Rab MeCo 165 LS Zip Reviewed

Written by

To be honest Rab's not a company that's best known for its base layers, having made a name and reputation based around its down and insulated products, so when the MeCo 165 LS Zip landed for test and review we weren't expecting anything special. Even more so at the idea of yet another merino/something else hybrid. OK we got it wrong!
Getting the name out of the way first the MeCo part refers to Merino and Cocona (a fibre derived from coconut shell) while the 165 is a reference to the weight - there's also a 120 option. The LS is Long Sleeve and the Zip refers to the YKK zip that gives ventilation. The Cocona is treated with "active carbon" which helps speed up evaporation of water through increasing the yarn's surface area. Combined as 35% Cocona and 65% Merino the idea is to have all the odour resistant and comfort properties of merino while adding the wicking and drying advantages of synthetic fabrics.
Testing over a continuous five day period the MeCo proved to be one of the best uses of merino in a hybrid fabric, retaining the majority of the advantages of merino while making a noticeabl;e difference on both the amount of moisture it can handle and the speed at which excess is evaporated. It's close to the feel of merino, if a little "thinner" feeling and while 5 days doesn't compare with the 30+ days we've worn a Chocolate Fish Merino for previously there was no noticeable issue with odour resistance.

Where the advantage of a hybrid material really stood out was moisture control; While merino will remain comfortable even when overloaded with moisture the MeCo just doesn't get to the same overloaded state in the first place. Drying times are dramatically reduced and the flat locked seams help eliminate areas that dry slower as well as giving a more comfortable fit. Unlike some base layers the MeCO dried uniformally after washing, so no damp cuffs or collar while the rest of the tee was dry.
In terms of fit the MeCo is close enough to provide both warmth and comfort without ever feeling like a compression base layer and with a quality zip that reaches to around a third of the body length there's plenty of options for ventilation when needed - the sleeves can be rolled up if necessary.

Verdict: It's not quite Merino in terms of feel and comfort but it's very very close and certainly feels more natural than synthetic. As a multi-day, cool or cold weather, base layer it's hard to beat with its fast wicking and drying a better option than Merino and durability is less likely to be an issue with prolonged use. Add in a noticeably cheaper price than 100% Merino and the MeCo looks a very good investment.
