Quick Summary
The OMM Core Beanie is a yellow, one-size insulated hat made with PrimaLoft ACTIVE fleece. It weighs 18 g and is described as packable, so it can be stowed in a pocket, vest or pack.
The fleece is stated to retain insulating properties when wet and to be air-permeable when not under a shell. These details do not mean the beanie is waterproof.

What to Compare Before Buying
- Fit: One size is specified, but no head circumference or fit range is provided. Check the sizing if you need a particular fit.
- Weather protection: The wet-weather claim concerns insulation, not waterproofing. Consider whether you also need a separate weather-protective layer.
- Colour: Yellow is the selected version. Navy, Grey and Black are also named; check that the selected version is the colour you want.
- Fabric weight: The 125 g/m2 figure describes the fabric, not the beanie’s total weight. The listed garment weight is 18 g.
Who This Product May Suit
The beanie is presented for trail running and hiking. Its low stated weight and packable design may be useful when you want a head layer that can be stowed between uses. Its air permeability when not under a shell is relevant when comparing headwear for changing activity levels. It is not described as waterproof, so do not treat its wet-weather insulation claim as rain protection.
Choosing the Correct Version
This page describes the yellow, one-size version. Other colours are named, but that does not establish which versions are available in any particular offer. Check the selected colour and size before choosing.
Packing for a Changeable Trail Day
The stated 18 g weight and packability make it straightforward to plan around the beanie as a layer to carry rather than wear throughout an outing. Stow it in an accessible pocket or pack compartment, then decide whether to put it on as conditions or activity change. If rain protection is also needed, plan for that separately: retaining insulation when wet is not the same as keeping water out.
Before You Decide
Check that one size is suitable for your fit, that Yellow is the intended colour, and that the beanie’s insulation and air-permeability details match your needs. Treat it as a head layer, not a waterproof hat.
