Really comfortable and warm merino base layer but the price will put some off
Weight:

The Isoler Merino base layer from Madison is made from 190gsm 100% merino wool with a tall zippered collar that is ideal for staving off frosty cold mornings as the foundation of your cycling clothing layering.

The merino wool is luxuriously soft next to the skin, and keeps you dry even when you're cycling hard. Even when it does become a bit damp from excessive sweat, it retains the heat so you never feel the chill.

The fit is really good, with a nice length in the body ensuring there's enough to tuck into your bib tights or shorts. The sleeves are generously long with nicely shaped arms and cuffs, and the collar is tall to keep your neck warm. The zipper lets you introduce some cooling air when you do get a bit toasty, such as riding up a long hill.

Flat-lock stitching is used throughout and provides added comfort, as there are no seams to irritate. There are some reflective details, useful if you wanted to wear it on its own in warmer conditions, but at this time of year it's a good foundation for layering with a jersey or jacket, or both, to suit the weather and temperature.

At £49.99 the Isoler is on a par for what you can expect to pay for a merino base layer, but it's nudging up against the likes of better known, and arguably more desirable, brands like Rapha and howies. It's also possible to pay quite a bit less than this as well, though our experience suggests that there's merino and merino, and you do get what you pay for in general.

The price puts it in sight of better known and more desirable brands and look the other way and you can pay quite a bit less for an equally good merino base layer. It's very good, but probably needs to be a bit cheaper.

It looks to be a really high quality item. I've found merino a bit of a revelation when worn as a base layer. Especially when wearing it on consecutive day rides when it's not possible to wash the item concerned. If your a sweaty type ( like me) there superb as they don't hold any nasty scents http://www.tinpony.co.uk/shop/?category=Sale+items

If you're going to continue spamming the site with your adverts, could you at least use a more subtle username?

Y'know, could could just be some random guy called LukePiewalker72 who HAPPENS to have some bizarre fascination with these products, but calling yourself Tin Pony really gives the game away...
