What the UTMB Whistler fiasco teaches us about choice and power.

We were all pretty interested when we saw what we’ll call ‘The Whistler Fiasco’ erupt. Unsurprisingly, or actually, maybe a little surprisingly, chaos ensued.

You might only be one person, but together we’re a force to reckoned with.

Great Travel Pants

The reviews are very accurate on these pants. They are very soft and comfortable, they suit my petite frame and have washed well. Highly recommend these.

Stride Tracksuit Pants

SUPER TOP!

Love my new " Mongrel" zip up so much that I ordered another one immediately so that I have a reserve.
Super comfy and I wore it for days without it smelling. Easy to wash and dry and the design and colour combination are exactly to my taste! Great quality products!

Ultra Tee

This is a “MUST HAVE”!if your are hiking or trekking (or on the Camino). Dries quickly (overnight easily) perfect for travel. Great either alone on warm days or as a base layer on colder days. An INDISPENSABLE wardrobe item. Lasts for years (decades actually!) single most important item in your backpack.

Universal Tee

My girlfriend stole them :(

Cozy, warm and breathable, my favorite to relax in.
Only downside is they’re now also my girlfriend’s favorite to wear around the house. So I’ll need to buy a second pair.
Sizing: I’m 182cm, usually M/L. ordered L, fits well.
gf is 170cm and likes the loose fit

Love Love Love

I basically haven’t taken off this hoodie in the 2 weeks since I’ve received it. Incredibly warm and soft. I got a small and it fits true to size. Size up if you like a baggier fit. This hoodie is great!

Altitude Tights - Ready For Adventure

Such great quality

This top is just as pictured. It is so flattering! The material is extremely soft and it's nice enough to wear as a top without covering it up under your other layers.

LOVE IT
