Why we love the plus size Alpine Onset Merino 150 crew base layer

Finding technical outdoor clothing that fits women's plus size bodies has always been a huge struggle. This Merino-mix base layer brings technical features to plus size adventurers for the first time, up to a size 30!

Outdoor Research worked with plus-size people in the USA to re-create the patterns for their best selling products, using measurements from real plus size people. This means the arms aren't ridiculously long, the trouser rise works for bigger bums, and overall, the coats are shaped to fit the different proportions of plus size bodies. Hurrah! Technical outdoor clothing that fits at last.
