Men's Fit Guide

Though each Patagonia product is designed and shaped specifically for its intended use, Patagonia generalise their fit descriptions in four ways:

Formfitting: Conforms to the body’s contours.

Slim Fit: Closer-fitting. Slim-fitting technical garments may be worn over baselayers and light midlayers.

Regular Fit: Neither slim nor oversized. Regular-fitting technical garments may be worn over heavier midlayers.

Relaxed Fit: Drapes loosely on the body.

How to Measure

Sleeve: With elbow bent, measure from the center (back) of neck to elbow and down to wrist.

Chest/Bust: Measure around your chest/bust, just under armpit.

Waist: Measure around waist at the smallest circumference.

Hips: Stand, feet together, and measure around the largest circumference at hips.

Hands: Measure around the fullest part of the hand, not including thumb.

Inseam: Take a pair of pants that fit well and measure from the crotch to bottom of leg. All pants come with a finished hem.


The R1 is a classic combination of durability and comfort - built to offer complete versatility on all alpine endeavours. The Regulator grid fleece is included to provide outstanding stretch, breathability and compressibility.

After many years of tackling alpine summits and weaving through backcountry powder, the R1 fabric has compiled quite an extensive resume. The exceptional R1 stretches, breathes, wicks and warms, and the addition of a full zip delivers versatility. The unique interior grid is constructed from Polartec Power Dry polyester fabric, allowing the jacket to compress to virtually nothing - perfect for the space conscious alpinists. The terrific feel is complimented by a technical fit to ensure you remain warmth without compromising your comfort

A minimalistic zipper reduces bulk, whilst a lightweight micro-grid stretch polyester is featured at the cuffs and armpits to enhance breathability and drying time. A soft, kissing-welt zipper garage at the chin provides next to skin comfort, whilst the two zippered hand warmer pockets that include internal mesh drop-in-pockets sit above the harness line in order to steer clear of pack straps.

  • Features a refined technical fit with offset seams for comfort under outerwear and packs.
  • 357 g (12.6 oz).
  • Made in Colombia.
