Is a First Layer the same as a Baselayer?

Yes & no. We don’t use the word baselayer as this is more accurately used to describe tighter fitting ‘skins’ or compression garments. Our First Layer pieces are designed to be the start of your layering but you may decide to wear a tighter ‘baselayer’ underneath. Our First Layers work best next to the skin and use fabrics designed to wick sweat and dry quickly whilst feeling soft against the skin and minimising rub points. 

What's the fit like?

 As discussed above, our First Layers are different to Baselayers in that we do not make them skin tight. Most of our First Layers use our Contact Fit (you can find an exact Size Guide on each product page, plus a guide to our Fit), the fabrics work best close to the skin but do not need to be ‘sprayed on’. 

Can I wear these under a pack of vest?

 Yes! All our products are designed to be used in conjunction with packs and vests, though of course the lighter weight products may not last as long as a heavier weight equivalent. We have moved seams  away from areas likely to rub such as the shoulders and use flatlock stitches to reduce bulk and friction. Bobbling of the fabric is a normal part of wear and tear and will not effect 

How can I stop my First Layer smelling?

Wash it! You can find a full Product Care Guide here and at the bottom of the page. A number of our First Layers use Polygeine which is a long lasting treatment to the fibres that inhibits bacterial action. You can also use specific wash products designed for use on sports gear, that kills off bacteria without damaging or astringent detergents and high heats.
