REI Co-op Sahara Convertible Pants Review

Overview

The REI Co-op Sahara Convertible Pants are a budget zip-off hiking pant in stretch nylon, built for hikers who want one garment to cover a cool morning and a hot afternoon. They are durable, pocket-rich and easy to convert without removing boots. They are also baggier, bulkier and slower to dry than the ultralight crowd’s usual pants.

Performance

Conversion. The Sahara’s best trick is the zip-off system. Vertical zippers run down each lower leg, so the legs come off without removing shoes or boots. That matters at a creek crossing or on a ridge where the temperature jumps. Color-coded zips at the thigh make it hard to put the wrong leg on the wrong side when converting back to pants, a small detail that anyone who has fumbled with identical zippers in a rainstorm will appreciate. Reviewers at CleverHiker called the conversion a breeze.

Comfort and breathability. A center gusset and a few percent of spandex give the fabric enough give for high steps and boulder scrambles. Owners praise the freedom of movement in the upper legs. Breathability is where opinions diverge from REI’s marketing. CleverHiker’s testers found the Saharas run warm in full-pants mode, since the baggy cut and fairly thick fabric trap heat. BetterTrail rated the fabric light-to-midweight and best suited to temperatures below about 60°F. The lower-leg vertical zips can be opened for airflow. Converting to shorts is the real cooling strategy.

Drying and weather. REI describes the nylon as quick-drying with a DWR finish, and it handles light drizzle and morning dew. CleverHiker’s testers, however, found the material slow to dry compared with thinner trail pants. BetterTrail scored weather resistance at 3 out of 5. The DWR is a splash-and-shower treatment, not rain protection, and it will fade with washing. Anyone who expects to wade rivers and dry out on the move should look at thinner fabrics.

Durability. This is the Sahara’s strong suit. CleverHiker’s testers knelt in mud and gravel, sat on rough rock and scraped between boulders, and the pants came through intact. Reinforced cuff backs protect the hems from boot abrasion, and reinforced front pockets add to the longevity. The one durability complaint is shape retention: BetterTrail noted the fabric stretches out of shape between washes.

Pockets. Six pockets is generous. The thigh cargos swallow a map, snacks or a buff. The security is less impressive. Only the right thigh pocket zips, and BetterTrail’s testers found it barely fits an iPhone 15. CleverHiker reported that loaded thigh pockets get baggier and swing while walking. Anyone carrying a phone or key on a steep trail will want to keep them in a closed pocket elsewhere.

Weight and bulk. At 386 g, the Saharas are not ultralight. A pair of light, non-convertible trail pants or running-style hiking shorts plus a windshirt weigh less. The zip-off hardware and vertical leg zippers add bulk, and BetterTrail flagged that in its review. The zippers also add small weight and chafe risk on long days, though flat seams keep the interior mostly smooth.

Sun protection. The UPF 50+ rating is a real benefit on exposed desert and alpine routes. Long legs mean no sunscreen on the shins, and the shorts-mode option helps if the trail turns hot.

Pros & Cons

Pros

• Zip-off legs come off over shoes via vertical zippers
• Color-coded thigh zippers prevent mixing up legs
• Tough nylon survives scrambling, kneeling and brush
• Six pockets, with reinforced front pockets and boot-proof cuff backs
• UPF 50+ fabric with a DWR finish
• Strong owner satisfaction: 4.2 out of 5 from more than 1,100 reviews on REI’s listing
• Price is modest, and REI regularly discounts it

Cons

• At 386 g, it is heavier than most dedicated ultralight pants or shorts
• Baggy fit and thicker fabric run warm in full-pants mode
• Reviewers found drying slower than the quick-dry label suggests
• Only one pocket zips, and it is a tight fit for large phones
• Zippers add bulk, and the fabric can stretch out between washes
• DWR is not meaningful rain protection

Who Should Buy This

The Saharas suit section hikers, weekend backpackers and travelers who want one durable pair of pants that can flip to shorts in the middle of a day and don’t mind a few extra ounces. They also suit anyone who wants lots of pockets and hard-wearing fabric at a price well under that of premium hiking pants. Thru-hikers counting every gram, hikers in hot, humid climates, and anyone who wants a close, fast-drying fit should look elsewhere, toward a lighter pair of woven nylon pants and separate shorts.

Verdict

The Sahara Convertible is a dependable, durable workhorse that does the zip-off trick better than most. It is not a lightweight or fast-drying pant, and the pockets are less secure than six pockets should be. Buy it at a discount for general hiking and travel; skip it for ultralight kits.
