Another great product

The tank fits like a glove & soaks up the sweat really well whilst Im rowing & then dries quickly once I stop rowing for 10 minutes. Super comfy & keeps my temperature stable.

Great to hear Brian

Take this to the weight room!

OK--this is a men's shirt but that's what fits me best when I weight train. This thing controls the temperature--in my gym it's using hovering on freezing!!--it's long enough so it doesn't ride up when I do pull-ups, and it has a higher neck (see freezing temperature comment!) PLUS no one else has this tank, and it can be stinklessly for a week of cardio and work-outs.

Glad to hear you like it! Thanks for your positive review!

Perfect

No nonsense. Well designed. The wider shoulders are perfect under a hydration pack.
It doesn't need to be a fashion statement - it just works.

Less is More - More is More ... I needed more IoMerino in my Life :)

After buying couple of Altitude Crew Tops (and loving them) I've added the Altitude Tank to my Cycling Attire ... same Great Fit, Long Body Length, Comfort and Great Design as the Crew Tops ... without the arms ... Love It

Thanks for your review Damien! Glad to hear you're enjoy your new purchase. Sounds like your ioMerino collection is growing!

my husband loves his christmas presents.

the only problem i have is trying to get him to put them in the wash . He wears them for days at a time .Both the Altitude tank and the Keystone running tank are awesome .
They will be packed as part of him mandatory gear for the upcoming razorback run in the victorian alps.

'Perfect'

Just wanted to let you know I took your gear to a conference and then hiking in NZ for 2 weeks after! The stuff was perfect, no odour despite the humidity and could be washed and dried overnight! The tank tops can be styled for work or outdoors hiking which was really useful as it reduced my packing load significantly.

Fabric Guide

While Merino is an amazing natural fibre, not all Merino fabrics are created equal. At ioMerino, we make our own fabrics, using only the best quality fibres, and to very specific specifications that make the most of the natural benefits of Merino. All of them are 'Merino rich’. No cheap blends passed off as Merino. No cheaper scratchy fibres or synthetic substitutes to save money. No unethical production. And each fabric is made for a specific purpose. So if you see something with a small amount of elastase or nylon added, you can be sure it absolutely needs to be there to enhance the natural stretch and durability. 

It took every bit of our 140 years of experience in the wool industry to perfect our fabrics, but we think you’ll agree the end result was more than worth the effort.

Ethically Made. Ethically Sourced. Perfectly Natural.
