The Western Mountaineering Lynx GWS carries a manufacturer-rated limit of -23°C and belongs to the brand's five-season expedition class, but it's cut short, for users up to 167 cm, unlike the regular-length cut used on the brand's other expedition bags. That shorter cut is the main reason it weighs just 1504 g with 851 g of 850+ fill power goose down — noticeably less than the longer Bison or Cypress at a comparable temperature range.
V-baffle construction, the same style used on the Bison, keeps the down from shifting under compression and holds an even insulation layer. The Gore Infinium (Gore Windstopper) shell adds a windproof, water-resistant membrane, while an insulated draft collar, draft tube, and full-length zipper cover the usual mummy-bag weak points.
Packed to 46 × 23 cm, it's a standard size for an expedition bag. The combination of a short cut and a high warmth rating makes it an interesting option for shorter users who need a genuinely warm bag without carrying unnecessary extra weight. Made in the USA.
