do admit they tend to stretch and become a bit loose; however that's no big deal compared to gaping holes I've had in Icebreaker and MEC ones.

So here is a link!

Or search for UT Merino on Ebay.com. The results from Lithuania with "Merino Wool UT" in the title should do it. You won't be disappointed :)
