Nice tank , light comfortable and socks sweat like a champ, my second IO Merino purchase, looking forward to trying the tracksuit pants soon

Altitude tank

I use this top as a base layer when kayaking and it’s brilliant!

Used as a base layer for winter cycling

good warmth and beatheabilty. Probably too warm for all season riding. Would love one in a mesh for summer if possible!

ioMerino Horizon Crew

I love this top. The fit is excellent and the weight is perfect for winter or summer wear. It breaths, is super comfortable and looks fantastic.

Love them!

They are great

Comfortable, great quality

Very comfortable and soft, good quality and fit.

Very comfortable

Soft and very comfortable, nice and warm. Great quality.

Note (as is shown in the images) it comes down to your thighs, so it keeps your backside warm but can bunch up a little in the front when you sit down. A typical compromise in a hoodie, personal preference whether you like it to end at your waist or further down.

My fav undies

Well made, natural and a supportive feel!
Will be my go to undies from now on

Two great brands and an iconic event

If my club sells a great running top I’ll wear it even if I can’t run an ultra marathon.
With the Yurrebilla Ultra Tee, SA Road Runners Club has paired the iconic gum blossom images we love with the tried-and-true comfort, durability and functionality of IO Merino's Ultra Tee.
The printed material is timeless so your investment will stay relevant for years to come.
