Environmental Considerations

Wear more, wash less: it’s every busy adventurer’s dream…
We apply Polygiene™ to garments so that they smell less with wear and need washing less between use: ideal for that multi day getaway (and you’re doing your bit for the environment too).

Polygiene ™ is a silver based treatment that we apply during fabric production. The silver chloride prevents the growth of the bacteria that makes your clothes pong without interfering with the skin’s natural bacteria flora, so it’s comfortable and safe next to your skin. Polygiene ™ is bluesign ® approved (meeting the highest environmental standards) and lasts as long as your clothes do, so you’ll never need to reproof them.

The catch? There isn’t one! You can wear this garment day in, day out, and day back in again without causing a stink – winner!

Love this top

I dont do any running, I just use my gear for tennis and coastal path walking.
And I love Alpkit, this top is my favourite.
Attention to detail and for a great, sensible price.
Love the colour so much I ordered two more.
Thanks Alpkit.

Great t-shirt

Does its job as a technical garment, for very good price. Not too loose and not too tight, nice to skin feel. Designed as any Alpkit piece, with an eye for a detail.

Excellent quality & value

As usual with alpkit stuff, this tshirt is excellent value & quality. I love the orange colour. It makes a nhce change from the usual pink & blue. The back is a black mesh panel which I was surprised about. It's not really clear from the description but it's great. Better than i anticipated. Comfortable fit which is not too loose or tight. Fits true to size as I am normally size 10 & it fits perfectly. It's a good length too so doesn't ride up when I run. I do a lot of long distance trail running & this was very comfortable. I'll be treating my self to a vest too!

Great tech tee

I liked this t shirt so much that I bought it in both colours and I'm glad I did. The breathable mesh panel is great and the little pocket is also perfect size for your parkrun barcode. Best bit, no chafing.
