Hestra Merino Wool Liner Active

The Hestra Merino Wool Liner Active is a thin merino-blend glove liner built to be worn under a ski glove, not instead of one. Hestra's own performance block puts it at Warmth 2/8 ("Moderate"), Mobility 8/8 ("Second skin"), Durability 2/8 ("Light use"), and answers Waterproof with a flat "No." Those four ratings are one fact seen from four sides: the fabric is thin. Thin is what buys the dexterity. Thin is also what costs the weather protection and the abrasion life. That is a trade-off, and a trade-off is physics, not an opinion.

Fabric and construction

Hestra's spec sheet lists the outer as a 70% merino wool / 30% nylon tricot at 160 g/m². The blend does two jobs. Merino keeps working when it is damp — Hestra's words are "warming even when damp" — which matters in a layer that sits against skin and collects sweat all day. The nylon is there for wear life, and Hestra credits the synthetic with adding "extra durability."

The official feature list is exactly two items long: machine washable, and a puller at the cuff. That is the entire list. No membrane, no insulation package, no touchscreen print.

Warmth and weather

Warmth is rated 2 out of 8. Hestra defines that level as "Minimal lining for cool conditions or high-exertion use." Worn alone, that is a cool-day, high-output glove: skinning, the walk from the car, shoulder season. Alone, it is not a cold-chairlift glove.

On water, Hestra is unambiguous. The Waterproof row on the official product page reads "No," and the explanation printed beside it is: "The glove does not include a waterproof membrane. It may offer water resistance from its outer material but is not designed to keep hands dry in sustained wet conditions." Water-resistant is the ceiling. There is no CZone insert and no GORE-TEX insert in this liner, and Hestra makes no windproof claim for it either. Any listing that calls this liner waterproof is wrong.

Fit and sizing

Hestra sizes by hand circumference, measured around the widest part of the palm. On the chart published with this product the sizes land almost exactly on inches: size 6 = 152 mm (5.98 in), size 7 = 178 mm (7.01 in), size 8 = 203 mm (7.99 in), size 9 = 229 mm (9.02 in). Hestra adds that "the recommended size is an indication. Hands vary, and some models have a tighter fit than others."

PTO stocks one colourway, Charcoal (art. 34110-390), in sizes 6, 7, 8 and 9. There is only the one colour, so there is no size-by-colour split to sort out. One practical note: a liner has to fit inside your glove as well as on your hand. If your outer glove already fits close, a layer inside it will fit closer.

Who it is for, and who should not buy it

Buy it if you already own a ski glove and want a layer to extend its range, or if you want a close, light glove for boot buckles, skin-track transitions and the walk to the lift, where Mobility 8/8 is worth more to you than insulation.

Do not buy it as your only glove if the job is keeping hands dry. That is a membrane's job, and it means a Hestra model built on a CZone or GORE-TEX insert; this liner has neither. Do not buy it as a hard-wearing standalone glove either: Durability 2/8 is what Hestra calls "Light use," defined as "gentle everyday wear with minimal abrasion," and that is not a rating that survives daily pole grips. And if you want to work a phone without pulling the liner off, Hestra does not list touchscreen compatibility for this model; its Merino Wool Liner Long does.
